Liturgy of Hours

The Order of Priests can bend reality by harnessing the metaphysical powers of belief latent within sentient beings. To accomplish greater and greater changes, the Priests have discovered that Rituals with participants conducted in regular cycles are best. The more elaborate and sophisticated, and the more indoctrinating, the better. 
Priests will often task their followers with regular Rituals, both personal and communal, to keep up the Priests metaphysical abilities. Most Priests won't learn to do this until they are well into the ranks of the Order, but the oldest of them often lead religious organizations of great size. What exactly they can do, and to what extent they can affect reality, is unknown even to the younger Priests.
