The silence didn’t last.
Eren barely had time to catch his breath before the crystals along the chamber walls flickered. Their pale blue light dimmed, then shifted—stretching and warping until shadows pooled unnaturally across the floor.
The Core pulsed once.
Hard.
Eren froze.
Something was wrong.
The remains of the creature at his feet began to dissolve, breaking apart into blackened fragments that sank into the stone like ash into water. The temperature dropped further, cold seeping into his bones.
Then the shadows moved.
Not drifting.
Crawling.
They peeled themselves away from the walls, stretching into thin, humanoid shapes with no features—no faces, no eyes, only jagged silhouettes that writhed as if alive.
Eren stepped back, heart hammering.
“This… is the trial?”
The answer came in the form of pressure.
The air grew heavy, pressing down on his shoulders, forcing him to his knees. His muscles screamed as he fought to stay upright, the Aether Core flaring in response. Heat surged through his chest, pushing back against the weight.
Trial condition active.
Objective: Endure.
Endure?
Eren clenched his teeth.
The first shadow lunged.
Stolen novel; please report.
He rolled aside just as a claw of darkness slammed into the ground where his head had been. The impact cracked stone, leaving behind frost-like scars of black energy. Eren scrambled to his feet, instincts screaming.
These things weren’t physical—not fully.
His knife passed through the second shadow with little resistance, the blade slicing through mist and darkness alike. The creature shrieked, its form destabilizing, but it didn’t fall.
It adapted.
The shadows shifted, growing denser, their outlines sharpening. What little light remained was swallowed almost entirely.
Eren’s breath came fast.
Think.
The Core pulsed again, slower this time, syncing with his heartbeat. His vision sharpened, faint lines appearing once more—threads of energy weaving through the chamber, connecting the shadows to the crystals in the walls.
“They’re feeding on the ruins…”
Understanding struck.
If he couldn’t defeat them directly, he had to break the source.
Eren ran.
A shadow intercepted him, slamming him hard against a pillar. Pain exploded through his shoulder as he hit the ground, stars dancing across his vision. Cold crept along his arm, numbness spreading.
“Move… move!”
He forced himself up, ignoring the pain, the Core blazing hotter with every step. The pressure intensified, the trial responding to his resistance.
Aether output increasing.
Warning: Core instability detected.
Eren skidded to a stop beside one of the glowing crystals. Up close, he could feel it—raw energy thrumming beneath the surface, chaotic and unstable.
He raised the knife.
“Let’s see what happens.”
The blade struck.
Blue light erupted as the crystal shattered, sending a shockwave through the chamber. The shadows shrieked in unison, their forms unraveling like smoke in a storm.
Eren was thrown backward, hitting the ground hard.
The pressure vanished.
Silence returned.
Eren lay there, staring at the ceiling, chest heaving. Slowly, warmth spread through his body—not the frantic surge from before, but something steadier. Controlled.
The Aether Core pulsed gently, as if… satisfied.
Faint symbols appeared in his vision, clearer this time.
Trial complete.
Shadow Affinity detected.
New Skill Available.
Eren sat up sharply.
“Shadow… affinity?”
The thought barely formed before a ripple passed through the air around his hand. Darkness bent—not disappearing, but responding, folding inward like a living thing.
His breath caught.
This wasn’t just survival.
This was evolution.
But even as the realization settled in, the ruins responded.
Deep within the structure, something shifted.
A low, distant sound echoed through the corridors—slow, deliberate, and far heavier than anything he had faced so far.
Eren looked toward the darkness ahead, the Core pulsing with equal parts anticipation and dread.
The trial was over.
The real danger was waking up.
