Dark Heresy- Burn the Heretic
Quaddis is a plaything of the rich and powerful, each of them own their own fiefs, areas that are completely under their control. There is no law but the law of the lord in the fiefs and even in the capital city of Xicarph there is very little in the way of a centralized police force.
