The Empire of Woman is rife with chaotic internal unrest.
As well as the ever present threat of Dissidents the various arms of the Empress government do not get on at all and often come to blows on a small scale in various secluded corners that go unwatched by the Quizzers (who often start these conflicts anyway!)
Warbands in Whores Blade 20,000 choose their Allegiance at the start of play.
Each Allegiance subtly changes the Warrior Creation process and applies unique tactical strengths and weaknesses to the Warriors in play making their battle plans highly varied.
The Core Rulebook covers the main human factions in play.
At some point I will get round to writing Alien Nations which shall detail the various Alien species and their politics (assuming they arent integrated into the Empires.)
