The thing about mornings in Atlantis—and Percy was developing opinions about this with the speed of someone who'd spent a century in a place where morning was a theoretical concept at best—was that they arrived with all the subtlety of a symphony orchestra having opinions.
Light filtered through the water in shafts of blue-green brilliance that would've been beautiful if Percy's brain had been awake enough to appreciate beauty. Instead, his brain was doing that thing where it insisted that consciousness was optional and sleep was a fundamental right that shouldn't be violated by things like "sunlight" or "the passage of time" or "responsibilities."
His body disagreed with his brain's assessment.
His body had spent a century on high alert, sleeping in shifts, always ready for the next attack. His body didn't understand concepts like "safe" or "rest" or "you can actually sleep for more than twenty minutes without something trying to eat you."
So Percy had woken approximately seventeen times during the night, hand going to a sword that wasn't there, shadows gathering defensively, crystal pulsing with alarm—only to remember, each time, that he was in Atlantis. In guest quarters. Safe.
Relatively safe.
Safe-adjacent.
By the seventeenth time, his body had reluctantly accepted that maybe—*maybe*—nothing was actively trying to kill him, and he'd managed something approximating actual sleep.
Which meant he woke feeling simultaneously more rested and more exhausted than he had in decades.
"Emotional processing," he muttered to the ceiling, which was vaulted and decorated with enough artistic merit to make Renaissance painters weep with envy. "That's what this is. I'm finally safe enough to actually *feel* things, and my psyche is taking advantage by throwing a century's worth of trauma at me all at once. Very efficient. Terrible timing. I hate it."
The ceiling, being a ceiling, offered no commentary.
Percy dragged himself out of bed—which was absurdly comfortable, probably enchanted, definitely the nicest thing he'd slept on since before Tartarus—and immediately regretted vertical existence.
His muscles ached. Not from injury—his father's healing had taken care of that—but from something deeper. Bone-deep exhaustion that came from holding tension for so long that relaxing felt like structural damage.
"This is fine," he told his reflection in the mirror. "This is normal. This is what happens when you finally stop running. Your body goes 'oh good, safe time, let's collapse now' and you just have to deal with it like a functional adult."
His reflection looked deeply unconvinced.
"Okay, fine, I'm not a functional adult. I'm a disaster held together with determination and poor decision-making. But I'm an *upright* disaster, which is progress."
A knock at the door interrupted his motivational self-talk.
"Percy?" Mera's voice, cheerful in that way that suggested she'd already been awake for hours and had possibly conquered several small countries before breakfast. "Are you decent? Or at least clothed? I'm not picky about decent but clothed is kind of mandatory for public spaces."
Percy looked down. He was wearing the pants from yesterday's formal wear because they'd been nearby and putting on pants had seemed like a reasonable first step toward civilization.
"Clothed," he called back. "Decent is negotiable but I'm wearing pants."
"Good enough."
The door opened and Mera swept in, looking entirely too energetic for someone who'd also attended last night's dinner. She was dressed casually—or what passed for casual in Atlantis, which still looked more put-together than Percy's best efforts—with her red hair pulled back in a practical braid.
"You look terrible," she announced cheerfully.
"Thank you. I was going for 'disaster chic.' Glad it's working."
"I meant you look tired. Exhausted, actually. Did you sleep at all?"
"Define 'sleep.' I achieved unconsciousness intermittently between episodes of panic and existential dread. Does that count?"
Mera's expression softened. "Nightmares?"
"More like my brain finally having a safe space to process a century of trauma and deciding to do it all at once in the form of extremely vivid anxiety dreams." Percy ran a hand through his hair. "But yeah. Nightmares. The usual. Dead friends, impossible choices, that time I had to—" He stopped. "Doesn't matter. I'm fine."
"You're not fine. But you're *here*, which is progress." Mera moved to his wardrobe—an actual wardrobe, full of clothes that had materialized overnight through what Percy assumed was either magic or very efficient servants—and started pulling out items. "Get dressed. Properly dressed. We're going exploring."
"Exploring what?"
"The city. Poseidonis. The capital of Atlantis and possibly the most beautiful place you'll ever see that's also full of political intrigue and ancient architecture." She tossed him a shirt that looked comfortable and practical. "I'm giving you the tour. The real tour, not the diplomatic 'look at our impressive monuments' tour. The 'here's where actual Atlanteans actually live' tour."
"Why?"
"Because you need to see more of this world than just palace interiors and formal dinners. Because understanding a place means seeing it, not just reading about it. And because—" She grinned. "—I want to show off. I'm very proud of Atlantis. Even the parts that are deeply flawed and politically complicated."
"Those are usually the most interesting parts."
"Exactly. Now get dressed. We're leaving in ten minutes. Try not to look like you're about to collapse. Or at least look like you're collapsing with style."
"I can do that. Probably. Maybe."
"That's the spirit. Commit to nothing, hope for the best."
Mera left him to dress, and Percy did his best to make himself presentable. The clothes fit well—whoever had stocked his wardrobe had either excellent predictive skills or had taken very detailed measurements while he was unconscious, which was vaguely concerning but also convenient.
He braided his hair—longer than he remembered, falling past his shoulders now, black with that strange tendency to look slightly green in certain light. Another gift from Tartarus. Another change he hadn't noticed happening until it was done.
The crystal pendant he tucked under his shirt. Less conspicuous that way. Less likely to attract attention.
His camp necklace he left visible. Those five beads were part of him in a way the crystal never would be. Reminders of who he'd been, who he'd loved, who he'd lost.
"Ready," he called out.
Mera reappeared, assessed him with a critical eye, and nodded approval. "Much better. You look almost human now. Very impressive."
"I *am* human. Mostly. Half human, anyway."
"Details." She linked her arm through his with that casual intimacy that suggested they'd known each other far longer than they actually had. "Come on. The city awaits. Try to look amazed. Atlanteans love when visitors are amazed by our accomplishments."
"I'm already amazed and we haven't left the palace."
"Then you're going to be *devastated* by the actual city. In a good way. Hopefully."
They left the guest quarters, Percy's guard detail falling into step behind them at a discrete distance. He'd almost forgotten about them—Orm's security precaution, undoubtedly. Watching. Reporting. Making sure the dangerous demigod didn't suddenly decide to destroy things.
Percy couldn't even be annoyed about it. It was smart. He *was* dangerous. They *should* be watching him.
The palace corridors eventually opened onto a balcony, and Percy stopped walking.
Stopped breathing.
Stopped processing reality in any meaningful way.
"Oh," he said quietly. "Oh, *wow*."
"I know, right?" Mera sounded smug. "Never gets old."
Poseidonis spread before them like a dream that had decided to become architecture.
The city sprawled across the ocean floor in cascading tiers, each level connected by sweeping bridges and waterways that served as streets. Buildings rose in impossible spirals of coral and crystal, some reaching hundreds of feet toward the surface, others diving deep into trenches that glowed with their own bioluminescence.
Everything was in motion—not chaotic motion, but *purposeful* motion. Atlanteans swimming through the city in streams of traffic that followed patterns Percy couldn't quite grasp but that clearly made sense to everyone involved. Markets bustled with activity. Plazas hummed with conversation. Gardens bloomed with colors that shouldn't exist underwater but did anyway, because apparently Atlantean horticulture had decided that laws of biology were more like friendly suggestions.
And the *light*—
Sunlight filtered down from above, refracted through water into shifting patterns that painted everything in blues and greens and silvers. But that wasn't the only light. The buildings themselves glowed—softly, constantly, like they'd captured pieces of stars and convinced them to stay. Bioluminescent flora lined every street. Crystal spires caught and amplified light in ways that created rainbow fractals across building facades.
It was like someone had taken Venice, Barcelona, and Coruscant, mixed them in a blender with bioluminescent deep-sea life and Greek architectural ambition, and then let the result marinate in impossibility for a few thousand years.
"This is insane," Percy breathed. "This is actually insane. How does any of this work? How is this structurally sound? How do you navigate? How do you—" He gestured helplessly at everything. "—*how*?"
"Magic, engineering, and a lot of trial and error spanning several millennia." Mera pulled him forward. "Come on. Gaping is allowed but we should gape while moving. I want to show you everything before Orm decides I'm a bad influence and confines you to palace grounds."
They descended from the palace via a series of platforms that operated on principles Percy didn't understand and possibly defied several laws of physics. Atlanteans nodded politely as they passed—some with curiosity, others with wariness, a few with outright hostility that they didn't bother hiding.
Percy couldn't blame them. He was a stranger. An outsider. A son of Poseidon who'd appeared from nowhere and immediately gotten royal protection.
If he were them, he'd be suspicious too.
They emerged into what Mera called the Scholar's Quarter—a district dedicated to learning, research, and the kind of intellectual pursuits that required impressive buildings and intimidating libraries.
"The Conservatory is here," Mera explained, gesturing to a structure that looked like someone had asked an architect to design "intimidating academic excellence" and the architect had delivered. "Where I study. Where I've been studying for years. Where I will apparently be studying until I either master every aspect of hydrokinesis or die of old age, whichever comes first."
"You don't like it?"
"I love it. It's fascinating and challenging and I get to spend my days manipulating water in increasingly complex ways." She paused. "I just wish it were less—formal. Less bound by tradition. The Masters are brilliant but they're very 'this is how we've always done things' and I'm very 'but what if we tried something completely different?'"
"Let me guess—they don't appreciate your innovative spirit."
"They appreciate it just enough to not expel me, but not enough to actually *listen* to my ideas." Mera sighed. "It's frustrating. I have theories about hydrokinetic applications that could revolutionize how we interact with water, but suggesting changes to thousand-year-old techniques is apparently heresy."
"Sounds familiar. Tradition versus innovation. It's a classic conflict."
"Are you speaking from experience?"
"My camp—Camp Half-Blood, where I trained—had the same tensions. Ancient training methods versus modern warfare. Greek versus Roman traditions. Old guard versus new ideas." Percy smiled slightly. "The old guard usually won. But sometimes—*sometimes*—the new ideas proved they were worth considering."
"How'd you manage that?"
"By being so spectacularly successful with the new ideas that they couldn't ignore them. Also by nearly dying a lot. Near-death experiences are very persuasive in demonstrating effectiveness."
"I'll keep that in mind. 'To prove your theories, nearly die.' Very practical advice."
"I'm full of practical advice. Most of it involves violence or poor decision-making, but still. Advice."
They passed through the Scholar's Quarter, Mera pointing out various buildings—libraries that housed texts older than written language, laboratories where researchers studied everything from marine biology to dimensional theory, amphitheaters where debates raged about philosophy and magic and whether surface dwellers should be considered sentient.
"That last one gets heated," Mera noted. "Surface dweller sentience is a controversial topic. Some Atlanteans think surface dwellers are just clever animals. Others think they're equals. Most fall somewhere in between."
"What do you think?"
"I think anyone who can build nuclear weapons and space stations is sentient, even if they make terrible decisions about how to use them." She squeezed his arm. "Also, I've met surface dwellers. They're people. Flawed, often foolish people, but people. Not animals."
"That's refreshingly reasonable."
"Don't let it get around. I have a reputation as a radical to maintain."
They continued deeper into the city, through markets where vendors sold everything from fresh kelp to enchanted crystals to weapons that hummed with power. Through residential districts where families lived in homes carved from coral or built from stone or grown from living reef. Through industrial areas where craftsmen forged metal and shaped glass and created art that would've made surface museums weep with envy.
And everywhere—*everywhere*—Atlanteans stared at Percy.
Some curious. Some fearful. Some angry.
But all *aware*.
"Does it bother you?" Mera asked quietly. "The staring?"
"I'm used to it. Been the center of attention—wanted and unwanted—since I was twelve." Percy met the gaze of an elderly Atlantean who was glaring at him with impressive intensity. The elder held his gaze for a moment, then nodded slightly. Acknowledgment, if not acceptance. "Besides, I'd stare too if I were them. Divine stranger appears from nowhere, possibly dangerous, definitely disruptive. That's worth staring at."
"You're very understanding about people treating you like a threat."
"That's because I *am* a threat. Understanding that makes everything simpler."
They reached a plaza dominated by a massive fountain—or what Percy assumed was a fountain, though given that they were underwater, the entire concept of fountains became philosophically complicated. Water flowed upward in defiance of gravity and common sense, forming intricate patterns that shifted and changed like liquid sculpture.
"This is the Heart of Poseidonis," Mera said. "Geographic center of the city. Symbolic center of Atlantean culture. And—" She gestured at the fountain. "—it's tied to your father's domain. To Poseidon himself. Watch."
She raised her hand, and the water responded instantly—streams diverting, patterns changing, the entire fountain reconfiguring based on her gestures. It moved like it was alive, like it wanted to please her, like it was asking *what shall we be?*
"That's incredible," Percy breathed.
"That's hydrokinesis. That's what I do. What I've trained my entire life to do." Mera lowered her hand and the fountain resumed its original pattern. "Try it. See if the water responds to you."
"I don't know if I should—"
"Percy, you're Poseidon's son. This fountain is literally tied to his power. If anyone has the right to interact with it, it's you." She nudged him forward. "Go on. Just—ask it to do something. Will it. The water will listen."
Percy approached the fountain cautiously, feeling the weight of dozens of eyes on him. Atlanteans had stopped to watch, curious about what the strange surface demigod would do.
No pressure.
He reached out—not physically, but with that sense he'd always had, that connection to water that was as natural as breathing. The fountain pulsed in response, acknowledging him, recognizing his blood.
*Hello*, Percy thought at it. *Can you hear me?*
The water *surged*.
Not violently. Not destructively. But *enthusiastically*, like a dog seeing its owner after a long absence. The fountain exploded upward in a column that must've been fifty feet high, sparkling with light, spinning in patterns that looked almost like—
"Is the fountain *dancing*?" Mera's voice was delighted. "Percy, you've made the fountain *dance*!"
"I didn't mean to—"
But the water was having too much fun to care about intent. It spiraled and dove, created shapes and forms, painted pictures in liquid that showed scenes Percy hadn't meant to share—Camp Half-Blood's beach, the shores of Montauk, a small apartment with blue cookies, his mother's smile, Annabeth's face—
Percy slammed his control shut, and the fountain collapsed back into its normal pattern, looking almost disappointed.
Silence filled the plaza.
Then, slowly, applause began. Light at first, then building. Atlanteans clapping—some enthusiastically, others grudgingly, but all acknowledging what they'd just witnessed.
"Show-off," Mera teased, but her eyes were bright with something that looked like pride.
"I didn't mean to—the water just—it was excited—"
"The water recognized you. Really, truly recognized you as Poseidon's blood. That's rare, Percy. Even royal Atlanteans don't usually get that strong a response." She pulled him away from the fountain, which seemed to track his movement wistfully. "You're going to have to learn control. Real control. Otherwise you'll be accidentally creating waterspouts every time you have strong feelings."
"I have strong feelings constantly."
"Then you'll have waterspouts constantly. That'll make dinner parties interesting."
They continued through the city, but the mood had shifted. Word of the fountain incident spread with the speed of gossip, which was apparently universal across all civilizations and dimensions. Atlanteans whispered as Percy passed. Not all hostile now. Some interested. Some excited.
Some terrified.
Percy pretended not to notice, but the crystal under his shirt warmed in response to his anxiety.
"Ignore them," Mera said softly. "They'll get used to you. Eventually. Probably."
"That's not very reassuring."
"I'm not very good at reassuring. I'm better at sarcasm and inappropriate jokes."
"Those work too."
They were heading toward what Mera called the Learning Halls—additional academic buildings, museums, archives of historical knowledge—when a voice called out:
"Mera of Xebel! A moment of your time, if you please!"
They turned to find an elderly Atlantean approaching—white-bearded, sharp-eyed, wearing robes that suggested either great wisdom or great eccentricity. The same man Percy had seen briefly at dinner, though they hadn't been formally introduced.
"Vulko," Mera said, and her voice held genuine warmth. "I was wondering when you'd track us down."
"I am old, not dead. I can still track enthusiastic students when they're showing divine strangers around the city." Vulko's attention shifted to Percy, and those sharp eyes assessed him with the sort of thorough examination that made Percy feel like a particularly interesting specimen. "Percy Jackson. Son of Poseidon. Survivor of Tartarus. Maker of fountains dance. You're quite the topic of conversation today."
"I've noticed," Percy said. "Sorry about the fountain. I didn't mean to—"
"Apologize for nothing. That fountain has been static and boring for three hundred years. You gave it personality. That's a gift." Vulko circled Percy slowly, still assessing. "You carry yourself like a warrior. Like someone who's seen too much combat and expects more. But your eyes—your eyes carry grief. Loss. The weight of choices that weren't really choices at all."
Percy said nothing. Couldn't say anything. This old man had seen too much, understood too much.
"Vulko is Queen Atlanna's chief advisor," Mera explained quietly. "Also a historian, scholar, and general repository of inconvenient truths. He knows everything about everyone and will absolutely use that knowledge to make you uncomfortable."
"It's not about discomfort," Vulko corrected. "It's about *understanding*. And I'm trying to understand you, Percy Jackson. You're a puzzle. A divine mystery wrapped in trauma and poor life choices."
"That's—actually very accurate."
"I'm old. I've seen patterns. You fit several of them." Vulko stopped his circling and looked Percy directly in the eyes. "You're dangerous. But not malicious. Powerful. But not cruel. Damaged. But not broken. Am I close?"
"Uncomfortably close."
"Good. That means my assessment skills haven't deteriorated." Vulko smiled—genuine and kind despite the brutal honesty. "Walk with me, both of you. I want to show Percy something. Something I think he needs to see."
Mera glanced at Percy, who shrugged. "Lead the way."
They followed Vulko through winding streets, deeper into the academic quarter, until they reached a building that looked older than the others—more weathered, more worn, covered in glyphs that Percy couldn't read but that felt *important* somehow.
"The Archives of Antiquity," Vulko announced. "Where we keep the oldest records. The most ancient knowledge. Things written before writing was properly invented, preserved through methods even we don't fully understand anymore."
He led them inside, and Percy felt the weight of *age* press against him. This place was old. Truly old. Old enough that the stones remembered things that had been forgotten elsewhere.
They descended—down stairs carved from single pieces of stone, past shelves holding scrolls and tablets and crystals that probably contained recorded knowledge—until they reached a chamber deep in the building's heart.
Vulko gestured to the walls.
They were covered in murals. Faded but still visible. Depicting scenes of Atlantis's history—its founding, its golden age, its wars, its triumphs and tragedies.
But one section caught Percy's attention. Made him stop. Made him forget to breathe.
Because the mural showed a figure—tall, powerful, wielding a trident that blazed with divine light. The figure was painted in blues and greens, crowned with coral and kelp, surrounded by sea creatures that bowed in reverence.
And the figure's face—
"Poseidon," Percy whispered.
"Yes," Vulko confirmed. "This mural is over four thousand years old. Painted when the gods still walked this world regularly. When Poseidon still visited Atlantis, still blessed its people, still—" He paused. "—still *cared* about what happened here."
Percy moved closer, drawn to the image like iron to a lodestone. He'd never met his father. Not properly. Not face-to-face. He'd received blessings, been claimed, felt divine attention—but he'd never actually *met* Poseidon.
And here was his face, preserved in paint older than civilizations.
His father looked—different than Percy had imagined. Kinder. More human. Less like an untouchable god and more like someone who might actually care about his children.
"He's not like that anymore," Percy said quietly. "In my world. My dimension. The gods are more—distant. They follow the Ancient Laws. Non-interference. They love their children but from a distance."
"That must be hard," Vulko said gently. "Having a father who exists but cannot truly be a father."
"It is." Percy's hand moved to his chest, to where the crystal pulsed. "I've spent most of my life trying to earn his attention. His pride. Trying to be worthy of being his son. And I don't even know if he knows what happened to me. If he knows I was in Tartarus. If he—" His voice cracked. "If he even remembers me."
"He remembers," Mera said firmly. She'd moved to stand beside him, solid and warm and *there*. "The ocean remembers you, Percy. The water itself knows your name. That doesn't happen unless Poseidon himself has marked you as important."
"Maybe. Or maybe the ocean just recognizes power. Recognizes survival."
"The ocean recognizes *family*," Vulko corrected. "And you, Percy Jackson, are family. Whether your father is present or not. Whether he claims you actively or not. You carry his blood. His legacy. His connection to the sea itself. That makes you family to Atlantis, whether we like it or not."
Percy looked at him sharply. "Whether you like it or not?"
"Oh, I like it. I think it's fascinating. But others—others will see you as a threat. As proof that Poseidon still meddles in mortal affairs. As evidence that the old ways aren't as dead as we thought." Vulko's expression grew serious. "You've upset the established order just by existing, Percy. That will have consequences. Some good. Some very much not good."
"I'm used to consequences."
"I imagine you are." Vulko gestured around the chamber. "But look at this room. Look at these murals. They tell the story of Atlantis's relationship with the divine. With the ocean. With power itself. And that relationship has always been *complicated*. Full of blessings and curses in equal measure."
He pointed to another section of the mural—this one showing Atlantis sinking, the city collapsing into the ocean, people drowning or transforming or fleeing.
"We were punished once," Vulko said quietly. "For hubris. For thinking ourselves equal to the gods. For reaching too high, too fast, too arrogantly. Poseidon himself brought us low. Sank our city. Killed thousands. And then—" He gestured to the next panel, which showed the survivors adapting, changing, learning to breathe water. "—he gave us a second chance. Transformed us. Made us creatures of the ocean. Gave us the ability to survive in the very element that had killed us."
"A punishment and a blessing," Mera said.
"The most divine gifts usually are." Vulko looked at Percy. "You're both too, aren't you? Punishment and blessing. The power you carry could destroy this city. But it could also save it. You're a crisis and an opportunity, walking around in the same body."
"I'm just trying to survive," Percy said.
"Survival is never *just* survival. Not when you're someone with your power. Every choice you make, every action you take—it creates ripples. Consequences. Changes. Whether you intend them or not."
Percy stared at the mural of Poseidon—his father, distant and powerful and impossibly complicated.
"I don't want to destroy anything," he said quietly. "I've destroyed enough. I just want—" He stopped, trying to find words for feelings he barely understood himself. "I just want to rest. To heal. To figure out who I am when I'm not just surviving."
"Then rest," Vulko said simply. "Heal. Figure yourself out. Atlantis will give you that space. But Percy—" His voice took on an edge. "—be prepared. Because the universe has a terrible habit of interrupting rest with catastrophe. Especially for people like you."
"People like me?"
"Heroes. Whether you want the title or not. Whether you accept it or not. You're a hero, Percy Jackson. And heroes don't get to rest for long. There's always another crisis. Another fight. Another choice between bad options and worse ones."
Percy wanted to argue. Wanted to say he wasn't a hero anymore, that he'd left that behind in Tartarus along with his innocence and optimism and most of his sanity.
But he couldn't.
Because Vulko was right.
Heroes didn't get to rest.
They got to keep fighting until they couldn't fight anymore.
And Percy had a terrible feeling that he could fight for a very, very long time still.
---
They left the Archives in heavy silence, the weight of ancient history and prophetic warnings pressing against them like deep water.
Mera eventually broke the quiet: "Well, that was cheerful. Nothing like ancient murals and ominous prophecies to really lighten the mood."
"Vulko has a gift," Percy agreed. "The gift of making everything feel simultaneously more meaningful and more depressing."
"It's a talent. He's been cultivating it for decades. Possibly centuries. I'm not entirely sure how old he is." Mera pulled Percy toward a different district—brighter, more lively, full of younger Atlanteans. "Come on. We need to do something that doesn't involve contemplating your divine trauma or the weight of existence. We need fun."
"I don't know if I remember how to do fun."
"Then I'll teach you. I'm an excellent teacher of fun. Very qualified. Absolutely certified in fun-having."
"By whom?"
"Myself. I certified myself. Very official process. Lots of paperwork."
Despite everything, Percy smiled. "Where are we going?"
"The Conservatory. I want to show you where I study. Where I've been learning to be absolutely amazing at water manipulation." Her eyes gleamed. "Plus, if we're lucky, some of my classmates will be there and I can show off by introducing them to an actual son of Poseidon. I'll be insufferable about it for weeks."
"That's your motivation? Showing off?"
"That's *always* my motivation. Also I genuinely think you'll find it interesting. We do things with water that would blow your mind."
"My mind has been blown pretty consistently since arriving here."
"Then one more blow won't hurt."
The Conservatory rose before them—all spiraling towers and open amphitheaters, designed to allow maximum water flow for practice. Percy could see students working in various spaces—young Atlanteans manipulating water in ways that looked like art, science, and magic all at once.
One student was creating intricate ice sculptures. Another was making water defy gravity in increasingly complex patterns. A third was doing something that looked like water was having an existential crisis about what shape it wanted to be.
"Impressive," Percy said.
"Wait until you see the advanced students." Mera pulled him toward one of the larger amphitheaters. "They can do things with water that shouldn't be possible. Things that make the Masters nervous because they don't have theoretical frameworks for them yet."
They entered the amphitheater to find it already occupied—a class in session, students practicing in formation, a stern-looking instructor calling out corrections.
The instructor noticed them immediately. Noticed Percy specifically.
"Mera," she said, her voice carrying that particular tone of someone addressing a student who was both brilliant and constantly causing problems. "You're supposed to be in Advanced Theory right now, not giving tours to—" She stopped, really looking at Percy. "—to divine anomalies."
"Master Ceres," Mera said cheerfully. "This is Percy Jackson. Son of Poseidon. I'm showing him around. Educational purposes. Very official."
"Nothing you do is official."
"Then this is my first official thing. Historic moment. You should be honored to witness it."
Master Ceres looked like she was experiencing physical pain from Mera's logic. But her attention remained fixed on Percy, assessing him with the kind of sharp evaluation that came from years of teaching students with dangerous powers.
"Son of Poseidon," she said slowly. "The one who made the Heart of Poseidonis dance."
"That was an accident."
"Accidents that involve divine power causing ancient fountains to exceed their designed parameters are rarely *just* accidents." But her tone wasn't hostile. Just wary. Curious. "Can you do anything else? Besides unintentional water choreography?"
Percy hesitated. "I can—I'm not really—my control is—"
"Show her," Mera urged. "Come on. Make water do something impressive. Anything."
"I don't want to—"
"Percy Jackson." Master Ceres's voice took on a different quality—still stern, but with a hint of invitation. "I've been teaching hydrokinesis for forty years. I've seen students with natural talent. Students with inherited power. Students with both. And right now, I'm seeing someone who's *terrified* of their own abilities. That's dangerous. More dangerous than the abilities themselves."
Percy met her gaze. "I'm not scared of my abilities."
"Then what are you scared of?"
"Losing control. Hurting someone. Becoming something worse than what I already am."
The amphitheater went quiet. Students had stopped practicing, listening despite themselves.
"Tell me," Master Ceres said, moving closer, "what's the worst thing you've done with your power?"
Percy's jaw tightened. "I drowned an army. Pulled the ocean into a canyon and drowned five hundred monsters at once. Listened to them scream as the water filled their lungs. Watched them die knowing I was the one killing them."
More silence. Heavy and absolute.
"And it haunts you," Master Ceres said. Not a question.
"Yes."
"Good." She smiled—small and sad and understanding. "That means you're not a monster. Monsters don't regret their kills. They don't question their actions. They don't lie awake wondering if there was another way." She gestured to the water in the practice pool at the amphitheater's center. "Show me something, Percy Jackson. Not something violent. Not something destructive. Show me something that represents who you want to be, not who you were forced to become."
Percy looked at the water. At all the eyes watching him. At Mera's encouraging expression.
At the crystal around his neck, pulsing with captured rivers.
"Okay," he said quietly. "Okay."
He reached out—not to control, but to *ask*. The water responded instantly, eagerly, like it had been waiting for permission.
And Percy created something he hadn't let himself create in a century.
Something from before.
Something from home.
The water rose and shaped itself into a small beach. White sand formed from tiny water droplets compressed and crystallized. Waves lapped at the shore—miniature but perfect, capturing the rhythm of the ocean he remembered from Montauk. A lighthouse materialized, glowing with soft blue light. Strawberries grew on vines made of water—translucent, impossible, beautiful. A pine tree stood at the edge, created from flowing water that somehow looked solid.
Camp Half-Blood.
Home.
The place he'd lost.
The place he could never return to.
Percy held the image for a long moment, pouring memory and longing and grief into the water, letting it become something more than just liquid. Letting it become a statement: *This is who I was. This is what I lost. This is what I'm trying to find again.*
Then, gently, he let it go. The image collapsed back into water, rippling once, returning to its natural state.
The amphitheater was absolutely silent.
Then Master Ceres did something unexpected.
She bowed.
Not deeply. Not the formal bow reserved for royalty. But a bow of respect—teacher to student, one wielder of power to another.
"That," she said quietly, "was not hydrokinesis. That was *art*. That was memory made manifest. That was—" She straightened, and her eyes were suspiciously bright. "—that was someone showing us their heart."
Percy felt his throat go tight. "It was just—"
"It was *everything*," Mera breathed. She'd moved closer without him noticing, her hand finding his arm. "Percy, that was—I've never seen anything like that. The detail. The *emotion*. You didn't just shape water. You made it *remember* with you."
"I didn't mean to—"
"Stop apologizing for being extraordinary," Master Ceres interrupted. "You have a gift. A genuine, rare gift. And yes, it's been twisted by trauma and violence and whatever hell you've survived. But it's still *there*. Still beautiful. Still worth developing." She paused. "I would like to work with you. If you're willing. Not to make you a weapon. But to help you remember how to make your power serve *you*, not just your survival."
Percy stared at her, processing. "You want to teach me?"
"I want to help you teach yourself. There's a difference." Master Ceres gestured at her students, who were still watching with expressions ranging from awe to envy to fear. "These students learn techniques. Methods. How to manipulate water efficiently, effectively, safely. You don't need that. You need to learn how to trust yourself. How to create without fearing destruction. How to let your power be something other than a weapon."
"I don't know if I can."
"Neither do I. But I'd like to try." She smiled. "Besides, Mera will never forgive me if I don't at least offer. She's very attached to you already. It's quite adorable."
"I'm not *attached*," Mera protested, her face flushing slightly. "I'm *invested*. In his development. As a person. And a hydrokinetic. Purely professional interest."
"Of course," Master Ceres said, in the tone of someone who absolutely did not believe that. "Purely professional."
One of the students—younger, maybe fifteen, with the kind of bright curiosity that suggested either great potential or great capacity for causing problems—raised their hand tentatively.
"Master Ceres? Can we ask him questions? The son of Poseidon? Or is that—would that be inappropriate?"
Master Ceres looked at Percy. "Your choice. You're under no obligation to satisfy their curiosity."
Percy looked at the students. Young faces, eager and scared and fascinated all at once. He remembered being that age. Being desperate to understand power, understand legacy, understand what it meant to be different.
"Sure," he said. "Questions are fine. As long as they're not—" He paused. "—as long as you understand I might not answer everything."
The student who'd raised their hand practically vibrated with excitement. "Is it true you've been to Tartarus? The real Tartarus? The prison of the Titans?"
"Yes."
"And you survived for—people are saying a century. Is that true?"
"Yes."
"How?" The question burst out, desperate and awed. "How did you survive that long in the worst place in existence?"
Percy was quiet for a moment, choosing words carefully. "I survived by becoming something I didn't want to become. By learning to fight better than the things trying to kill me. By giving up pieces of myself to stay alive. By—" He stopped. Started again. "By deciding that dying wasn't an option, even when dying would've been easier. Even when dying would've been kinder."
"Do you regret it?" Another student, older, with eyes that had seen enough to ask hard questions. "Surviving, I mean. Do you wish you'd just—given up?"
"Sometimes." The honesty felt like pulling out a splinter. "Sometimes I wonder if fighting that hard, for that long, cost more than it saved. If the person who came out of Tartarus is even the same person who fell in."
"But you're still here," Mera said softly. "That has to count for something."
"Maybe. I'm still figuring that out."
More questions came—about power, about technique, about what it felt like to command water on instinct rather than training. Percy answered what he could, deflected what he couldn't, and tried not to let the weight of their attention crush him.
These were kids. Young Atlanteans trying to understand their own powers. And he was—what? A cautionary tale? An inspiration? A warning about what happened when power and trauma collided?
Probably all three.
Eventually, Master Ceres called a halt to the questioning, sensing Percy's exhaustion. "Enough. Back to practice. And I want to see *precision* today, not power. Control matters more than strength."
The students dispersed reluctantly, casting final glances at Percy that ranged from admiration to uncertainty.
"Thank you," Master Ceres said to Percy. "For indulging them. And for being honest. They need to understand that power comes with costs. That being extraordinary doesn't mean being invulnerable." She paused. "The offer stands. If you want training—real training, not just technique but *philosophy*—find me. I'm here most days."
"I'll think about it," Percy said.
"That's all I ask." She turned to Mera. "And you—Advanced Theory. Now. You've missed half the session already."
"But—"
"*Now*, Mera of Xebel. Before I decide your tour guide services constitute truancy and report you to the Academic Council."
"You wouldn't."
"I absolutely would. I'm old. I can do whatever I want."
Mera sighed dramatically but squeezed Percy's arm. "I'll find you later. Try not to cause any international incidents while I'm gone."
"No promises."
She left, casting one final smile over her shoulder, and Percy found himself alone with Master Ceres.
"She likes you," the older woman observed. "Quite a lot, actually. More than she's liked anyone in years."
"We just met."
"Some connections are instant. Lightning rather than slow building." Master Ceres began organizing the practice area, a casual gesture that suggested this conversation was important enough to have while doing mundane tasks. "Be careful with her heart, Percy Jackson. She pretends to be all confidence and sarcasm, but underneath—underneath she's desperately lonely. Desperately wanting someone who understands what it's like to be powerful and isolated."
"I'm not—I'm not good for her. I'm not good for anyone right now."
"Probably not. But that's not your choice to make. She's decided you're worth knowing. Worth caring about. You can accept that or reject it, but you can't decide what she's allowed to feel."
Percy didn't have a response to that.
"Besides," Master Ceres continued, "sometimes the best thing for healing is connection. Is letting someone care about you even when you're convinced you don't deserve it. Even when you're terrified of hurting them."
"You sound like you're speaking from experience."
"I'm old and I've loved unwisely more times than is reasonable. Experience is all I have left." She smiled. "Go. Explore more of the city if you like. Or return to the palace. Or find a quiet corner and process everything. Whatever you need. But Percy—" She met his eyes directly. "—don't let your past convince you that you don't deserve a future. You survived for a reason. Figure out what that reason is."
She left him then, returning to her students, and Percy stood alone in the amphitheater, surrounded by water that whispered his father's name.
---
He ended up walking. Not with any destination in mind, just—moving. Processing. Thinking.
The city flowed around him. Atlanteans going about their lives, conducting business, meeting friends, arguing about politics, living in the casual way people lived when they weren't constantly expecting death.
It felt surreal.
Percy had spent so long in survival mode that watching people exist *peacefully* felt like observing an alien culture. They weren't looking over their shoulders. Weren't cataloguing exits. Weren't calculating the most efficient way to kill everyone in the immediate vicinity.
They were just—living.
When had he forgotten how to do that?
His wandering eventually brought him to a residential area—quieter than the markets, more intimate than the grand plazas. Families here. Children playing in gardens, their laughter carrying through the water. Elderly Atlanteans sitting in front of homes, watching the world pass.
Normal.
So achingly normal.
"You're the son of Poseidon."
Percy turned to find an elderly Atlantean woman watching him from her doorway. Her face was weathered, her hair white as foam, but her eyes were sharp and kind.
"Yes," he said.
"You look lost."
"I am. Geographically and existentially."
She laughed—a sound like waves on sand. "Come. Sit. I'll give you tea and you can be lost in company rather than alone. It's better that way."
Percy hesitated. "I don't want to intrude—"
"It's not intrusion if I'm inviting you. Come." She gestured to a small courtyard attached to her home. "I'm Tethys. And before you ask—no, not the Titan. My parents had a sense of humor. A terrible sense of humor, but humor nonetheless."
Despite himself, Percy smiled and followed her.
The courtyard was small but beautiful—filled with bioluminescent plants that cast soft light, a small fountain (of course there was a fountain), comfortable places to sit that looked organic rather than constructed.
Tethys produced tea from somewhere—Percy had no idea how tea worked underwater but apparently it did—and poured two cups with the practiced ease of someone who'd done this thousands of times.
"So," she said, settling into her seat. "The lost son of Poseidon. That's quite the title. Are you living up to it? The 'lost' part, I mean. The 'son of Poseidon' part seems fairly self-evident."
"I'm very lost," Percy admitted. "I don't know where I am, who I am, what I'm supposed to do, or whether I'm making anything better or worse by being here."
"That's very honest. I appreciate honest." Tethys sipped her tea. "Do you want advice from an old woman who's seen three centuries of people being lost?"
"Please."
"Being lost is temporary. Being unwilling to ask for directions is permanent." She smiled at his expression. "I know, I know. Terrible advice. Very obvious. But you'd be surprised how many people wander forever because they're too proud to ask where they're going."
"I don't know what to ask for. I don't know what I need."
"Then start smaller. What do you want? Right now. In this moment. Not in the grand cosmic sense, but in the immediate, practical sense."
Percy thought about it. Really thought.
"I want to stop being scared," he said finally. "Scared of myself. Of what I can do. Of what I might become. I want to—" His voice cracked. "—I want to feel safe. Actually safe. Not just temporarily not-in-danger, but *safe*. Like I can put down the sword and the armor and just—exist. Without constantly waiting for the next fight."
"That's a good want. Achievable, even. Difficult, but achievable." Tethys leaned forward. "Can I tell you something? Something I learned after my husband died in the last surface war?"
"Of course."
"Safety isn't a place. It's not something external you can find or build or protect. It's something internal you have to *create*. It's the decision to trust—not blindly, not foolishly, but consciously. To say 'yes, the world is dangerous, yes, things could go wrong, but I'm going to live anyway. I'm going to connect anyway. I'm going to care anyway.'"
"That sounds terrifying."
"It is. Absolutely terrifying. But Percy—" Her eyes held his. "—you've already survived the worst thing you could imagine. You've been to Tartarus and come back. What's left to be scared of?"
"Everything. I'm scared of everything."
"Good. Fear means you're alive. Fear means you still have something to lose. Fear means you haven't given up on the possibility of happiness." She smiled. "Use that fear. Let it motivate you to build the life you want, not hide from the life you're afraid of."
Percy stared into his tea—which was glowing slightly, because apparently even beverages in Atlantis had flair—and felt something shift in his chest.
"How do I do that?" he asked quietly. "Build a life when I don't know if I deserve one?"
"You do what everyone does. You take one day at a time. You accept help when it's offered. You let people care about you even when your brain insists they shouldn't. You make mistakes and you learn from them and you keep going." Tethys reached across and patted his hand. "And you remember—you're not the first person to come back from hell changed. You won't be the last. But you *came back*. That's what matters. You didn't stay there. Didn't let it keep you. That takes strength most people don't have."
"It doesn't feel like strength."
"Strength never does. Not to the person being strong. It just feels like stubbornness and spite and refusing to quit." She grinned. "Which, coincidentally, are also excellent qualities for survival."
They sat in comfortable silence after that, drinking glowing tea, watching the water flow through the courtyard, existing in the peaceful company of two people who understood loss.
Eventually, Percy stood to leave.
"Thank you," he said. "For the tea. And the wisdom. And not running away screaming when I showed up."
"I'm too old to run anywhere. Walking is my maximum speed." Tethys walked him to the courtyard entrance. "Come back anytime, Percy Jackson. My door is open. Quite literally—I don't lock it. Very trusting. Possibly foolish. But I've lived this long without dying horribly, so my system works."
Percy left feeling lighter than he had in—he didn't know how long. Decades, maybe. A century.
Lighter, but still lost.
Still not sure what came next.
But maybe—*maybe*—that was okay.
Maybe being lost was just the first step to being found.
