Cerullean Sector

The Cerullean Sector is the sector of the Polaris Galaxy where Ratchet and Clank first crash land onto Cobalia and meet Talwyn, Cronk, and Zephr. The Cerullean Sector's known planets and locations include:


 * Cobalia
 * Kortog
 * Fastoon
 * Voron Asteroid Belt
 * Mukow
 * Nundac Asteroid Ring
 * Ardolis

The duo leave the Cerullean Sector when they depart from Ardolis. The Cerullean Sector is revisited later in the game when Ratchet and Clank go back to Mukow, and when they go back to Fastoon and the end of the game.
