Arden dreamed of doors.
Not ordinary ones, but thresholds carved from riblike arches and veined with pale light, each pulsing faintly like something alive was waiting behind them. Every door whispered his name in a cadence that felt rehearsed, as if the universe had practiced calling him long before he existed.
He tried to reach the closest one, but the floor beneath him shifted. Bone turned to mist. Mist hardened to stone. Stone cracked into sand. The world rearranged itself each time he dared to blink.
A voice somewhere in the shifting haze murmured, "Second breath…"
He jolted awake.
The Warden's chamber materialized around him, dim and quiet, lit by drifting motes that looked like softened starlight. Nyra was perched nearby, sharpening her blade with the kind of focus that meant she was trying not to think too loudly.
"You were muttering in your sleep," she said without looking up.
"Dream," Arden murmured, sitting up. "Or something pretending to be one."
Before Nyra could respond, a soft metallic groan echoed through the chamber. The Warden entered slowly, carrying the Bone Lantern in both hands as if he were afraid the thing might leap away.
The pale cage glowed from within, brighter than before, and the crack on its surface spidered just an inch further.
"It's accelerating," he said.
Arden instinctively stood. "Because of the… ashes?"
"Because they recognized you."
Nyra paused mid-motion, finally lifting her gaze. "Recognized what, exactly?"
But the Warden didn't answer her. Instead, he stepped closer to Arden and lowered the Lantern until its faint breath-like pulse matched the rhythm in Arden's chest.
Both glows synchronized.
Nyra's eyes widened. "It's resonating with him."
"No," the Warden said quietly. "It's testing him."
Arden felt a tug, subtle but persistent, like something inside the Lantern was knocking on the inside of his ribs.
A memory not fully his flickered through him: cold water, a submerged heartbeat, a whisper urging him to inhale when he should drown.
He staggered.
Nyra caught his arm. "Arden."
"I'm fine," he lied.
The Lantern's light flickered once. Twice. Then steadied into a thin beam that extended outward, tracing the air until it pointed to a passageway at the far end of the chamber that none of them had seen before.
A narrow archway of bone, freshly revealed, as if the cathedral itself had pulled aside a curtain.
The Warden stiffened. "It's opening the pathway already? That shouldn't happen until—"
Arden finished for him. "The second breath."
Nyra stepped between Arden and the archway. "We're not just walking into whatever that thing wants."
But the Lantern pulsed harder, and the newly formed arch responded with a deep vibration, almost impatient.
Arden felt the pull again, stronger this time. Something inside the corridor was calling him, not with malice or welcome, but with inevitability.
The Warden bowed his head. "The Lantern chooses its bearer. Its timing is not ours to command."
Nyra bristled, her fingers tightening around her blade. "And what if its timing gets him killed?"
The Warden's voice dropped. "If he doesn't answer it… something far older may die in his place."
A wind rolled out of the archway, cold and metallic, smelling faintly of forgotten ocean depths.
Arden stepped forward.
Nyra moved with him, refusing to fall behind.
The Warden followed, Lantern in hand, its glow painting their path in sharp, ghostly lines.
As they crossed the threshold, the corridor sealed behind them with a soft, echoing click.
The Lantern brightened.
And far ahead, in the heart of the bone labyrinth, something inhaled.
Waiting for him to exhale.
