The following account was recorded in the agent's log during your transmission: Rain pours down around crystalline obelisks that sprout out of the seafloor like giant shards of glass. Umm, the sunlight filtering down through the water is casting these shimmering, rainbow-colored patterns all over the sandy seafloor, and I can hear this weird, pulsating hum that's somehow not disturbing the schools of bioluminescent fish swimming around the obelisks. The air pressure's extreme, but the water around the obelisks is somehow behaving like a solid, creating these perfect, cube-shaped bubbles that just sit there, not rising or falling, just... stuck. The water smells like salt and something faintly metallic.
