Shadows in the Void
Farside is a moon in the otherwise uninteresting system of Bartow. Farside is rumored to house a large highly secure vault run by The Shadow Ring. No questions asked, security guaranteed. Many people have tried to find the vault, those that come back report finding nothing.
Because the Bartow system has no planets worth mining or living on there is no real CPG or RPC presence there. This is the reason, the rumors claim, that the secret vault is located here.
