Belt Fortress

There are 4 Belt Fortresses that orbit in the Asteroid Belt, each is built through the middle of one of the belts larger asteroids, Ceres, Pallas, Vesta, Hygiea, and spin within the hole to create their own gravity.

As well as military fastnesses with hangers for the largets number of warships in the Empire they are also trade hubs, a way station for ships and workers, but not much cargo as mined materials are usually transited directly from site to their destination.

the four fortresses are called:


 * Qinglong Fortress (at Ceres)


 * Baihu Fortress (at  Pallas )


 * Zhuque Fortress (at  Vesta )


 * Xuanwu Fortress (at  Hygiea )
