The split sky lingered for days, a wound that refused to close.
Half of it burned gold, half black as obsidian glass. The world beneath had learned to live in that twilight—one side of every shadow brighter, the other darker. Rivers glowed faintly at night, and whole valleys flickered like candlelight trapped between breaths.
At the center of it all stood Hollowspire.
Once radiant, the tower now pulsed fitfully, its light faltering like a heart on the edge of collapse. The hum that had filled the valley had turned into a grinding murmur, the song of two opposing rhythms forced to share a single body.
Aric felt it constantly. Every heartbeat echoed wrong. Every breath burned cold and hot at once. The mark of darkness that had begun on his left palm now webbed halfway up his arm, the veins black and gold twining like roots at war.
He could no longer tell which voice whispered first—the Core's warmth or the Hollow's patient hunger.

Eira stood at a workbench beneath the spire, surrounded by flickering crystals and cracked resonance lenses. The air smelled of burnt ozone. She hadn't slept in two days.
"The lattice keeps reversing," she muttered, scribbling notes that trembled from the tower's vibration. "Every flow of resonance gets drawn inward. It's trying to fold the whole system back into the Heart."
Brann leaned against a column, arms crossed. "Then we're sitting on the mouth of a beast that's about to swallow us."
Eira glanced up at Aric, her eyes ringed with exhaustion. "The Hollow's burrowing beneath the mountain. It's going for the Core's central Node—the same one the Concord sealed a thousand years ago. If it reaches that, it won't just unmake this valley. It'll unmake everything."
Aric looked up toward the quivering ceiling. The tower's hum had changed pitch—no longer a song, but a pulse. "Then that's where we go."
Eira straightened. "Aric—"
"I have to see it. The world's breaking from the inside, and I'm the fracture."
Brann gave a weary grin. "Then let's plug the hole before it eats the rest of us."
---
They left that night. The Faithbound remained outside, campfires dotting the valley like stars reflected on the ground. Kaen met Aric at the spire's entrance, his armor veined with light and shadow alike.
"The faithful grow restless," Kaen said. "Some believe you can heal the world. Others think you are the world."
Aric studied him. "And you?"
Kaen smiled faintly. "I believe the gods envy you."
Eira's voice was sharp. "He's not a god."
Kaen's eyes flickered. "Not yet."
He turned away before Aric could answer.
---
The descent began through the spire's lower chambers—tunnels carved from crystal that pulsed dimly underfoot. The deeper they went, the slower the world seemed to move. Shadows stretched. Time thinned. Words came late, as though the air itself hesitated to carry them.
By the third mile, the walls began to breathe.
Veins of gold and black light ran through the crystal, expanding and contracting in rhythm with Aric's pulse. The tunnel bent in impossible ways—descending, ascending, folding over itself. Once, Eira looked back and saw their footprints trailing upward across the ceiling like constellations.
Brann broke the silence. "Feels like we're walking through someone's memory."
Eira's tone was brittle. "We are. The Core built this place from resonance echoes—it remembers every step we take."
Aric felt it too. With every breath he heard faint whispers—fragments of his past and others', tangled in the hum. A child laughing. A scream. The shattering of glass.
Then the tunnels widened into a chamber that made the air vibrate. The floor was black glass, reflecting not their bodies but moments—each footstep flashing with visions of what had been.
Eira gasped. "It's replaying us."
She turned in time to see a ghostly image of herself sealing a containment vault years ago, tears streaking her face. "That's not possible."
Brann saw beasts from old hunts—each kill played backward, the wounds closing, eyes opening. His hands trembled. "They remember me."
Aric looked down and saw his mother kneeling beside him as a child, pressing a shard of glass into his hand, whispering: All light forgets the dark that made it.
He flinched, the memory collapsing into smoke.
Eira caught his arm. "They're echoes, Aric. Don't let them anchor you."
He nodded, but his voice was distant. "It already has."
---
The path narrowed again, twisting into a spiral that led to a single door of living crystal. It pulsed like a heartbeat, half gold, half black.
Beyond it, they felt power so immense it silenced thought.
"The Heart," Eira whispered. "The center of the Core."
The moment Aric touched the door, it dissolved into light, revealing a cavern beyond—a vast hollow the size of a city.
At its center floated the Heart Beneath the Hollowspire: a sphere of crystal as wide as a mountain, split down the middle, one half glowing brilliant white-gold, the other a void so deep it seemed to drink the world. Energy arced between the halves, lightning frozen mid-strike.
The hum became unbearable. Light and shadow pulsed out of sync, tearing rifts in the air that revealed glimpses of stars, oceans, faces. The sound was not music—it was existence arguing with itself.
Eira stumbled back, shielding her face. "It's alive!"
Brann shouted over the roar. "Then let's kill it before it notices us!"
Aric stepped forward. The marks on his arm blazed, black and gold flaring in unison. "No. This isn't the enemy."
Eira grabbed his sleeve. "Aric, you can't—"
He looked at her, and for a moment his eyes were mirrors, reflecting both her fear and the light of the Heart. "It's calling me."
Then he walked into the light.
---
The roar ceased.
Aric found himself standing in an endless expanse of still water, sky and ground identical, both reflecting the other. A soft wind stirred.
Figures appeared in the distance—tall, faceless shapes woven from resonance, each holding a fragment of the Heart. They spoke without voices.
We were the Makers. We shaped the Core to preserve what was good and sealed the Hollow to bury what we feared.
Their forms flickered, dissolving into memory.
But in binding one, we bound both. The wound of creation could not heal. So it made a guardian to hold the balance.
Images flashed: cities of light collapsing into shadow, oceans rising into the sky, beasts dissolving into sparks. The cycles repeated endlessly. In each, a single figure stood between light and dark—a man, a woman, sometimes neither—each sharing Aric's face.
You are the echo of that first guardian. The seal's memory reborn.
The water darkened beneath him, half glowing, half void.
You cannot destroy us. You can only choose which song to end.
Two shapes rose before him—one radiant, the other hollow.
The Core spoke, its voice like sunlight through glass: Embrace me and the world will endure. All will live as one. No more hunger. No more fear.
The Hollow answered, soft and infinite: Embrace me and the world will sleep. No more struggle. No more pain.
Their words echoed in him, filling every space until he could no longer tell which was mercy and which was death.
He saw the futures they offered:
A world of light where everything breathed the same song—no predators, no prey, only harmony. But there was no freedom. Nothing changed. Everything lived forever, and nothing truly lived.
A world of shadow where everything ended in peace—no suffering, no loss. But there was no memory. Nothing loved, because nothing remained to remember.
Eira's voice reached him through the darkness. "You don't have to be either. Be human!"
---
He opened his eyes. The two halves of the Heart pulsed before him, waiting. His reflection split across them—one side gold, the other black.
He placed a hand on each.
The chamber exploded with light and void. Power surged through his veins, tearing his body apart and knitting it back together in the same instant. The Core screamed. The Hollow wept. Their voices merged into one sound that transcended language—raw existence.
Aric cried out, the sound swallowed by the storm. His bones glowed, his skin turned transparent. The mark on his arm spread across his chest until half his body was darkness, half fire.
You cannot hold both, the voices thundered.
He shouted back, "I already am!"
The Heart shuddered. The cavern cracked. Energy tore upward through the mountain, splitting Hollowspire's tower open to the sky. Above, the crack in the heavens widened, light and shadow twisting into a spiral that stretched from horizon to horizon.
Outside, Kaen's army fell to their knees. The Faithbound wailed prayers as the spire blazed, half brilliant, half void. The air filled with petals and ash.
---
Inside, Eira fought through the storm, shielding her face from waves of light that burned and healed all at once. "Aric!" she screamed. "You'll die!"
He turned to her, smiling through blood and light. "Maybe that's what balance means."
He slammed both hands against the Heart.
A single pulse rang out—one so deep it shook continents.
The light flared, the shadow deepened, and for a heartbeat both became the same color—something beyond either gold or black. The air went silent. Then everything broke.
The mountain convulsed. The spire above exploded outward, shards of crystal raining down as far as the ocean. From the crater rose a column of pure resonance—half warmth, half cold, spiraling into the sky like a new sun.
Eira dragged Aric's body from the rubble, coughing through the smoke. His chest glowed faintly, veins alternating colors like breath. Around them, the world began to shift.
The Faithbound's forms flickered—some dissolving into light, others collapsing into dust, still others reborn with luminous eyes. The beasts of the valley howled in both agony and ecstasy. Rivers reversed again, now shining with gold and ink.
Brann stumbled out of the debris. "What did he do?"
Eira looked at the sky. "He didn't choose."
---
When Aric awoke, the world was quiet.
He lay at the edge of the crater where the Heart had been. Above him stretched a sky unlike any he'd ever seen—half sun, half night, both eternally present. The air shimmered with impossible color.
Eira knelt beside him, smiling through tears. "You're alive."
He touched the ground. It pulsed faintly under his palm—neither warm nor cold, but both. "So is everything else."
Brann stood nearby, looking around in awe. "Is it over?"
Aric sat up slowly. The glow in his eyes flickered between gold and shadow. "No. It's begun."
He looked toward the horizon, where the world was already reshaping itself—mountains growing from plains, oceans draining into new chasms. Creation and erasure, side by side.
He smiled faintly. "The wound finally stopped bleeding. Now it's learning to scar."
Eira reached for his hand. It was warm and cold at once. "What are you now?"
Aric looked toward the broken sky.
> "Balance," he said. "Nothing more. Nothing less."
And as the wind carried the scent of both ash and blossom, Hollowspire rose anew—a spire of twilight crystal, half light, half shadow, beating with a single, steady pulse.
> And for the first time since the world was born, creation learned to bleed.
