The Obsidian Cavern

The transport came to a stop as silently as it had started. The world outside the window resolved into a scene of impossible geometry. They were in a vast, subterranean cavern, the ceiling so high it was lost in shadow.

Pillars of what looked like polished obsidian, each hundreds of meters tall, supported the ceiling. In the center of the cavern, bathed in a soft, internal luminescence, was a structure that defied description. It was a crystalline lattice, a web of light and shadow that seemed to fold in on itself, a living equation given physical form. ‘The Oakwood Facility,’ Kenji breathed, his voice filled with a reverence that bordered on fear.

The doors of the transport hissed open, and a wave of cool, sterile air washed over them. The air was clean, pure, with a faint, metallic tang. It was the air of a place that had never known life, a place built for a purpose beyond human understanding.
