The term "beastman" refers to any intelligent, humanoid creature that owes its origin to Eldritch sorcery. The two most commonly encountered types of beastmen are orcs, created from boars, and gnolls, created from hyenas, although other types have been reported in remote regions of the world. As the products of demonic sorcery, all beastmen are touched with Chaos and, as such, are implacable foes of both Men and civilization.
Owing to their unnatural origins, beastmen are spawned in alchemical vats located in underground Eldritch strongholds. The discovery and destruction of these strongholds has, since Thulian times, been of paramount importance for beastmen spread like an infection across the world, their numbers continually replenished through arcane science. The recent breaking of the seals on Dwimmermount seems to have contributed to a rise in the number of beastmen, suggesting that the mountain-fortress contains or controls -- or both -- additional spawning vats.
