The following account was recorded in the agent's log during your transmission: Gnarly crystalline spires are jutting out of the ocean floor around me, Echo... sunlight barely penetrating the depths of this part of the trench, but a diffuse blue glow's radiating from the crystalline structures themselves, illuminating weird, geometrical sea anemones that seem to be, like, mirroring the shapes of the crystals. The air - or water, rather - pressure's insane down here, and the smell's like... copper? A small, perfectly circular section of the ocean floor nearby has zero gravity, with pebbles and debris just hovering motionless in mid-water.
