The Obtrexta sector, a sector, existed in the Outer Rim Territories. It could be found in proximity to both the Raioballo sector and the Wastes. Among the planets residing within Obtrexta was Muunilinst.
The hyperspace route known as Myto's Arrow terminated, in part, within this sector.
Following the Battle of Endor, the Pentastar Alignment included this area as one of its constituent sectors.
