The Breegus Nebula was located in the Polaris Galaxy. It led into the Breegus System at the edge of the galaxy. Ratchet received coordinates to the nebula from the computer of an Obsidian Eye on planet Merdegraw. He promptly flew through it in the Aphelion alongside Captain Qwark and entered the Breegus System in order to find his lost friend, Clank, who was held captive in the Great Clock by Dr. Nefarious.
