Lone Wolf visits Mogaruith in The Plague Lords of Ruel. The Cener Druids, under Archdruid Cadak's leadership, had been developing a virus which they intended to use to kill all their foes. They also bred hordes of Vazhag in Mogaruith's spawning pits. The Elder Magi had discovered this plan and organized an invasion of Ruel, but were decisively defeated. When Rimoah approached Lone Wolf for help, Lone Wolf ventured into Mogaruith alone and destroyed the virus as well as the spawning pits.
