The demon hunters. Vengeful harbingers of righteous doom who bring swift judgment and death to the hellish creatures daring enough to trespass on the mortal lands of Sanctuary. Skilled archers, assassins, and trackers, demon hunters are perfectly honed instruments set to scour demons from the world. The fact that every last one of them has a deep and personal motivation to do so only sharpens their deadly purpose.
