The faithful and the chosen
Players are at liberty to choose the gods that their characters worship. Initiates gain their powers through their faith.
The gods are able to communicate with their followers, they can send messengers (who may or may not be believed) and they are capable of intruding into the dreams of their devotees. They can also grant blessings to their followers - these are significant magical powers or protections that the followers enjoy for a time as the gods will it.
A starting character may choose to be an initiate and select the god that they follow. It is also possible to be a devoted follower of the god you are initiated but this requires donations (tithes). A priest is a person who holds a position in an organised religion.
Fees: Devoted Followers pay tythes not guild fees and will usually not need to pay for training to improve their skills.
