From the Books: "Trailward of our arm is the Jesc arm, the Centaur region. It’s a very populous region. The Galnet lists just over 500 occupied worlds controlled by 400 species.” Someone whistled. “A very diverse number of species, on mostly native worlds. It doesn’t have a high density of wealth though, so when it’s found, it’s pretty hotly contested. And as usual, as long as the locals play by the rules, the Union lets them deal with it.” - Cartwright's Cavaliers, p. 69-70.
