The following account was recorded in the agent's log during your transmission: Water's trickling out of a bunch of giant, hollowed-out stalagmites, like... forming this huge, crystalline network that stretches across the entire cave floor. The air's got a crisp, mineral taste to it, and the smell of damp earth is pretty strong – the pale yellow light coming from somewhere in the cave is casting these intricate, fractal patterns on the stone walls. For some reason, a massive, stone door in the center of the room is sealed with what looks like still-warm, partially molten lava, even though the air's pretty chilly.
