The following account was recorded in the agent's log during your transmission: Massive crystal formations are embedded in the rough, basaltic rock walls of a colossal volcanic cave. Umm, the air's charged with static electricity, making my hair stand on end, and it smells heavily of sulfur and burned fuel. Shafts of sunlight filter in through a series of small openings in the cave ceiling, illuminating weird symbols carved into the crystal formations - like, they seem to match some sort of encrypted message from Cicada 3301. A dense, slow-moving river of what looks like pure mercury flows silently through the center of the cave.
