At the age of 14, everybody gets a so-called “prophecy” from the priests. The prophecy tells you of your future and whether you are doomed to hell or destined to an afterlife of eternal bliss. By modern standards, this is totally unfair, but to the people in this play, to follow your destiny or to struggle against it is central.
Mechanically, this is a cultural trait granting you a fourth belief (see the World Burning section).
Priests are able to spritually communicate their prophesies to other priests. Usually any priest can know your prophecy by making a successful Faith check, obstacle equal to 10 - the target character’s reputations and affiliations.
