Supplement IV: Deities, Deminities & Personalities

A supplement for the Avremier old-school fantasy setting focused on divine powers, religious culture, and the afterlife. It details human churches and leaders, non-human devotees, the heretical Reliquarian class, and variant druid sects devoted to metal, poisonous plants, and fungus. The book includes more than 20 divine and druidic spells, entries for deities and other supernatural beings, over 30 divine magic items and relics, and rules covering holy days, observances, death, and returning from the dead.
