Sacrifice

The Holy War is over. The demons of Gologotha have been banished, yet the cost has been terribly high. The Creator, god of the Fyllid, has been defeated and the faith of the people has begun to wane. Petty squabbles among the five remaining gods has caused the land to split into five mystical territories - each at war with one another. Into this divided land steps a wizard, a man haunted by his past, whose choices will shape the future.

From the Sacrifice wikia: Sacrifice's campaign follows the story of a vagrant wizard known as Eldred. Five gods offer him a home, but Eldred must settle with only one. Early on in the campaign, the gods hear a prophecy that foretells their destruction by a traitor amongst them, a traitor that only a wanderer could defeat. As a result of this, their once harmless bickering transforms into all-out warfare, and Eldred must pick a side.
