Tau-23 (Border Worlds) is between Bretonia and Kusari. Bretonia Mining and Metals estabilished a base to exploit the resources in the system, but the Independent Miners Guild also estabilished their own base. This system is claimed by the Outcasts, who use it as entrance for their drugs smuggling into Kusari. The strong criminal presence and the continuous radiation make this system dangerous for the miners who work here and for the occasional travellers, unless they get on well with the Outcasts.
