Warhammer Fantasy: Dogs of War

From the introduction:

Welcome jumper to Tilea, your newest home! Tilea is a nation of the Old World, lacking a central government. Sharing a common language and culture it is politically divided in twenty two city-states, seventy eight alliances and more politicking, assasinations, backroom dealing and skullduggery than you could ever have thought possible. An old joke about Tileans states that two strangers in a room together will spawn three factions and four civil wars in an hour.
