The outskirts of Patrain were never merely a forest. To the uninitiated, the towering conifers and thick ferns were a scenic backdrop to the bustling trade city.
To the kingdom, it was a "Breeding Ground"—a volatile ecosystem of lethal intent. Beneath the emerald canopy, the food chain was written in blood: killer rabbits that could decapitate a man in a single leap, acidic slimes that dissolved armor into hissing vapor, and the ever-present, cackling green tide of Goblins.
The Blue Fang party moved through the undergrowth with the practiced ease of those who had survived the "low-level" grind. They were a study in textbook party composition.
Kabal, the Magic Swordsman, led the vanguard with a blade that flickered with faint elemental sparks.
Elen, a mage whose pride was as sharp as her incantations, hovered in the center.
Gido, a wiry man with the shifting eyes of a career thief, trailed behind, a notched arrow always resting against his bowstring.
They were consistent. They were reputable. And today, they had a fourth.
"Keep your guard up, Nana," Kabal said, his voice a smooth, reassuring baritone. "The wolf tracks are fresh. Stay behind my shoulder and watch for flanking maneuvers."
Nana, a young swordswoman with a polished blade and eyes full of idealistic fire, nodded fervently. She had heard the rumors—that this trio had once brought down a Hill Troll. Joining them felt like a golden ticket to the upper tiers of the Adventurer's society.
"I won't let you down, Leader," she whispered, her knuckles white on her hilt.
"We know you won't," Elen added with a thin, unreadable smile. "You're exactly what we need for this trip."
They pushed deeper into the "Yellow Zone," an area where the monsters grew larger and the shadows longer. The air grew heavy, smelling of wet earth and something metallic. Suddenly, the birds went silent.
Snap.
A single twig broke. Then came the sound of a thousand dry leaves skittering. From the dense thicket, eyes—beady, yellow, and overflowing with malice—began to peer out.
One goblin. Ten. Fifty. Then, a sea of green flesh and rusted iron emerged.
"A legion..." Gido hissed, his bravado vanishing as he fumbled a second arrow. "Kabal, there's too many! This isn't a scouting party, it's a war band!"
"Retreat!" Kabal roared. "Back to the clearing! Form a defensive triangle!"
They ran, but the forest seemed to conspire against them. The goblins moved with a terrifying, hive-minded coordination, flanking them through the brush.
Nana's heart hammered against her ribs like a trapped bird. She parried a rusted dagger, her blade singing as she cut down a screeching scout, but for every one she killed, three more took its place.
They reached a narrow pass between two massive ancient oaks. Kabal, Elen, and Gido surged through. Nana was a mere three steps behind.
"Help me clear the path!" Nana shouted, lunging at a goblin that tried to grab her ankle.
The three veteran NPCs stopped. They didn't turn to fight. They turned to look at her. There was no fear in Kabal's eyes—only a cold, calculated indifference. He signaled Elen with a sharp nod.
"Elen, now!"
The mage didn't hesitate. Her staff glowed with a muddy, brown light. "O Earth, heed my call—Rise and Divide!"
The ground groaned. A massive slab of stone and compacted dirt surged upward, erupting from the forest floor. It slammed into place with a deafening thud, sealing the pass.
Nana slammed her hands against the rough stone. "Elen! What are you doing? Open the wall! I'm still out here!"
On the other side, she heard a chuckle. It wasn't the sound of a hero; it was the sound of a merchant who had just closed a profitable deal.
"It's a tragic situation, Nana," Kabal's voice drifted over the top of the wall, growing faint as he began to run.
"Truly. But look at them—they're hungry. If we don't use you as a diversion, all of us are going to die. So, be a good sacrifice, little girl. Give us enough time to reach the gates, and we'll make sure your name is carved on the memorial stone."
"Kabal! Gido! Please!"
"Don't take it personally," Gido's voice added, retreating rapidly. "It's just high-risk, high-pay. You're the cost of our lives today."
Silence followed, save for the rhythmic thwack of goblin clubs hitting shields and the guttural laughter of the surrounding horde.
Nana turned her back to the wall. Her hope didn't vanish—it transmuted into a cold, desperate rage.
She fought. She swung her sword until her muscles burned like acid. She retreated into a thicket, her cloak shredded, her blood slicking the hilt of her weapon.
She managed to fell four, then five, but as she reached a small clearing, she saw them. Eight goblins, larger than the others, blocking her only path of escape.
She slumped against a tree, her breathing ragged. Her vision blurred. So this is the end, she thought. Betrayed by the 'reassuring' veterans. Consumed by the filth of the forest.
She closed her eyes, waiting for the first blade to sink in. Instead, the air screamed.
"Magic Missile."
"Fireball."
"Magic Missile."
The incantations were uttered with a rhythmic, machine-gun precision. Nana's eyes snapped open.
Three bolts of lethal cyan energy streaked through the air, moving so fast they left trails of ionized air. They didn't just hit the leading goblins; they punched through their skulls with the force of ballista bolts, spraying dark ichor across the leaves.
Before the remaining monsters could even shriek, a sphere of roiling orange flame condensed in the center of their rank.
BOOM.
The explosion was controlled, a pressurized wave of arcane fury that didn't just burn—it disintegrated. The goblins were silenced instantly, turned into charred husks that crumbled into ash before they hit the dirt.
Nana stared, frozen. Standing at the edge of the clearing was a man who looked like he had walked out of a different world. His hair was the color of fresh snow, and his eyes—a piercing, crystalline sapphire—seemed to glow with an inner light.
As her knees finally gave out, he was there. He moved with a grace that defied the laws of the muddy forest floor, catching her before she collapsed into the muck.
"It's over," he said. His voice was low, grounding, and devoid of the false bravado Kabal had worn. "You're safe."
Nana clung to his cold armor, her body racking with heaving, hysterical sobs. The terror of the betrayal, the looming threat of the "breeding pits" the goblins kept for human women—it all came pouring out.
"They... they left me," she choked out. "The Blue Fang... they built a wall..."
"I know," the man said, his gaze shifting to the earth wall in the distance. "I sensed the mana spike in this direction. I know, cowards usually leave a trail."
He helped her sit against a mossy log. "I am Arthur. A solo adventurer. Take a breath. The immediate threat is dead."
But Arthur didn't look relaxed. He stood up, his brow furrowed. He closed his eyes, and Nana felt a ripple in the air—a heavy, vibrating pressure that made her skin crawl.
"Magic Detection: Maximum Output," he whispered.
In Arthur's mind, the world faded into a grid of energy. He pushed past the birds, the wolves, and the ambient silence of the trees. Two miles out, he hit a barrier of pure, concentrated malice. It wasn't a group. It wasn't a legion.
It was an army.
"Ten thousand," Arthur muttered, his sapphire eyes snapping open. They were no longer calm; they were shards of ice. "They have a Lord. A Goblin Lord has unified the tribes."
Nana's face went pale. "Ten... thousand? Patrain... the guards aren't ready. They're not expecting a goblin siege!"
Arthur looked at the horizon. The sun was dipping below the tree line, casting long, bloody shadows across the forest.
The city of Patrain flickered in the distance, its torches lit for a peaceful evening. If that green tide hit those walls tonight, the city would be a graveyard by dawn.
He turned to Nana, gripping her shoulders. His intensity was terrifying, yet it was the most reassuring thing she had ever felt.
"Nana, listen to me. I cannot carry you and fight a ten-thousand-strong vanguard. You are the only one who can warn them."
"But you're just one person!" she cried. "You'll die! Come with me, we can run together!"
Arthur looked toward the dark woods, where the first rank of the goblin army was beginning to emerge like a green tide, their drums beginning a low, rhythmic thumping that shook the earth.
"If I run, they reach the gates before the oil is hot and the archers are manned," Arthur said.
"Nana, when you get to the gate, you don't stop. You run to the Earl's manor. You tell the guards that the forest is moving. Tell them a Goblin Lord is at their doorstep. If anybody stops you—the guards, the knights—you tell them it is a message from Arthur."
"But Arthur..." she whispered.
"Go!" he commanded. "Run like the wind is at your back. I will make sure they don't take a single step toward those walls until you've reached the Earl."
Nana stood, her legs shaking, but she saw the difference then. Kabal, the man she trusted, had used her as a shield to save his own miserable skin. Arthur, a stranger who owed her nothing, was standing as a shield for a city of thousands.
"I'll tell them," she promised, her voice strengthening. "I'll tell everyone." She turned and sprinted toward the city, the adrenaline of his command fueling her tired limbs.
Arthur watched her go until she was a speck in the twilight. Then, he turned back to the forest. He drew a sword that seemed to hum with the same sapphire light as his eyes.
He felt his mana pool—it was low, drained from the multi-casting and the detection, but his resolve was a bottomless well.
The first rank of Goblins broke into the clearing. Hundreds of them, led by a hulking Hobgoblin in scrap-iron plate. They stopped when they saw the lone man standing in their path.
Arthur raised his blade, the tip pointed directly at the heart of the horde.
"You want the city?" Arthur's voice carried through the trees, cold and absolute. "You'll have to pay for every inch in blood. And I've come to collect."
As the green tide roared and surged forward, the lone adventurer stepped into the shadows to meet them.
