The Demon Territory is run as a feudalistic and a meritocratic society, where the strongest and most talented individuals can easily succeed instead basing on birthrights as seen in countries run by an aristocratic system. The Demon Lord, the leader of the demons holds the highest position available.
Due to constant strife between borders with the empire, there are numerous fortresses that are built dotted along the border. Past the fortresses are farmlands and agriculture fields. 
Currently, the territory is undergoing a rapid militarisation lead by the current Demon Lord, Ariel.
