The third day broke like a wound.
Sejin woke to the sound of breaking ice. Not cracks—shatters. The frozen river had exploded in the night. Deep Uras poured from the fissures like maggots from a corpse, their pale bodies twisting, their faceless heads scanning for warmth.
Sora was already at the ridge, her Ventus blade flashing. Jae stood beside her, his bad leg braced against a stone, his sword cutting down one Ura after another. Yuna was behind them, her Aqua light flowing between the fighters, healing cuts, sealing gashes, keeping them upright.
Sejin ran.
His claw scraped the stone. His shadow blade formed in his right hand. He leaped over a fallen tent, slid across the ice, and drove his blade into a Deep Ura's chest.
The creature shrieked. Black blood sprayed. Sejin twisted, pulled, moved to the next.
"There are too many," The Other said.
"I can see that."
"The camp is going to fall."
"Then I'll hold it up."
---
Lady Seri's ships did nothing.
They sat on the ice, silver and white, their Lux crystals glowing, their decks crowded with watching Vessels. They were waiting. Waiting for Sejin to break. Waiting for the camp to die.
Mira stood at the bow of the lead ship, her platinum hair whipping in the wind, her hands clenched at her sides. She was not fighting. She was not helping.
She was watching.
Sejin caught her eye for a moment. She looked away.
"She's not coming," The Other said.
"She can't."
"Then we die alone."
"Not alone."
Sejin turned. Sora was beside him, her blade dripping black blood. Jae was on his other side, limping but standing. Yuna was behind them, her bandaged hands glowing.
"Together," Sora said.
"Together," Jae echoed.
Yuna nodded.
Sejin raised his claw.
"Together."
---
The Deep Uras came in waves.
The first wave was scattered—individual creatures, testing the defenses. Sora cut them down. Jae stabbed them through. Yuna healed the wounds they left behind.
The second wave was organized. They moved in pairs, flanking, distracting, attacking from blind spots. Sejin's claw caught one by the throat and unraveled it. Another grabbed his leg. He kicked it off, stabbed it, moved on.
The third wave was a tide.
They poured from the fissures—dozens, hundreds, their pale bodies filling the ice field, their faceless heads turned toward the camp. The soldiers screamed. The tents collapsed. The stone spires cracked under the weight of them.
Jae went down.
A Deep Ura had caught his bad leg, pulled him off balance. He fell hard, his sword skittering across the ice. Another Ura lunged for his throat.
Yuna intercepted it.
Her bandaged hands grabbed the creature's face. Her Aqua light flared—not healing, but burning. The Ura shrieked, dissolved, fell apart. Yuna staggered back, her hands smoking, her face pale.
"Yuna!" Jae crawled to her.
"I'm fine," she gasped. "I'm fine."
She wasn't fine. Her bandages were soaked with black blood. Her hands were shaking.
Sejin saw all of this in a breath.
And he made a choice.
---
"The Other," he said.
"Finally."
"I need power. Not you. Power."
"You can't have one without the other."
Sejin's claw pulsed. The purple light flared, bright enough to cast shadows across the ice.
"Then make a deal with me."
"A deal?"
"You give me power. Enough to save them. Enough to hold this ground. And when you want control... I won't fight you."
The Other was silent for a long moment.
Then:
"You would give yourself to me? Voluntarily?"
"To save them. Yes."
"You're a fool."
"I know."
"But you're my fool."
The purple light exploded.
---
Sejin's body screamed.
Power flooded his Vein—not Source, but Void, raw and ancient and hungry. His claw expanded, crystal growing up his arm, over his shoulder, across his chest. His eyes became voids—purple and black, endless.
But he was still himself.
Barely.
The Other's voice was in his ears, his skull, his blood.
"Fight, little corpse. I'll hold the door."
Sejin moved.
He crossed the ice field in a heartbeat. His claw caught a Deep Ura by the head and pulled. The creature unraveled, its Source flowing into him, feeding the Void.
Another Ura lunged. He sidestepped, drove his shadow blade through its chest, and absorbed it.
Another. Another. Another.
He became a storm. A whirlwind of purple light and black crystal, cutting, unraveling, consuming. The Deep Uras fell before him like wheat before a scythe.
Sora stared.
"What is he?" Jae whispered.
"He's Sejin," Yuna said. "Fighting."
---
The tide turned.
The Deep Uras, for the first time, hesitated. They had no faces, no eyes, but they felt fear. The thing in the camp's center was not prey. It was predator.
They retreated.
Not all at once—some kept fighting, kept lunging, kept dying. But the tide receded. The fissures stopped producing. The ice field fell silent.
Sejin stood at the center of the carnage, his claw dripping black blood, his eyes still voids, his breath ragged.
"They're running," The Other said.
"They're regrouping."
"Same thing, different word."
Sejin's claw pulsed. The purple light dimmed.
He looked at the ships.
Lady Seri stood at the bow of the lead vessel, her silver robes immaculate, her cold blue eyes fixed on him. She had seen everything. The power. The control. The deal.
She was afraid.
Sejin smiled. It was not a kind smile.
"Three days," he called across the ice. "I'll come to you on three days. Not before."
Lady Seri said nothing. She turned and walked back into her ship.
The Lux crystals pulsed.
The fleet waited.
---
Sora reached him first.
Her hand grabbed his arm—the human one, not the claw. Her brown eyes searched his face.
"Are you still you?"
"I think so."
"You think so?"
"The Other made a deal. Power for control. Someday."
Sora's grip tightened. "Someday?"
"Someday."
She didn't let go.
---
Jae limped over, Yuna beside him. Yuna's hands were still smoking, but she was standing. Jae's leg was bleeding again, but he was standing.
"We held," Jae said.
"We survived," Yuna corrected.
"Same thing, different words."
Sejin looked at them. Three people who had chosen to stand beside him. Who had fought for him. Who had almost died for him.
"Thank you," he said.
"Don't thank us," Sora said. "Thank yourself. You made the deal. You saved us."
Sejin looked at his claw. The purple light was steady.
"I made a deal with a monster."
"Then we'll help you break it. When the time comes."
---
They walked back to the camp together.
The tents were destroyed. The supplies were scattered. The stone spires were cracked and bleeding black ice. But the people were alive. The soldiers were alive. The fighters were alive.
Sejin sat on a boulder at the edge of the camp, his claw resting in his lap, his grey eyes fixed on the ships.
"You saved them," The Other said.
"I saved them."
"Now you owe me."
Sejin's jaw tightened.
"I know."
"When I call, you'll answer."
"I know."
"No hesitation. No resistance. You let me in."
Sejin closed his eyes.
"I know."
He opened them.
The ships waited.
The ice waited.
The King waited.
But Sejin Yun, for the first time in seven years, was not alone.
