Fomorians is a term used to describe a brutal and powerful race of misshapen monsters. Also referred to as the "Elder Darks", they appear as colossi constructed from man's primal fears.
As creatures of winter and destruction, they can be seen as the progenitors of the Unseelie. In ancient times the Fomorians were the most potent champions of horrific dreams, perhaps even evil gods of a sort. Deformed beyond description, they were said to be inhumanly beautiful or inhumanly hideous. Woe to their subjects that cross their path - the noblity are tyrants who used to rule many of the Adhene.
Traditional enemies of the Tuatha de Danann and the Sidhe, they were banished into the depths of the Dreaming after they lost the War of Trees against their foes, and their followers were cast behind the Silver Path. In the present day, some still influence the Shadow Court.
In 20th Edition, the Thallain are their children, and their return in great numbers in the wake of the September 11th attacks is a herald of their awakening.
