Captain, based on the results of Schlock's hypnosis, and a search through hypernet logs of shipping and law enforcement, I've found his home system.
Listed as 'Ghanj-Rho,' it's one of several hundred ancient stars in the eastern spiral arm.
The system is a haven to smugglers, privateers, and guns for hire. The only planet of mention is an ecological disaster with no extant civilization to speak of, and a surface littered with abandoned cities.
Mmmm. Stop that. You make it sound so enticing.
