The following account was recorded in the agent's log during your transmission: Umm, a large, pretty empty, indoor swimming pool is sitting in the middle of a vast, open cavern, and the air's pretty damp and musty. Like, the only sound is the gentle lapping of the water against the sides of the pool and some distant dripping noises. A bunch of otters are swimming around and somehow the water level is staying exactly the same, despite the pool having no visible bottom or sides to hold the water in place. The air's pretty still, and it's probably mid-morning judging from the soft, diffused light filtering down through the cavern.
