Triamis the Great became Emperor in 2478, beginning what most scholars consider the Ceneian Golden Age. In 2483 he conquered Nilnamesh, and then Cingulat the following year. In 2485, he defeated a great Zeümi host at Amarah, and would have invaded the Satyothi nation had not mutinies among his homesick troops prevented him. He spent the next decade consolidating his gains, and striving against the internecine religious violence between followers of the traditional Kiünnat sects and the growing numbers of Inrithi. It was in the course of negotiating settlements that he became friends with the then Shriah of the Thousand Temples, Ekyannus III, and in 2505 he himself converted to Inrithism, declaring it the official state religion of the Ceneian Empire. He spent the next ten years putting down religious rebellions, while at the same time invading and occupying both Cironj (2508) and Nron (2511). He then spent ten years campaigning across the eastern Three Seas against the successor nations of the old Shiradi Empire, first conquering Ainon (2518), then Cengemis (2519), and finally Annand (2525).
