The most common and popular faith is The Art of The Divine Angels which holds the belief of the purity of the soul and the heart. They believe that if you hold a pure heart you will go into the sky instead of going down the underground where it believed that it harsh and corrupt souls are forced to work until they are forgiven and this depends on how bad their sins were. 

The Art of The Divine Angels churches often has a pair of Guardians master of Light Magic and the Sword alongside being vigilance and always on alert. Guardians are selected at a very young age around 8-10 or younger (or older it depends) either from orphans, nobles, or etc. First, they check on their history to see if they commit any sins. Second, they were examined by the Nuns to see if they have a bad heart or soul. Third, the child is then trained by a fellow Guardian which lends from the Temple alongside another child where they become close friends and partners they are often the same age. This often takes a couple of years and if one of them gets punished the other gets punished. Training starts very early before even the sun rose they training until the sun goes completely down then both of the children will pray alongside their assigned Guardian until midnight where they finally go the sleep. Both of them must take a light vow every day never to partake in pressures, gambling, greed, lust, and corruption. When they become nearly adults (which is around 17)they both take in a full vow that promises them to never break an oath nor vow. If any of the oaths/vows were broken they will be buried alive left to die. Being a Guardian is very honourable and will grant your parents with massive wealth and statues alongside all of your other relatives but after they take the full vow they become Guardians until they die. Where their bodies will be buried in the main temple. 

They can be released from their vow/oath but it very dishonourable and will permanently affect you, your parents and your relatives.
