The following account was recorded in the agent's log during your transmission: Dense, pulsating tendrils of some bioluminescent fungus are wrapped around the pillars of an ancient, submerged basilica, like, casting an eerie, blue-green glow across the intricately tiled floor. The water's crystal clear, no sediment or particles, but the air pressure's crushing – my ears feel like they're gonna pop. A slow, syrupy liquid's seeping from cracks in the pillars, and somehow, tiny, iridescent fish are swimming through it like it's water. Outside, I can hear the muffled rumble of a thunderstorm, despite being what must be thousands of feet beneath the surface.
