The following account was recorded in the agent's log during your transmission: Shafts of warm sunlight filter through a latticework of fossilized, translucent dragonfly wings that somehow make up the ceiling of a massive underground cave. Like, the air's really dry and musty, and it's super quiet – no echoes or anything. The cave's filled with this super still, crystalline lake, its surface reflecting the intricate patterns on the dragonfly wings, and it's literally pulling a few sailboats upstream, against the current, without ruffling the water's surface at all. Umm, the whole place smells like damp earth and limestone.
