The following account was recorded in the agent's log during your transmission: Sunlight barely reaches down here, filtering in from above through the murky, algae-choked water, casting a weird, greenish haze on the rough stone walls of... a massive, submerged canyon system. Umm, the water pressure's crushing, and the air's stale, kinda... heavy, like it's hard to breathe, but somehow, a delicate, ceramic tea set sits undisturbed on a flat rock outcropping, not a single cup out of place, no sediment or anything. A faint tremor runs through the stone, like the whole place is... shifting, and a section of the canyon wall just sorta... isn't, like it's been neatly cut out with a scalpel.
