Information on the Cameo
Sindragosa is an undead blue dragon in World of Warcraft: Wrath of the Lich King. She is first seen in the introductory cinematic, being resurrected by The Lich King and proceeding to rally an undead horde by flying over them and roaring, which seems to instill energy in them. Sindragosa is the matron of many other undead frost dragons serving the Scourge, and eventually appears as the penultimate boss of the campaign towards the end of the Icecrown Citadel raid. She also appeared on the login screen during the WotLK era.
