From publisher blurb:
“Just when you thought it was safe to adventure in the water!”
Aboleth are an empire of entirely inhuman intelligences who are older, smarter, and more vile than most land-based races. This book assumes that a race as old and powerful as aboleth, and as prone to manipulating and transmogrifying other races, is going to have a great deal more in their empire than just their core race and skum servants.
We present a wide range of noisome and disquieting new threats, ready to turn their alien intellects to the destruction of the PCs’ world. So prepare to behold the behemoth, face the slime golems, and flee the tentacle crabs. Nothing can save you now.
