In 702 BBY, the Grissmath Dynasty formed a penal colony on Nam Chorios. The Grissmaths let loose drochs on the planet in an attempt to kill the prisoners, but it was unsuccessful. Eventually, the descendants of the prisoners became a tough, independent group of settlers called the 'Oldtimers'. Centuries later, a failed Hutt Jedi, Beldorian, came to Nam Chorios, and set himself up as a dictator. The response to his self-appointed dictatorship is unknown. In 19 BBY Republic Senator Seti Ashgad was exiled to Nam Chorios by Supreme Chancellor Palpatine, and he filled the power void left by Beldorian's failure to keep the populace in check.
