Omnicanism

Omnicanism is a religion referring to the post-Imperial Aurelianity. The office of Heliarch was first established in 469 AIC to serve as the Emperor's religious proxy in Urbs Archadia. During the Civil War that erupted soon after, the Heliarch became the single point uniting both sides, as people gathered to his religious authority rather than choosing between two emperors. As the High Priest of Archadia, the Heliarch was originally appointed by the Emperor, and during the Civil War he was elected by the Curia. As it became more and more apparent that the Heliarch is the de facto leader of Aurelianity, the College of Cardinals was established in 512 AIC, which elected the Heliarch. Omnicanism remained mostly true to the old Aurelian traditions. The divinity of House Garantius was never challenged, rather it became a claim that was not spoken about.

The administrative division of Omnicanism remained the same. People elected their bishops and from their list, the Heliarch appointed the archbishops. 17 of the archbishops who held their function for the longest time were given the position of a cardinal, who then elected a new Heliarch.

In 883 AIC, Emperor Nicodemus Garantius XLIV disbanded the office of Heliarch, officially ending the Omnican Church. In Archadia, Omnicanism has thus mostly been reduced to traditional Aurelianism.

The Order of Mount Sol claims to be the successor of the Omnican Church but no other state recognises this claim.
