Soulbringer

Thousands of years ago six demon kings, known as the Revenants, ruled the world with an iron fist and bloody swords. Donning the bodies of mortal vassals, they could live in the realms of man forever. The great hero and warlock Harbinger was the only one who could stand up to their power. One by one he hunted the Revenants, taking their spirits and casting them into the Well of Souls.
