I pulled myself free from the gap in the rubble, my fingers scraping against stone that still held warmth from Blair’s earlier Hellflame treatment.

The passage she’d widened before, the one that had saved us from the centipede’s mandibles, had partially collapsed during the cave-in.

What remained was a crawlspace angled upward at roughly thirty degrees, maybe thirty-five if I was being generous about the geometry.

Not comfortable by any reasonable metric. Definitely not safe by any interpretation of that word. But it was passable if neither of us breathed too deeply or thought too hard about the several thousand tons of volcanic rock balanced precariously above our heads, held up by nothing more substantial than geological inertia and what I could only assume was the universe’s dark sense of humor.

"I can feel airflow," Blair said from behind me, her voice stripped of everything except information. The version of Blair who had kissed me, who had wrapped her legs around my thigh and whispered her hatred like a love letter, had already been packed away into whatever compartment Blair stored things she refused to acknowledge.

"Temperature differential suggests an opening within forty meters. The rock composition shifts from basalt to something with higher quartz content approximately twenty meters ahead, which means the strata here are fractured naturally rather than from the collapse."

I glanced back at her. She was already army-crawling into the gap behind me, her elbows finding purchase on stone that glowed faintly blue from residual moss.

The burns on her left side pressed against the ground with every forward push, and I could see the way her jaw locked each time the contact sent pain radiating through her body. She didn’t make a sound.

"You good?"

"Don’t ask me that."

I turned and kept crawling.

The passage narrowed twice, widened once, and then angled sharply upward into something that resembled a natural chimney in the rock.

I braced my back against one wall and my boots against the other, shimmy-climbing with the kind of core engagement that three weeks ago would have been physically impossible. C-rank Strength made the movement manageable.

The wounds across my chest protested every flex of my torso, and the mana corruption from the leopard’s claws sent cold spikes through my ribs whenever I twisted. I kept climbing.

Below me, Blair followed. Her technique was different from mine, more efficient in the shoulders and less dependent on core stability, the kind of climbing form that came from private instruction rather than desperation. Her breathing stayed controlled through a pattern that sounded almost meditative, four counts in, four counts out, each exhale timed to her body’s forward push.

She climbed like someone who had been trained to climb, which she probably had, because Davenport Industries didn’t produce children who couldn’t scale corporate ladders or literal ones.

The chimney opened into a horizontal passage wide enough for me to crawl on hands and knees. The air here tasted different. Cleaner. Less dense with the mana saturation that had turned the main cave system into a pressure cooker.

My Sensory Hijack registered a temperature gradient ahead, warmer air from outside mixing with the cooler subterranean atmosphere. The bioluminescent moss grew thicker along the walls, casting enough light that I could see the passage curving to the right before opening into something with real height.

I emerged into a space that made me stop breathing.

The cavern extended in every direction like someone had hollowed out the inside of a mountain and forgotten to tell physics.

The ceiling rose a hundred feet overhead, covered in bioluminescent moss so dense and bright it approximated a sky, casting the entire space in deep blue light that made everything look like a scene from an underwater documentary.

Stalactites hung from the roof like inverted skyscrapers, some of them twenty feet long, dripping mineral-rich water that collected in pools across the uneven floor.

The pools themselves glowed from within, the water carrying dissolved mana crystals that turned each basin into a small lamp.

Between the pools, the floor was smooth volcanic glass, polished by centuries of water flow into a surface that reflected the blue light like dark mirrors.

And in the center of the cavern, sitting on a raised platform of naturally formed quartz, was the core.

I knew it immediately. Not because of Treasure Sense, which I’d swapped out for Reaper’s Edge during the alpha fight.

Not because the System provided a helpful notification, though it did, a terse CORE ENTITY DETECTED flashing in my peripheral vision before disappearing.

I knew because every cell in my body recognized the thing for what it was. The heart of the Void Gate. The reason the dimensional seal held.

The reason the forest existed, the leopards hunted, the centipede burrowed through solid rock, and ten first-year students found themselves trapped in a space that should not exist.

The core looked like a crystal the size of a beach ball, suspended three feet above the quartz platform with no visible support.

It rotated slowly, its surface cycling through colors that didn’t belong in any spectrum I’d seen before: deep purple bleeding into gold, gold dissolving into black, black igniting into white that hurt to look at directly.

The light it cast was warm rather than blue, creating a circle of golden illumination around the platform that contrasted with the cool bioluminescence of the rest of the cavern.

Blair emerged from the passage behind me and stopped.

"That’s it," she said.

"That’s it."

The cavern felt empty. No hostiles registered on my senses, no thermal signatures through Sensory Hijack, no ambient sounds beyond the dripping of mineral water and the low, resonant hum of the core itself. The hum existed below hearing, a vibration I felt in my molars and sternum rather than my ears.

"Where are the guards." Blair’s voice was flat. A statement rather than a question.

"Good question."

We stood at the passage entrance for a full minute, both scanning the cavern with our respective abilities. Blair’s thermal sense swept the space in expanding arcs. My Sensory Hijack probed the shadows between stalactites, the depths of the glowing pools, the dark alcoves where the cavern walls curved into unseen recesses. Nothing. The space appeared completely, impossibly empty.

"This is wrong," Blair said.
