The first thing Chai learned about himself was that he never got warm.
Not in summer, when other children peeled off their shirts and ran through sprinklers. Not under blankets his foster mother piled on him like offerings to a god she didn't believe in. Not even when he pressed his palms against the kitchen stove, curious, desperate, hoping—until the skin blistered and still the cold remained, deep in his bones, deeper than any fire could reach.
He was seven when he stopped hoping.
He was twelve when he stopped wondering why.
And he was seventeen when the first monster found him.

The night it happened, Chai was working the late shift at Achille's Diner, a twenty-four-hour grease trap on the edge of town where the customers were either truckers, insomniacs, or people running from something. Chai fit the last category, though even he couldn't have said what he was running from.
Everything, probably. Nothing. The cold that lived in his chest like a second heart.
"Order up," called Yannis, the cook, sliding a plate of pancakes across the counter. "Table six. Kid's gotta be, what, five? Eating enough for five."
Chai grabbed the plate. "Growing."
"Growing into a small horse, maybe."
The diner was quiet for a Tuesday night. A trucker nursed coffee in the corner booth. An old woman read a paperback near the window. And at table six, a little boy sat alone, kicking his legs, watching the door like he expected someone to walk through it.
Chai set the pancakes down. "Where's your mom, kid?"
The boy looked up. His eyes were wrong—too old, too knowing, the color of river stones after rain.
"She's not coming," he said.
Chai frowned. "You waiting for someone else?"
The boy tilted his head. "You don't feel warm. Everyone else feels warm. Like little fires. But you're..." He reached out, fast as a snake, and grabbed Chai's wrist.
His hand was burning hot.
Chai jerked back. The cold in his chest surged—a reflex he didn't understand, didn't control. The boy's eyes widened. For one split second, his skin sizzled where he'd touched Chai, like water on a hot skillet.
Then the boy smiled.
"Found you," he whispered.
And his face melted.
Chai stumbled backward, heart hammering. The boy's features ran like wax, sliding, reforming—skin bubbling, bones cracking, body expanding. In three heartbeats, the child was gone. In its place stood something that should not exist.
It was tall. Too tall. Its skin was the color of bruises, its mouth a vertical slash filled with needle teeth. It had no eyes—only hollow sockets that somehow saw him anyway, tracked him, hungered for him.
"Son of Death," it hissed, and its voice was a thousand dying breaths. "We smell you."
The diner erupted.
The trucker was already gone—vanished, like he'd never existed. The old woman too. Yannis stood frozen at the grill, spatula in hand, eyes wide and uncomprehending. The creature lunged.
Chai moved on instinct.
He didn't run. He didn't scream. He threw himself sideways, flipping over a booth, landing in a crouch that should have shattered his knees. The creature's claws tore through vinyl and foam where he'd been standing.
"What the hell—"
"You don't know?" The creature laughed, wet and wrong. "You really don't know?" It circled him, unhurried now, savoring. "Your father is death itself, little godling. And you? You are the knife they've all been waiting for."
"My father—"
"Thanatos." The creature lunged again. "God of peaceful death. Your father. And every god in every realm wants you dead."
Chai's back hit the wall. No more room. No more time. The creature's jaws opened wide enough to swallow his whole head.
And something snapped.
Not in the creature—in him.
The cold that had lived in Chai's chest his entire life exploded outward. The air temperature dropped thirty degrees in a heartbeat. Frost spiderwebbed across the walls. The fluorescent lights flickered, popped, died.
The creature screamed.
It stumbled backward, clutching its face. Where the cold touched it, its skin crumbled—flaking away like ash, like dried leaves, like things that had been dead a very long time.
"Stop," it begged. "Stop."
Chai couldn't stop. He didn't know how. The cold kept coming, kept pouring out of him, and the creature kept crumbling—
A hand clamped onto his shoulder.
Chai spun, cold lashing out—
And stopped.
The man behind him was tall. Dark-haired. Dressed in a suit so black it seemed to drink the light. His eyes were the color of dying embers, and when Chai's cold touched him, he didn't flinch. Didn't crumble. Didn't even blink.
Instead, he smiled.
"Easy, boy," said Hades, King of the Underworld. "That one's already dead. No need to kill it twice."
Behind him, the creature collapsed into a pile of gray dust.
Chai stared at his own hands. At the frost still curling from his fingertips. At the man who should not exist, standing in a ruined diner, looking at him like he'd been looking for him his entire life.
"Who," Chai whispered, "what am I?"
Hades's smile widened.
"That," he said, "is a very long story. And we have very little time." He glanced toward the door. Outside, the sky was wrong—too dark, too thick, full of things moving. "They've found you now. More will come. Stronger ones. Hungrier ones."
"Who?"
Hades met his eyes.
"Everyone."
