Warhammer: Age of Sigmar - Battleforce - Soulblight Gravelords: Lances of the Crimson Keep

Prince Vhordrai once had the temerity to try to overthrow the tyrant Nagash, and his failure cost him his freedom. Now he lives shackled to the supernatural Crimson Keep, a phantasmal citadel that appears in ruins of strongholds around the Mortal Realms. When its gates open, he rides forth on the Revenant Draconith Shordemaire, leading  his Blood Knights into battle, cursed to fade to nothing if he doesn’t ride back to the Crimson Keep before it disappears again. 

The Lances of the Crimson Keep contains Prince Vhordrai on his monstrous steed, who commands 10 Blood Knights, savage crimson-armoured vampire cavaliers who ride down their foes with brutal efficiency. There are no vampires without bats, and three Fell Bats follow these imperious bloodsuckers around, feasting on foes shattered by the Blood Knights’ charges.
