This mod is dead. I'll release what I have just for the hell of it, but don't expect anything better,
During the period known as the Great Devastation, hundreds of demons were awoken by the Cult and sent on a rampage through the Known Lands. They crushed kingdom after kingdom and carved a bloody scar right up to the Silver Gates. They were chiefly Pit Vipers and Zbrondhak, but many Cultists of the Man Sect offered their bodies up to be inhabited by lesser demons. Those that did were mobilized into a force of Black Vipers, possessed men of the Cult.
