Once the Ranger-General of Silvermoon, Sylvanas Windrunner was murdered by the death knight, Arthas, and brought back as a creature of undeath; as such, she hates Arthas with a passion. After regaining her free will, she rebelled against the Lich King and the Scourge and became the founder of the Forsaken faction of undead, who are allied with the Horde. She has styled herself the Dark Lady, Queen of the Forsaken, an expansion of her original title, "the Banshee Queen".
Sylvanas Windrunner is a minion for use by any class. For the cost of 6 , she allows the friendly hero to gain control of a random enemy minion when she dies. She also comes with moderate attack and health.
