The Protectorate

Sandwiched between the Corporate Sector and the edge of the Galactic Empire, the Protectorate is a small frontier region whose continued existance relies on the treacherous hyperspace lanes of a supernova cluster. Travel between the black holes, dwarf stars and supernovae of this region is risky enough for small manoeuvrable starships; it would be a foolhardy Imperial or Corporate captain who attempted to navigate them in a warship.
A loose confederacy of corporations operating on the handful of habitable worlds are the closest thing to a government, although they are far from unified and their reach often exceeds their grasp. The dozens of frontier stations and outposts broadly pay lip service to the Protectorate, but it's a lawless space.
Attempting to keep the peace falls to the Protectorate Marshalls.
