Jard Dooku was a Human Jedi Master who lived during the time of the Invasion of Utapau. He had once been the master of Xanatos, who later tried to assassinate Dooku on Bandomeer. The assassination was unsuccessful as Obi-Wan Kenobi, a rejected Jedi Padawan assigned to the Jedi AgriCorps mine on the planet, was able to stop it beforehand. This prompted Dooku to take Kenobi as his apprentice, and they trained together for many years under strained circumstances as their views conflicted with one another. After the Stark Hyperspace War between the Galactic Republic and the Stark Commercial Combine, Kenobi became a Jedi Knight, but he and Dooku still worked together.
