By and large, each dwarven city is a nation-state to itself. There is no level of government or law above the city state. However, all dwarves rely on each other economically, and the various cities ally for mutual defense. The cities all contribute to a common standing army, which in times of peace is kept relatively small and is commanded by the most senior officer in service.
All the cities are ruled by their craft guilds, with a single, powerful guild ruling each city. The most powerful master of that guild acts as the de facto monarch. While most cities are ruled by mountain dwarf guilds, a few are dominated by a hill dwarf specialty. Mountain dwarves still hold enormous political and economic power, even in these hill dwarf strongholds.
