Baratus

The Killer of Kings, Baratus is the Plane of Negative Energy made physical. He often takes the form of a regal Nightwalker, the form of his firstborn, Zedek. While a part of the Tribunal, Baratus has always found that the undead, his kindred, are overlooked or outright exterminated. For eons he volleyed for equal treatment of his children, but the universe deemed his ilk "Unnatural". As a result, Baratus has spent the last six thousand years trying to blot out the suns of the material plane.
