Notes:

A third Lovecraft-based one, after the Shoggoth and Atlach-Nacha.
Gotta say I still like the Shoggoth more.

They're kinda gross.
Covered in a viscous mucus.

Similar to the Mindflayers and Atlach-Nacha, their husband gets turned into a kind of monster thing that clings to them at basically all times.
Says they become weirdo tentacle creatures that replace their wings and cover them in tentacles, so I guess that one is married.

I'm always kinda leery about adding the actual encyclopedia entry, given that they tend to have a bunch of dirty talk, and I've never been clear about standards around here.
