Estosh was the Vagaari Supreme Commander who played an important role in the capture of one of the six original Dreadnaughts from the ruins of Outbound Flight. He was born sometime after 27 BBY. After disguising himself as a Geroon and slipping among the expedition to Outbound Flight, he later died trying to steal a dreadnaught from the Outbound Flight project, after using a toxin intended to kill Jedi Masters Luke and Mara Jade Skywalker.
