Fomorian

A Fomorian is a creature shaped by magic, created by the Obsidians to serve in the Westreach Army in the Blade of the Avatar novella. It is implied that they are a newer mutation than some other monsters (such as the Satyr), and are first mentioned as existing only some time after the fall of Midras.

They have not yet made a physical appearance in the book, although an Update of the Avatar mentions 'The Formorian Wars' and a 'Formorian era'.
