The Imperium is a loose collective of democratic city states that dominates the western half of the world of T.O.E. Brought together hundreds of years before the events of Dragomir's Diary, the Imperium is much less expansionist and militaristic than its name suggests.
The Imperium is nominally controlled by a central senate of representatives. In reality, however, most cities and towns have control over their own affairs, and are responsible for their own protection. Kingdoms and queendoms are virtually unknown in the Imperium.
Because it stretches across a massive portion of the world, the Imperium consists of dozens of different races, generally living in peaceful co-existence. These races include humans, orcs and snake people.
