Tieran was a male Ilarian who became Autarch of Ilari in the late 22nd century. While initially being a uniting force for the Ilarians, Tieran soon became manipulative, power hungry, and extremely ruthless. Eventually, his terrible reign was finished when he was overthrown. Eventually, Tieran's consciousness was removed from Kes when an away team from Voyager were able to use a synaptic stimulator. Tieran was then killed when he attempted to transfer his consciousness to one of his aides. (VOY episode: "Warlord")
