The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed. For more information, see the new capitalization policy.
The Corvus Sector was a sector of the Breegus System in the PolarisGalaxy. The Corvus Nebula was its entrance. There was a space depot in this sector, as well as 4 different moons. It had the least amount of celestial objects in the Breegus System, but it was also the last sector that Ratchet visited. Qwark claimed (during Full Frontal Assault) that a group of Mutant Space Ninjas had been spotted in this sector.
