The Hand of Vengeance is a group of forsaken soldiers sent by Sylvanas Windrunner to put an end to the Lich King once and for all. Sylvanas was the former ranger general of Silvermoon. When the Scourge, led by the Lich King himself, invaded Quel'Thalas, Sylvanas fought valiantly but was ultimately felled. The Lich King then raised Sylvanas as a banshee, damning her soul for eternity. Upon breaking away from the Lich King, Sylvanas learned about what horrible fate awaited her in the afterlife. She gathered other undead and pledged to do battle against the Lich King. Realizing that she would be unable to exact her revenge alone, she pledged herself and her forsaken to the Horde.
