The Citadel's gates screamed open—not with sound, but memory.
A tidal wave of forgotten noise crashed into Kael's mind: forgotten Earth languages, sirens, laughter, prayers whispered by the last survivors of a planet on the edge. His body remained still, but his thoughts swirled like stormwater.
They entered.
No turning back now.
The inside was impossible geometry—walls folding inward, staircases leading nowhere, mirrors that reflected futures that never came. The ground beneath them was cracked obsidian, veins of pulsating white-blue energy threading through the stone like nervous system roots.
Zarith gasped. "This place isn't built—it's remade. It rewrites itself every time someone steps inside…"
"It's alive," Tessia said, her silver eyes flickering. "And it's judging us."
Dren glanced around, hand on his sword. "I've fought in a hundred kinds of hell. This is new."
At the heart of the chamber, a spire floated—twisting upward with no visible support, covered in glyphs from Earth, Exarune, and… another language none of them recognized.
Kael stepped closer. His shard flared in his palm, drawn forward like a magnet.
The Citadel spoke again.
"You seek the Obsidian Axis."
"You seek the Thread that Binds All Ruins."
"One of you is marked. One of you is unworthy. One of you will shatter."
Sera narrowed her eyes. "It wants us to turn on each other."
Kael didn't blink. "Ignore it."
But the room began to split—literally fracturing into five paths, each leading away into a different version of reality.
"Walk your truths," the Citadel whispered.
"Or be broken by them."
Each team member was pulled into a different corridor.
Kael's corridor was dark.
Not just in light—but in meaning.
The world flickered… and changed.
He was back in Earth's ruins.
No powers. No runes. No pulse.
Just his old body. Caelum Veras.
Alone.
And walking toward him was a figure made entirely of fractured timelines—a fusion of what he could have become. A broken god. A tyrant. A corpse on a throne. A child begging for meaning.
Each step it took, Kael felt weaker.
It stopped inches away.
"You're not supposed to exist," it said, with his voice.
"You broke recursion."
Kael stared at himself. "No. I broke the game."
And he moved—not with power, but precision.
One strike to the jaw. One word to unravel a memory. One thought to collapse a paradox.
The figure shattered into dust.
The darkness faded.
And Kael stood in the center of the spire again—alone, but stronger.
One by one, the others returned.
Tessia walked out with claw marks across her arm but burning eyes.
Dren emerged with tears on his cheek, but his blade brighter than ever.
Zarith looked hollow—but stable. Sane, for now.
Sera came last, clutching a memory crystal of her dead squad… and smiling for the first time.
The Citadel pulsed.
"You have walked your paths."
"Thread-Sync complete."
"The Obsidian Axis accepts your passage."
From the center of the Citadel, a new ruin opened—a gate of crystal and steel, leading elsewhere.
Kael held up the shard, which now pulsed like a heartbeat made of starlight.
"This is it," he said. "The Axis connects all ruins. All timelines. It's the spine of Exarune."
"And beyond it?" Tessia asked.
Kael looked forward, eyes calm.
"Earth. Rewritten."
He stepped through.
