The Deoran Empire (Deoran: Imperium Deoracum, Classical Cestrosian: Βασιλεία Δευραίων) was the imperial phase of Deoran civilization, characterized by the rule of a series of absolute monarchs styled as emperors. Deoran civilization reached its greatest territorial extent during this period; conversely, it suffered internal crises and fragmentation to an unprecedented degree, which along with a series of barbarian invasions brought the end of Deora as a unified civilization.
The Deoran Empire is commonly regarded as solidifying the base of Patyrian civilization today, in part through its propagation of Mogevianism during its later years. The Deoran Empire's former territories comprise numerous nations with continued global relevance, particularly Apelia, Granzery and Tierada.
