PC Invasion: Creative Assembly have announced all four legendary lords for Total War: Warhammer 2’s Curse of the Vampire Coast DLC. One of them is completely original: Cylostra Direfin — a Bretonnian opera singer who was lost at sea only to reemerge later leading ghostly Syreen and Bretonnian Knights trapped in eternal damnation.
