The following account was recorded in the agent's log during your transmission: The air's got this weird, uh, coppery taste, and it's pretty still, heavy with the smell of... ozone-free air, I guess, like after a rain. I'm surrounded by what looks like a massive, naturally occurring, perfect icosahedron crystal cave, with these slow-moving, etched fractal patterns from ancient Platonic geometry merged with the living mycelium networks covering the crystal faces, and they're subtly responding to... some invisible pressure. The sunlight filtering through is casting a miniature, inverted representation of a Möbius strip on part of the crystal floor. A chunk of Antarctica's ice sheet is just embedded here, seamlessly merged with the crystal lattice.
