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 Zephyr. The Cerullean Sector's known planets and locations include:


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

The duo crash land on Cobalia and meet The Smuggler, who gives them a flight to Kortog, only to eject them through the cargo hold. On Kortog, in the Hall of Knowledge, Ratchet and Clank get the coordinates to Fastoon. On Fastoon, they find an old Lombax ship named Aphelion. She becomes their ship for the rest of the game. Qwark sends them an invite to Mukow for the Imperial Fight Festival, where they win the Heli-Pod. On Nundac Asteroid Ring, they meet Talwyn, Cronk, and Zephyr, who help them find the Lombax Secret. On Ardolis, Ratchet and Clank steal an artifact that belonged to Talwyn's father back from the Space Pirates. Later, at the end of the game, on Fastoon, Ratchet, Clank, Talwyn, Cronk, and Zephyr fight through Tachyon's forces and learn the true fate of the lombaxes. During the fight with Tachyon, the Dimensionator creates a portal that places Ratchet, Clank, and Tachyon on an Asteroid in another dimension. Ratchet and Clank defeat Tachyon, as he goes flying into a black hole, and escape back to Polaris.
