Sellasas, a planet, housed both Imperial and non-military inhabitants shortly after the Battle of Yavin.
In the initial stages of the Galactic Civil War, Governor Jedselk oversaw the planet. Following the Battle of Yavin, a Rebel strike force placed Sellasas and its resident Imperial army garrison under siege. Among those involved in the conflict were Tyionsis Cex and Amara Jedselk, the governor's offspring.
