Marixx was a human female Warlock. During the Burning Legion's third invasion of Azeroth, Marixx interrupted a ritual of Gul'dan and stole the Scepter of Sargeras. However, she was later captured by demons and brought to the Twisting Nether, where Sargeras forced her to serve the Legion. During the siege of the Nighthold, the Legion forcefully took control of Marixx's mind after she attempted to turn against them. She was later freed from serving the Legion following Gul'dan's defeat.
