The following account was recorded in the agent's log during your transmission: Fractured sunbeams punch through a crystal-encrusted skylight, casting kaleidoscopic patterns across an endless dune sea of iridescent powder within a hollow, kilometer-long cylinder... air's super-dry, metallic, and tastes like burned circuitry. Uh, crystal shards are being expelled from the walls, etching Minoan hieroglyphs into the floor – those match the spiral on that ruined fresco at Akrotiri. The dust below is being shaped by invisible hands, sculpting geometric basins that reflect distorted constellations and hold tiny whirlpools of quicksilver... still no idea what the hell I'm seeing, Echo... you gotta keep moving.
