Demons are hellish beings from the Ynfernael plane.


Immensely powerful, demons have been entering the mortal realm through rifts opened by Daewyl elves ever since the War of the Shadow Tear.[1] Flames surround the hulking body of a demon, and the strongest demons, referred to as Demon Lords, are able to overcome their opponents with sheer terror and dread.[2]

Demons called Ynfernael Hulks are a particularly fast and powerful breed. They aid their manipulative kin called Changelings, who are able to take the form of innocent civilians.[3] It is believed that Hellhounds also travel to the mortal realm from the Ynfernael.[4]
