Theism involves the worship (usually involving sacrifices of one kind or another) of a Pantheon of gods, and the resulting magic that can be gained through such worship.

• Each Diety within the pantheon has one or more Affinities, such as "War", "Healing", "Growth", et cetera.
  • Each affinity contains within it specific Feats -- magical abilities which some Theists can learn to perform (requires Concentrated worship), which replicate events within the myths of the Diety.
  • Greater gods have multiple Aspects ("Faces", Identities, etc.) -- each aspect with it's own set of Affinities and Feats. Common Gods have a single set of Affinities and Feats. Demi-gods might have only a single Affinity and related Feats, while Daimons may have only a single Feat they are known for.

It should be noted that each aspect of a great god has it's own cult. Such that one cannot have all sets of affinities for a great god, but just the three for the aspect in question.

Working with the Issiaries folks, I've learned that three is the maximum for any cult, BTW.
