Byzantine emperor, Basileus and autocrator Demetrius I of the Lascaris dynasty, nicknamed "Ursus". Tough, iron-willed, uncompromising, sullen, rude, short-tempered and stubborn, modest in life and completely alien to luxury. He hates all the enemies of Byzantium, especially the Germans and Turks. He never calls Byzantium "Byzantium", calling it "Romeion" or "Roman state" or "Roman Empire", he gets angry if someone calls Byzantium otherwise.
