- The Sovereign Host: nine gods (Aureon, Balinor, Boldrei, Dol Arrah, Dol Dorn, Kol Korran, Olladra, Onatar, Arawai). The common faith of Khorvaire. Most people pray to whichever god fits the moment.
- The Dark Six: the Host’s shadow: the Mockery, the Devourer, the Fury, the Keeper, the Shadow and the Traveler. Worshipped by outcasts and cultists; the Traveler is loved by tricksters.
- The Church of the Silver Flame: Thrane’s faith, but found everywhere. Born when the paladin Tira Miron sacrificed herself to bind a demon lord. Sworn to fight fiends, undead and aberrations, which makes its followers heroes to some and inquisitors to others.
- The Blood of Vol: strong in Karrnath. Believes divinity lies within mortal blood and death is the enemy. Often (unfairly?) linked to necromancy.
- The Undying Court (Aerenal), the Path of Light (kalashtar), the druid sects of the Eldeen, and the Cults of the Dragon Below (madness worshipping the underworld of Khyber).
