Are you referring to the Prophecy Map? And I reckon there's very little (published) info on factions outside of Confed, Kilrathi, and Border Worlds. I know a little about the Firekka, Steltek, Kilrathi Feudal Planets, double-helix, and Pilgrims, but virtually nothing about the Hari, Landreich, Yan, and surely half a dozen other factions. Not to mentioned the (somewhat separated) universe of Privateer 2, since it's the only WC game I haven't played.
