Eriadu

Eriadu was the primary world in the Seswenna sector, and one of the Outer Rim's most active trade centers. It sat on the intersection of several hyperspace routes, including the Rimma Trade Route, the Hydian Way, the Lipsec Run, and the Yankirk Route.

The planet had originally been on the Eriadu Bypass until the Hydian Way was remapped to run through Eriadu rather than Seswenna. It was an important launch point for ships headed to the Moddell sector, such as the colony ship "Free Enterprise" in 130 BBY.

 The Shadow Empire 

Rising from the ashes, 1,000 years after the Galactic Triumvirate, Eriadu served the Shadow Empire as a militant base for the Shadow Army and a spaceport. The planet was also used as a shipyard to repair starships, starfighters, and much more aligned with the Shadow Empire. With the militant base for the Shadow Army, there was also a security base and launch port. Also, throughout history, the planet was also a place for the Grand Moff Tarkin's Memorial Center.
