The Dorin Run was a smuggler route, leading to the planet Dorin, discovered in the days of Darth Krayt's Galactic Empire.
The planet was naturally situated between two black holes, making access to the planet limited. Conversely, due to the natural atmospheric conditions of the world, space travel for the natives was highly dangerous without the use of a breathing apparatus. Earlier, in the reign of the new Empire, the Imperial Navy blocked all the available routes to the Kel Dor world. The Sith then ordered that the best and brightest of the Kel Dor offer their service to the Empire, lest their people suffer. Subsequently, many Kel Dor entered the Imperial service, and still the blockade remained in place. An alternate route, the Dorin Run, was eventually discovered by smugglers, though it lay so close to the black holes that all but the most reckless considered it too dangerous to use.
