The church of Trinity is split in to three main Sept’s. The Sept of War, The Sept of Balance and The Sept of Knowledge. The leaders of the Sept's are known as the High Cardinals, of each order, they serve the King Priest of the Theocracy.
There are a few ways to join. An individual can be part of a family tradition that joins, political reason, and the very rare few that get a calling.
Once someone joins the Sept’s they spend a few years as a Novice, after that they become an Acolyte (1 to 5 th lvl) of that house. Once someone becomes an Acolyte, they either receive an item or can use an item that means something to them. This item will be imbued with the power of their house. The item then becomes a lesser relic. To others it just looks like any common item, to those that use divine powers or can see divine power, it radiates divine magic if they use spells like detect magic etc.
If a Cleric loses the lesser relic, the Cleric will have to have a new one imbued or lose their powers as cleric.
