Chu Yang and Chu Ying arrived like a storm split in two.
They were five years older than Chu Yan, and at twelve they had already grown into the kind of presence that made corridors widen. Not because the palace feared them—though it did, instinctively—but because twins in the imperial line were rare enough to be treated as an omen.
Nobody had decided yet whether it was a good one.
They moved in tandem, always. Not identically, but in a rhythm so practiced it looked like choreography. Chu Yang first, louder, sharper, his true-form limbs thicker and more aggressive, coiling and uncoiling with restless energy as if stillness was a punishment. Chu Ying half a step behind, quieter, her limbs more fluid, her attention wider, catching everything her brother missed because he was too busy being the center of every room.
They had accepted their names with less ceremony than Chu Yun.
Chu Yang had laughed when Chu Yan first said it in court—a bright, sharp sound that startled two ministers—and then used it immediately, loudly, as if daring anyone to tell him not to.
Chu Ying had said nothing at all. She had simply looked at Chu Yan with an expression he couldn't read, and later that evening he heard her say "Chu Ying" to her own reflection in a polished corridor wall, so softly it was barely a vibration.
She had been practicing.
The thought made Chu Yan's chest ache in a way he couldn't explain.
Now, weeks after the naming had settled into the empire's bones like a new season, the twins descended on Chu Yan's quarters with the energy of two creatures who had been told to be patient for far too long.
Chu Yang arrived first.
He didn't knock. Knocking was a human concept that hadn't reached the palace yet. He simply pushed through the membrane with a burst of scent—sharp, bright, demanding—and his limbs were already reaching for Chu Yan before the rest of his body had fully entered.
"Little brother," Chu Yang announced, as if the room needed to be informed.
Chu Yan, who had been studying a structural layout of the palace's lower-level housing on a bioluminescent display, didn't look up.
"I'm busy," he said.
"You're always busy," Chu Yang said, and then he grabbed him.
It wasn't gentle.
Chu Yang's limbs wrapped around Chu Yan's smaller body and lifted him clean off the floor, coiling him against his chest like a prize. The grip was firm, almost too tight, the kind of affection that came from a body that didn't know how to be soft and refused to learn.
Chu Yan's limbs flailed once—Loss of dignity, his mind supplied coldly—and then went still, because struggling only made Chu Yang hold tighter.
"Put me down," Chu Yan said flatly.
"No," Chu Yang said, with the cheerful certainty of someone who had never once been refused by the universe.
Chu Ying entered behind him, silent as water.
Her gaze swept the room: the display, the housing layouts, the scattered notes Chu Yan had been compiling. Her attention lingered on the details in the way Chu Yang's never did. She absorbed. He consumed. That was their difference.
"He was working," Chu Ying said.
"He's seven," Chu Yang replied, as if that settled everything.
"I was working," Chu Yan confirmed, voice muffled against Chu Yang's chest.
Chu Yang's limbs shifted, rearranging Chu Yan so he was perched higher, almost draped over a shoulder. It was undignified. It was warm. Chu Yan hated that his body relaxed into it.
"You can work later," Chu Yang said. "You need to move. You've been in this chamber since morning. The attendants are whispering that you're becoming strange."
"I am strange," Chu Yan said.
Chu Yang snorted. A limb tightened briefly around Chu Yan's middle, a squeeze that was half-reprimand, half-affection.
Chu Ying moved closer.
She didn't grab. She never grabbed. She simply positioned herself beside them, her limbs extending slowly until one wrapped around Chu Yan's smaller tentacle with a gentleness that made the contact feel like an apology for her brother's roughness.
Her touch was warm and unhurried.
Chu Yan's body betrayed him again: he leaned into it.
For a moment, the three of them were tangled together in a way that would have looked alarming to any species that didn't understand ZERG affection. Limbs over limbs, coiled and layered, warmth shared through contact.
To anyone else, it might have looked like restraint.
To them, it was home.
Chu Yang broke the silence first, because Chu Yang always broke silence.
"The housing plans," he said, gesturing vaguely with a free limb toward the display. "What are those?"
Chu Yan blinked. "You noticed?"
"I'm not stupid," Chu Yang said, sounding mildly insulted. Then, after a beat: "Chu Ying noticed. She told me to ask."
Chu Ying's grip on Chu Yan's tentacle tightened by a fraction. Neither confirmation nor denial. Just presence.
Chu Yan hesitated.
He had not shared this particular project with anyone outside his own thoughts. Not Chu Yun, who would understand but would immediately begin calculating political cost. Not the Emperor, who would listen but whose approval came with weight. Not the Empress, who would support it but whose support would turn it into a palace initiative rather than something organic.
The twins were different.
The twins were chaos.
And chaos, sometimes, was the safest place to test an idea.
"The lower quarters," Chu Yan said carefully, "are built for function."
Chu Yang stared at him. "Everything is built for function."
"That's the problem."
Chu Ying's gaze sharpened.
Chu Yan shifted in Chu Yang's grip until he could face the display properly, one limb pointing at the layout.
"Low-class ZERG are housed in clusters. No separation. No personal space. No rest areas that aren't also work areas. They eat where they sleep. They sleep where they labor. Their whole life is one room that never changes."
Chu Yang frowned. Not with understanding yet. With the discomfort of someone being shown a wall he'd walked past a thousand times without seeing.
"They're low-class," he said slowly.
"They're alive," Chu Yan replied.
The words landed harder than he intended.
Chu Yang's limbs loosened slightly, not releasing him, but shifting. Processing.
Chu Ying spoke for the first time since entering.
"You want to change the housing."
Not a question. An observation.
Chu Yan nodded. "Modular. Separated spaces. Rest areas that are only for rest. Walls that respond to the individual, not just to rank."
"The palace already does that," Chu Yang said. "For us."
"Exactly," Chu Yan said. "For us."
Silence.
Chu Yang looked at the layout again, and Chu Yan watched something shift behind his brother's eyes. Not compassion—not yet. Chu Yang's mind didn't work in compassion first. It worked in fairness, in the hot, instinctive sense of balance that made him angry when things tilted wrong.
"That's…" Chu Yang started, then stopped.
His limbs coiled tighter around Chu Yan, unconscious, protective, as if holding him closer could make the problem smaller.
"That's a lot of ZERG," he finished quietly.
"Yes," Chu Yan said.
Chu Ying's gaze moved between them. Then she unwound herself from Chu Yan and crossed to the display.
Her limbs moved with precision, pulling up layers of the layout, examining structural capacity, resource allocation, spatial distribution. She read it the way Chu Yang couldn't: not with emotion, but with architecture.
Chu Yan watched her and felt something loosen in his chest.
She understood.
Not the "why" yet.
But the "how." And "how" was where empires actually changed.
"You'll need material redistribution," she said, still scanning. "The lower corridors use bio-resin grade four. It doesn't respond to individual scent. You'd need at least grade six to make walls adaptive."
"Grade six is reserved for imperial quarters," Chu Yang said.
"Then un-reserve it," Chu Yan said simply.
Chu Yang stared at him.
Then he laughed.
Not the sharp court laugh. A real one, startled out of him, too loud for the chamber. His limbs shook with it, jostling Chu Yan, who grabbed onto a coil for balance and glared.
"You're insane," Chu Yang said, with a warmth that sounded like admiration.
"I'm practical," Chu Yan corrected.
Chu Ying turned from the display. Her expression hadn't changed, but something in her posture had softened. She crossed back to them and, without asking, rewrapped her limb around Chu Yan's.
He let her.
For a long moment, the three of them stayed like that: Chu Yang holding him like a possession, Chu Ying holding him like a secret, and Chu Yan held between them, thinking of corridors he wanted to rebuild and lives he wanted to make room for.
Then Chu Yang spoke again, quieter now.
"Does Chu Yun know?"
Chu Yan shook his head.
Chu Yang's eyes narrowed. "He'll want to control it."
"I know."
"He'll make it political."
"Everything is political."
Chu Yang made a frustrated sound, a vibration that rattled through his limbs and into Chu Yan's body. "I hate that you're right."
Chu Ying squeezed once. "He's always right. That's why it's annoying."
Chu Yan looked between them—his twin siblings, older, stronger, louder than him in every physical way—and felt the strange, painful tenderness of being small and protected and understood.
It was a feeling he had not had on Earth.
Not like this.
Not wrapped in limbs that could kill and chose instead to hold.
"Will you help?" he asked.
He asked them both, but he looked at Chu Ying.
Because Chu Yang would say yes out of loyalty.
Chu Ying would say yes only if she believed it could work.
Chu Ying held his gaze for a beat.
Then she nodded, once.
Chu Yang tightened his grip immediately, as if the decision had already been made and he was claiming credit.
"Obviously," he said. "You think I'd let you do this alone? You can't even reach the upper displays."
Chu Yan's limb smacked the back of Chu Yang's head.
Chu Yang yelped.
Chu Ying made a sound that might have been laughter, if laughter could be silent.
And in the chamber, tangled together like a knot of warmth and stubbornness, the three youngest members of the imperial family began to plan something that would quietly shake the foundations of every corridor in the empire.
Outside, in the hive's deeper levels, a low-class ZERG pressed its back against a wall that did not respond to its touch, and whispered a name it had chosen three days ago, testing whether the sound still felt like it belonged.
It did.
