Forsaken names keep a trace of the human they once were, with surnames of grave and decay. Paladins carry names with a ring of oath and light. Undead Paladin is one of the new combinations in WoW Forever, so expect a lot of players to try it at launch.
Every character in WoW Forever has a first and a last name, and only the full combination has to be unique in your region. So a popular first name is still usable with a less common surname.
Example names: Jarian Maggotfield, Baroith Graveborn, Vexeorn Shroudwell, Ashvaeth Ravenwither, Bar Mourn, Melaella Shroudhold, Corias Mournshade, Cyreaine Gravesend.
