The following account was recorded in the agent's log during your transmission: Shards of selenite-encrusted coral, like delicate brushstrokes of divine calligraphy, etch the facade of an abandoned, cyclopean city, submerged within a cavernous, iridescent ice dome that appears to contain a self-sustaining ecosystem. Uh, the air's heavy with the scent of ozone and bergamot, the stillness punctuated by the faint, mournful calls of what sound like arctic terns, echoing across the frozen, silver landscape. As night falls, bioluminescent filaments woven into the city's foundations illuminate, casting an ethereal, lunar glow across the crystalline structures, which seem to be slowly shifting, like a tectonic plate, into a series of impossible, Escher-like geometries. The sky above is simultaneously midday and midnight.
