Darksoul Trilogy:

The man once known as Shadowstone has been reborn. He believes that the war against evil must be waged on an even higher level than achieved through the Hero's Guild and he trusts no one but himself to do that. Having vanquished and imprisoned Satan, Darksoul travels Existence seeking out the most powerful beings, those who claim to be gods, and destroys them. He believes that by doing so, he is doing the will of Jehovah, Almighty God. Those who survived the Curse, who were once Shadowstone's friends and brothers, see only that Satan has been replaced, for  Darksoul has no mercy, no compassion, no love.
