The following account was recorded in the agent's log during your transmission: Uh, frozen stalactites are suspended mid-air in this vast, subterranean cavern, their fragile tips inches from the glacial ice that's slowly creeping across the stone floor like a tide. Shards of shattered stained glass, still radiating an otherworldly resonance, are embedded in the ice, casting kaleidoscope patterns across the rough walls. Air's biting cold, heavy with the scent of myrrh, and it feels charged with static electricity – I can see sparks leaping from the glass shards to the cavern walls. Above, a miniature aurora borealis is pulsating, seemingly drawn to the symbol etched into the frozen lake's surface.
