Corlax 4 served as a launching pad for Xer VIII's attack against the Livien League, from which he would strike against Amarin. It spent centuries changing hands between Jaminere and Desevro.
The planet had joined the Confederacy of Independent Systems, and it was immediately recognized by its raw materials that the Separatist holdings could use for their war machines. However, this got the attention of the Supreme Chancellor, who ordered Jedi Master Darrus Jeht to eliminate the Separatist facilities there. Jeht was unnerved by the unorthodox nature of this mission, as the order came directly from Chancellor Palpatine himself. He also questioned the need to have to exterminate the population of the planet. For the first time in his life, Darrus Jeht chose to disobey. The planet remained one of the CIS's key sources of war materiel throughout the Clone Wars.
