Hisseen, located within the Mid Rim Territories, served as the planetary origin for the Hisseenians. This planet became a target for the Confederacy of Independent Systems during the Clone Wars. In 22 BBY, the Separatists launched an attempt to capture Hisseen, prompting the Galactic Republic to dispatch Jedi Generals Obi-Wan Kenobi, Plo Koon, and Anakin Skywalker to defend both the world and its people.
