Estosh, a male Vagaari, held the position of Supreme Commander within the Vagaari Empire and was instrumental in seizing a Dreadnaught from the wreckage of Outbound Flight. His birth occurred sometime after 27 BBY. He adopted a disguise as a Geroon and headed the Geroon Remnant, which was a false front designed to mimic the real Geroon government. Leveraging this deception, he infiltrated the expedition to Outbound Flight, but his death came as he attempted to pilfer a dreadnaught from the Outbound Flight Colony, employing a poison originally crafted to eliminate Jedi Masters Luke and Mara Jade Skywalker.
