In 3,996 BBYAleema Keto used Sith magic along with the ancient ship Corsair to destroy the nebula known at the time as the Cron Cluster, creating the Cron Drift. During the Cron Supernova, all planetary bodies in the vicinity were smashed, with the debris becoming scattered throughout the region. The greatest concentration formed the famed asteroid field itself, and it held a reputation as a hiding place for all sorts of activity such as pirating, looting, and smuggling of illicit materials. The worlds of Dalos IV, Belderone, Kulthis, Ossus, and Nespis VIII were the closest to the Drift. The Cronese Mandate and the Tion Cluster were located near the Cron Drift.
Sometime before the Invasion of Naboo, the UmbaranSly Moore was imprisoned by Darth Maul in a tomb somewhere within the Cron Drift after he captured her. She was haunted mentally and spiritually by ancient Sith before Darth Sidious came and rescued her.
An Imperial force consisting of four transports, escorted by Assault Gunboats attacked the rendezvous but were defeated by X-wings flown by Keyan Farlander and Puck Naeco, allowing the transfer to take place. The satellites proved essential in discovering the Death Star I project.
