The following account was recorded in the agent's log during your transmission: A crescent-shaped lake of churning mercury sits within a cavernous, crystalline cave, its mirrored surface reflecting a twisted latticework of glittering, quartz formations. Umm, the air's crisp, electric, like right before a storm, the smell of ozone and damp stone hanging heavy. A spiral-shaped waterslide made from what appears to be polished obsidian somehow curves upward, defying gravity, before vanishing into the crystal-studded ceiling. In the distance, the sound of softly chiming glass harmonicas echoes through the cavern, their melody somehow affecting the local gravity – causing small ripples on the lake's surface to momentarily pause mid-splash.
