Darg-3 was a point in the vastness of space, specifically a hyperspace jump location designated by a navigation buoy. The Imperial heavy cruiser, a Dreadnaught-class prison ship named Dargon, was on a course to arrive at this jump point. However, before it could arrive, Rebel forces attacked in an attempt to seize control of the ship by disabling it. It is thought that the Dargon ultimately made it to Darg-3, but it remains unknown if the Empire or the Rebellion was in command when it did.
