Marcus stood at the center of the altar, boots anchored to the hard, ink-black plaza as he watched the shifting perimeter. Mist moved with calculated intent just beyond the sharp circle of white light.
Hundreds of them.
Ember-eyes flickered in and out of the gray veil, like dying coals in a forgotten hearth. The Hounds had stopped lunging after their frantic first rush. They stalked the edge of the light with silent, predatory patience, thin ribbony bodies melting into fog until only their eyes remained. Far beyond them, the sentient presence in the deeper shadows watched through the columns, its dying-star gaze fixed on Marcus. They were waiting for the beacon to fail. The environment grew hungry around them, a physical trap that had waited eons for someone to enter its jaws.
Marcus looked down at his left hand, and his breath hitched.
The Shattering-Sigil on his palm tuned itself to the massive monolithic slab at the center of the plaza. He could feel the geometric lines beneath his skin shifting, vibrating at the exact heavy frequency of the black stone beneath his feet. Two hard jolts traveled through him. Internal neural friction vanished, replaced by a cold, numbing resonance that locked his hand to the Spire's foundational architecture like a key turning in an ancient vault.
Taryn scrambled toward him on hands and knees, patchwork leather armor clattering. The ache in Marcus's ribs tightened as he turned. She stared at his glowing palm, then at the pillar of light soaring into the lightless ceiling.
"Light fractures," she gasped, hope cutting through the weight of the room. "Marcus, the riddle. It isn't just a warning about the environment. It's an instruction. The Shattering-Sigil is unlocking a divine beacon. The tower tests your calibration. If you can hold the flow together without burning out, this light must lead to the upper floors. It must lead to the summit. To the Wish."
She reached toward his glowing wrist. The fierce mask of the elite climber had dissolved, leaving a desperate longing to save her dying world.
"It must. If this beacon can punch through the Threshold, we can get back to the higher tiers. We can stop the decay in Aetheris."
Marcus did not voice the cold, clinical truth his investigator's mind had deduced. He could read the circuit now. The beacon was a vacuum, not a gift or merciful exit. The Spire drank every ounce of energy they spent: each alchemical spark Taryn threw, every portal Lysara opened, every thread of power he channeled through his palm.
We aren't conquering a trial, he realized, keeping his face still. We are fuel. The Spire needs our struggle to keep its systems running.
He looked at the hope breaking across Taryn's face and kept the file closed. In a vertical prison where stopping meant joining the dead voices of the Choir, despair was a lethal liability.
He narrowed his focus and restricted the Shattering-Sigil's channel through muscle memory. The biting heat held at his wrist. He stayed on the safe side of the line.
"Hold onto that." Marcus kept his eyes on the layout. "But watch the pattern. The Spire isn't done filtering us."
Ice-cold agony tore up his arm.
He choked back a cry and clutched his wrist as the sigil recalibrated. The blue light narrowed into a line aimed at the ceiling. At the same time, the Nameless Choir's wayward chanting sharpened into a frantic screech that vibrated through his teeth.
The divine beacon began to hiss. Black cracks spread across the white pillar of light.
"Stars fall," Marcus whispered, the second half of the riddle resolving with forensic clarity.
He looked past the monumental, ribcage-like pillars into the dark overhead. The ceiling fractured. Colossal blocks of brutalist masonry and jagged crystal shards tore free from the void and descended toward the plain like dying meteors.
Ember-eyes flared with ravenous brilliance. The Hounds knew. The light was failing, the sky was collapsing, and the hunt was about to resume.
"Lysara! Taryn! To the dead zones behind the columns!" Marcus roared, drawing his twin daggers as his body cut left with practiced speed. "The ceiling is coming down! Follow the flow and move!"
The first stone broke free overhead, revealing a blue sigil burned into the falling slab.
