Morseer was a world located in the Quelii sector of the Outer Rim Territories with a methane-rich atmosphere. Morseer was colonized by the methane-breathing Morseerians, a secretive species who had kept secret the actual location of their homeworld to the rest of the galaxy during thousands years. Hence, the Morseerians were named after their colony of Morseer by the Drackmarians after they conquered the world. After the conquest, the Morseerians became a client species of the Drackmarians, another methane-breathing species. Sometimes prior to the Battle of Endor, the Galactic Empire defeated the Drackmarians and claimed Morseer.
