Most major Theistic deities have up to three Affinities -- large categories of interest of influence to the deity. Each Affinity can be learned by the Initiate or Devotee (and can be used as passive augments on the generic category of activities they encompass). In addition, each Affinity contains 'below' it several specific Feats that can be used as Active magic if learned. (Feats can only be learned by Devotees.)
