Belsus
this was one of the many moons of the planet Gentes. During the Clone Wars, the Separatist forces under the command of General Grievous maintained control of Gentes and the Anoat System from a base on Belsus. Although Belsus was an arid world capable of sustaining life, Grievous ordered his droid armies to eliminate most of the population of the moon, in order to maintain the secrecy of his base. The reason for the secrecy surrounded Grievous' plans to meld the Force-sensitivity of captured Jedi Padawans to specialized Geonosian technologies, in an effort to create a Force-sensitive version of himself.
