" outskirts of these volcanic cavern fringes." Aren't "fringes" and "outskirts" redundant in this sense? Why not be more specific?
"rouge population" It's yellow, not rouge. You meant "rogue".
"gasses"
"octthermas" Octhermas.
This is a very creative use of the Water Table environment. I didn't even know about volcanic aquifers until now, and I knew very little about water table interactions with magma. (I knew about geysers, of course, but my knowledge was incomplete.) Blending water table organisms with the hydrothermal vents somewhat may allow for a greater variety of organisms.
I also like its new body shape and drastically different color.
