Corlax 4, often shortened to Corlax, was a planet situated in the Allied Tion sector of the Outer Rim Territories. This industrial world, not particularly notable, was home to nearly 300 million Humans during the Clone Wars, who were primarily employed as laborers.
Corlax 4 was the location from which Xer VIII initiated his offensive against the Livien League, with the intent of then attacking Amarin. Control of the planet shifted back and forth between Jaminere and Desevro over many centuries.
The Confederacy of Independent Systems gained this planet as a member, and the Separatists quickly realized the value of its raw materials for their war effort. This, in turn, drew the attention of the Supreme Chancellor, who tasked Jedi Master Darrus Jeht with destroying the Separatist installations present there. The unusual nature of this assignment troubled Jeht, as the order originated directly from Chancellor Palpatine. He also questioned the necessity of wiping out the planet's inhabitants. In an unprecedented act, Darrus Jeht defied this order. Throughout the Clone Wars, the planet continued to be a vital source of war supplies for the CIS.
