The following account was recorded in the agent's log during your transmission: Massive, crystalline stalactites are hanging from the ceiling of this underwater cave, reflecting the faint sunlight filtering down from above. Uh, the water's perfectly still, with no current or ripples, and it's like, not cold at all, more like lukewarm bathwater. Schools of bioluminescent fish are darting past the stalactites, leaving behind trails of tiny, shimmering particles that somehow form perfect, cursive sentences in mid-water, like they're writing some sort of underwater diary. The air pressure's extreme, but somehow, a small, intact, vintage-style door is standing upright on the cave floor, complete with a shiny brass doorknob.
