The following account was recorded in the agent's log during your transmission: The entire space is an empty Olympic-sized swimming pool under super bright, midday sun – gotta squint, hurts my eyes, Echo... Umm, concrete beneath is totally dry, not a drop of water, and the air is weirdly still, except for, like, these four massive industrial air handlers embedded in the surrounding walls just cranking out this ridiculously dry air. Air handlers aren't moving but they're producing this ear-shattering, jet-like roar while pool lanes are suddenly and inexplicably shifting and reforming themselves into perfect replicas of ancient European cathedral floor plans, just out of nowhere.
