Varimathras is likely second in command of The Forsaken. He is a Dreadlord, a race of demons from The Twisting Nether used as commanders for the invasions of the Burning Legion. With the fall of the Legion at the Battle of Mt. Hyjal, he and several of his brothers were abandoned in the Plaguelands at the Ruins of Lordaeron. They had no news of the defeat of the Legion, and continued to rule over the undead stationed there while waiting for further instructions from Archimonde the Defiler. Their fortifications were assaulted during the Undead Civil War by the forces of the Forsaken and their leader Sylvanas Windrunner, and Varimathras was captured by the Dark Lady. Out of cowardice, he swore fealty to her in order to preserve his own life and assisted her in the destruction of the Dreadlords Balnazzar and Detheroc. He personally attacked and was forced to have killed his brother Balnazzar, leader of the Plaguelands’ Legion forces. Since then he has assisted Sylvanas in her rise to power as ruler of the Forsaken, and aids with her from the Undercity. He runs the day to day affairs of the undead faction, monitoring the progress of the Forsaken’s war against the Scourge and the Scarlet Crusade. His position is highly special as he is the only former member of the Burning legion who openly became one of the rulers of the Azeroth faction (Horde). Although he is a powerful leader of the Forsaken, he does not give honor when killed.

Seeing that the battle was ending and that his comrades were far outnumbered, Arcanister fled with a handful of survivors to Dalaran in order to warn the Kirin Tor. When Arthas and Kel’Thuzad made their inevitable journey to Dalaran, the Mages were more than ready for them.

However, this spell had to be maintained by 3 Archmages, and Arcanister was one of them. Arcanister guarded the Gates of Dalaran and maintained the shield and held off the Scourge for a brief period. However, the Undead used devious tactics to combat the Wizards and humans of Dalaran and Arthas was eventually able to kill the Archmage.
