Almost everyone on Telandron worships one or more of the Pantheon of Thirteen. For the majority of them, mere prayer is not enough, and some require some sort of sign from their patron deity. This is where Clerics come in.
Clerics are members of a religion, devoted to converting and serving. They run temples in major cities and towns, where ordinary citizens go, worship their deity, and pray for guidance.
Most citizens visit their respective temple(s) once every few days, but obviously if you are a Cleric you are supposed to go more often.
Out in the wilderness things are very different from the crowded temples of the cities. There a consecrated rock is considered worthy of being a worshipping spot. Very few villages will have temples, most having a simple shrine carved from marble and a village priest.
Elves commonly build shrines of white stone and marble to their respective deities. Dwarves often carve into rock faces to produce worshipping places. Centaurs on the other hand, are different. They carry their prayers by word of mouth, which are chanted to H'Graash (also known as Kaarn).
It should be noted that although visiting temples can bring spiritual guidance and inner peace, many Clerics expect some payment (for holy reasons only, of course, such as repairing the temple roof).
