The Ublik Passage was the location of Slag's fleet, located in Pirate Territory. This was where Ratchet and Clank fought and defeated Captain Slag. The Ublik Passage was previously used for connection between the Praxus and Verdigris Sectors. Allied Polaris used these routes to move supplies and troops across each sector during the Great War; however, the Cragmites later on detonated a nearby star. Radiation from the star remains made the passage too dangerous to try to cross. Then, it became occupied by Slag's fleet, natural since the Space Pirates were robots and thus unaffected by the radiation. In various locations on the fleet, whale-like animals can be seen flying around, just like the ones on Ardolis and Vapedia, which may mean they were introduced into that environment by the pirates.
