Due to my overwhelming love for all things Battlefleet Gothic, I decided to run my RT game in one of the sub-sectors of the Gothic Sector and eventually decided on the Cyclops Cluster. As a complete and total coincidence, the Cyclops Cluster happens to be the home for Mezoa, familiar to most of you as being the home for half the energy weapons in the game.
As it's doubtful FFG will publish a book detailing worlds for my game specifically, I've built a cheat sheet for the sub-sector for my players, alon with most of the major players in the region and their relative Influence ratings (Profit Factor equivalent, for anyone who hasn't read DH: Ascension). As my players have been having a lot of fun with it, I figured some of you lot might also appreciate it - or at least rip it off for your own games, which is good enough for me.
Use this as you will. I'm currently going through and doing details for the sub-sector Rogue Trader dynasties and other mercantile concerns. If people find use in what's here so far, I'm more than happy to post that when it's done.
