Religion
Religion is the intricate manifestation of reverence and ceremonial practices directed toward either a single deity or a pantheon of gods, where individuals and communities commit themselves to fulfilling the desires and mandates of these supreme entities. Because the gods are real, religion in the game setting cannot be a matter of either faith or belief. Instead, "religion" hinges on the readiness of independent, conscious persons to sacrifice their needs, wants, and indeed their very lives, for the sake of more powerful beings. Every thinking being is faced with this stark choice: dedication to a religious cause or self-determination.
Religion in the game world serves as a foundation for culture, social values and the moral compass of different societies and races. The game classes cleric and paladin are greatly influenced by the presence and respect for religion, as these characters must choose a religion for themselves. In their case, it can be stated plainly that they have chosen the "cause."
For others, it's impossible to entirely discount the presence of gods and demi-gods. These beings have such power that even the unwilling can easily be drawn into their manipulations and interventions in world affairs. In addition, temples, shrines and holy sites abound. These locations often serve as centers of community life, hubs of information and sources of magical or divine power, as well as a means by which adventures may restore the lives or vitality of their fellows. Religion is an integral part of the setting; it offers opportunities for adventures and sets boundaries that even the most resistant of players must often observe.
