Detheroc's Forces were a group of Undead under the control of the Dreadlord Detheroc. Many months after the Battle of Mount Hyjal, The Lich King began losing his power. With it, he also lost control over much of the Scourge. Detheroc and his brothers, Varimathras and Balnazzar took control over these undead and usurped control of Lordaeron from King Arthas Menethil. In addition to commanding undead, Detheroc used his telepathic powers to take command of the New Alliance, commanded by Grand Marshal Garithos. He established a well-fortified stronghold in the Western Plaguelands
