Kerkoidia was located within a star system in the Kira sector of the Expansion Region of the galaxy. It had a temperate climate, standard gravity, and three moons. Most of the planet was covered in savannahs, where tall grass grew to heights of nearly two meters. These savannahs, as well as thick swamps, which covered nearly 30% of the planet, and jungles, were inhabited by vicious predators.
During the Clone Wars, the planet was located within Separatist space, despite still being recognized as a member of the Galactic Republic. The planet was conquered by Admiral Kreuge of the Republic shortly after the Battle of Christophsis. The planet was also the home planet of the Confederate General Whorm Loathsom.
