As Johan delved further into the depths, he came across an unexpected spectacle. The tunnel widened abruptly into an expansive cavern. Instead of the earthen tones of stone and dirt he'd grown accustomed to, this cavern was a kaleidoscope of shimmering crystal.
The walls, floor, and ceiling were made of pristine, multi-faceted crystal, each surface gleaming with its own internal light. 'An oasis of light in this abyss,' he mused. It was disconcertingly beautiful, the ethereal glow lending an otherworldly atmosphere to the cavern.
The countless crystal facets reflected his image, creating an army of doppelgangers. The illusion of space was distorted by the mirror-like properties of the crystal. 'Left could be right, up might be down,' he thought. His gaze was drawn to his multiple reflections, their combined scrutiny unsettling.
