Quartu was the homeworld of Clank and was home to an enormous robot processing factory. It was a rocky desert like world with deep canyons and minimal vegetation. Clank returned with Ratchet to seek out Chairman Drek and instead found a giant mech professor and Clank's mother, the computer's core. She created Clank so that he could combat Drek's plans, and told the duo about Drek's plans to destroy Veldin.
It was also here that Ratchet and Clank encountered the Ultra-Mech Unlimiteds and gained the ability to make Clank bigger.
