T'odesser Prime is a world located in a strange part of the Milky Way galaxy. Nestled within the Morsmordre Nebula, the remnants of a massive supernova explosion billions of years ago, the world was hidden from the rest of the galaxy for millennia by the dust and expanding gasses. The planet was first identified in the initial survey of the Unknown Regions in 7 NE, but it wasn't until the Expansionist period under the reign of Empress Domina Walker that the Empire first made official contact with the alien world. A single T'odessi, whose origins were unknown at the time, did interact with the Empire sometime after 30 NE and go on to become the Sith Lord Darth Krull.
The Sith Lord Darth Malus is also a native of this planet.
