One of the council members among the conspiracy group generally referred to as the Phantoms of the Purge. Once revered as a demonic god among a cult of warlocks, he lost all of his holdings in the mortal realms when a crusade fielded by the united holy pantheon sent out witch hunters to destroy demonic cults. He grew spiteful upon watching his followers be murdered and saught revenge. During the era of rising, Valadeus saw a unique opportunity and invested great effort into raising a champion among the chaotic age with a singular mission. Valadeus is the one who informed the mortals exactly how to kill their gods and orchestrated the invasion of the celestial realms from behind the scenes. Since he never entered into the middle planes, the purge never managed to reach him.

Valadeus is one of the most ancient demon lords though is not frightfully powerful. Having lost almost all of his holdings during the holy crusades and being forced to contend with terrifying demons in Finsor to try and rebuild his fortunes. He is a little spiteful that Asmoday outranks him despite being centuries younger. His membership within the phantoms is clearly to rebuild his lost kingdom once more.
