Attached are different versions of the maps I'm using for my Sentinel Gate Affair campaign. After all, space can have maps too, right? My thinking is that the maps don't depict all the stars in an area, just the ones that have particularly interesting known worlds. (So there's nearly infinite possibility of stuff in the spaces between, and particularly in the cloudy areas, which are supposed to be particularly perilous to navigate. There be dragons.) That said, if you want fuel or supplies, the maps will get you to the space truck stops handily enough.
All of this is in the galactic north precisely because we can't see that part, so I get to just make it up and nobody can tell me I'm wrong.
The first is the Imperial chart of the Tartarus Rim.

The Holy Terran Empire has better intelligence on the Memphian Sector, so they also have maps of typical warp currents to aid in navigation. (Warp currents will tend to cause deviations in warp transits in their direction.) Such currents exist in the Tartarus Rim as well, but Terra has no intel on that. The two sides are on slightly more even footing in that regard int he Memphian Sector.

I've also written up some short, encyclopedia style entries on the various systems depicted detailing what's in them, why they're important, and so forth. (But mostly, it's so the players know where they can buy snacks.)
