Seswenna was a planet located in the Seswenna system of the Outer Rim Territories. During the High Republic Era, the planet was a stronghold of the Galactic Republic. When the Nihil marauders expanded the Stormwall that surrounded their Occlusion Zone territory, Seswenna suddenly fell within Nihil space.
Admiral Conan Antonio Motti, a human male who was a member of the Imperial Military's Joint Chiefs and head of naval operations aboard the first Death Star, was from Seswenna.
