Ironbound Wraithcharger - one of the reward mounts for competing in timewalking dungeons available only during "Wrath of the Lich King" timewalking weekends. Timewalking is a dungeon difficulty added in patch 6.2.0 of Warlords of Draenor, allowing players to queue up for a randomly selected old-school "Burning Crusade", "Wrath of the Lich King" and "Cataclysm" 5-ppl dungeon. Timewalking difficulty scales down the character's power and gear relative to the dungeon.
