Founded 1204 years ago by Emperor Yulla I. the Empire is a monarchy in which the Emperor has supreme rule over everything. To help his rule the Emperor appoints Lords, mostly from branch families of the Imperial family which rule over provinces with the help of their vassals. The citizens of the Empire fit into one of the following categories (by social standing and power):
Imperial Family (less then 1% of population),
Lords and Court Mages with their families (1-2% of population),
Knights and Low-rank Mages with their families (10-11% of population),
Free Citizens (20-22% of population),
Serfs (45-50% of population)
and Slaves (15-24% of population).
All citizens excluding the Imperial Family and the Slaves (which don't posses money at all) pay three taxes -
Imperial (5-25% of all yearly income, depending on the needs of the Empire),
Local (5-25% of all monthly income, deepening on the needs of the province)
and Property (7% monthly on all property that one possesses - land, furniture, slaves, art works and so on).
Taxes can be paid in money, work or nature.
Guilds
Guilds are backed by the Empire and ensure monopoly over specific jobs or commodities it their area or even the whole Empire.
The Army and City Guards
The Imperial Army is recruited from all social classes except Slaves. All of it's members undergo harsh physical training, officers and regular soldiers alike, before joining the active forces.
Most cities have paid city guards which are hired by the local government to keep peace and fight guards. Only the Imperial City of Irian has an elite battalion of the Imperial Army protecting it and the Emperor.
The greatest threat to the Empire are the Northern Tribes which inhabit the cold part of the world and live mostly a nomadic life. Aperiodically great warlords arise amongst them and launch attacks in the Empire, which although causing great chaos and destruction as well as loss of lives and soldiers usually don't achieve anything but increasing the number of slaves that the Empire has. But this attacks stretch the Empire's military, increasing the threat of an attack from one of the smaller countries which borer the Empire, especially from Abrussi or Itakka which both have a long history of hate with the Empire and strong armies.
The current Emperor is Harise III. which took over the throne in IY (Imperial Year) 1193.
The de facto leader of the Imperial Army is General Tarak Lunner.
