Ok, I'm having a little trouble trying to figure out just how many stars there should by in 20 cubic light-year area, and please don't say as many as the story calls for. Also how many of them should have planets? Etc... What I have other than star systems is a Mid-sized nebula, a rogue planet, and possibly a small singularity type object. As far as species in the area go, I have three native (one pre warp, but...) and two (or more) transplanted.
The sector (called "Hadnido") is located on the anti-Federation side of Cardassian space, just for GP.
