From publisher blurb:
Volume Three features eight creatures and variants, including the headless acephali, a race of monstrous humanoids with their faces in their chests; the lemurians, a lost branch of humanity with unique adaptations for their men and women; the oklod, strange creatures deserve strange riding beasts, and the crustacean oklod fits the bill; the synaltren, a horrible two-headed reptile that drains heat with one breath weapon in order to spew it with the other; the emulock template, once constructs of order these mechanoid imitations of ordinary creatures have fallen into chaos; and the slythh, a race of outsiders that manifested the ultimate chaotic mutation: an orderly nature, and spun off from the realms of chaos.
As a bonus, this PDF includes write-ups for two demi-planes: Tumultus (home of the emulocks) and Assymbex (home of the slythh).
