Ublik Passage was once a bustling interstellar traffic zone that connected the Praxus Sector with the Verdigris Sector, with thousands of spaceships traveling the passage everyday. During the Great War, this route was used by Allied Polaris to ship supplies to races resisting the Cragmite's expansion. Its value was not lost on the Cragmites, who denoted a local neutron star in the passage, which made the entire sector completely irradiated from solar energy. With the entire passage being highly irradiated, the Ublik Passage was no longer safe passage way, which ended it's use as an interstellar passage way.
