The Orus Sector was situated within the Inner Rim Territories. Among the planets located in Orus were Kimanan, Mantessa, Chazwa, Joiol, Poderis, and also Hijarna.
During the period of the Thrawn campaign, the New Republic mistakenly thought that the movement of Grand Admiral Thrawn's clone forces occurred through this region. Luke Skywalker then employed smugglers, who would later form the Smugglers' Alliance, to explore the sector. Ultimately, they determined that Thrawn had deceived the New Republic.
Star Wars: Rebellion erroneously includes Tatooine, Ryloth, Daltarra, and Bakura as being part of the Orus Sector. The planet Tatooine is actually located in the Arkanis sector, while Ryloth is found within the Gaulus sector, and Bakura lies on the Shiritoku Spur inside the Bakura sector. Moreover, Rebellion incorrectly identifies the sector as being in the Outer Rim.
