Inrithism is the faith founded upon the revelations of Inri Sejenus, the Latter Prophet, which synthesizes elements of both monotheism and polytheism. The central tenents of Inrithism deal with the immanence of the God in historical events, the unity of the individual deities of the Cults as Aspects of the God, and the role of the Thousand Temples as the very expression of the God in the world.
Following the alleged ascension of Inri Sejenus, Inrithism slowly established itself throughout the Ceneian Empire as an organized hierarchy independent of the state—what came to be called the Thousand Temples. Initially, the existing traditionalist Kiünnat sects simply dismissed the new religion, but as it continued to grow, a number of attempts were made to circumscribe its powers and prevent its further spread, none of them particularly effective. Escalating tensions eventually culminated in the Zealot Wars (c. 2390-2478), which, although technically a civil war, saw battles fought far outside the boundaries of what then constituted the Ceneian Empire.
In 2469, Sumna capitulated to Shrial forces, but hostilities continued until Triamis the Great was anointed Emperor in 2478. Though himself Inrithi (converted by Ekyannus III), and despite enacting the constitution governing the division of powers between the Imperium and the Thousand Temples, he refrained from declaring Inrithism the official state religion until 2505. From that point the ascendancy of the Thousand Temples was assured, and over the ensuing centuries the remaining Kiünnat “heresies” of the Three Seas would either wither away or be forcibly stamped out.
