The following account was recorded in the agent's log during your transmission: Light's filtering through a kaleidoscope-colored latticework of crystals suspended above a sprawling, crystalline cave system, which is somehow embedded within the caldera of an active volcano. Uh, the air's thick with the scent of molten lava, smoke, and something faintly like frankincense; it's extremely hot, with waves of heat radiating from the cave walls, which are slick with iridescent, crystalline growths that seem to be slowly absorbing and redirecting lava flows. Schools of bioluminescent, flying creatures are weaving through the crystals, leaving trails of glittering, micro-crystalline shards in their wake, which then disintegrate and reassemble into miniature, functional replicas of Metatron's Cube. It's like, mid-afternoon, with the sun directly overhead.
