I've created a variant of the Canopus starmap, based on what is known to the Traders' Cooperative Network, a non-affiliated information source which will be available to the PCs.
Note the vast prevalence of Amber zones in the quadrant; most worlds outside the Restored Canopus Republic are marked as Amber zones due to problematic governments, unstable trade with the outside universe and other Wilds conditions. Using the Mongoose Traveller rules, this will mean that selling weapons will be quite profitable in the majority of the quadrant; also, there will be quite a hefty passenger flow from the Wilds into the safer worlds of the Restored Canopus Republic.
