The Seltaya Major system, a star system, resided within the Mieru'kar sector of the Outer Rim Territories and was the location of the planet known as Seltaya Major.
The placement of the system was inconsistent across sources; Twin Stars of Kira situated it in the Expansion Region, but Wanted by Cracken referenced a planet named Seltaya and placed it within the Mieru'kar sector of the Outer Rim. Both sources depicted Seltaya as an icy world serving as a pirate base. This discrepancy was resolved by The Essential Atlas, which retconned the Seltaya from Wanted by Cracken as Seltaya Major within the Seltaya Major system, and the Seltaya from Twin Stars of Kira as Seltaya Minor (or Ropagi III) within the Ropagi system.
