The world of Golarion is full of ancient secrets, hidden lore, and untapped psychic powers. Pathfinder Campaign Setting: Occult Realms helps Game Masters explore occult themes in their games, providing inspiration, new rules, and detailed locations to bring an occult campaign of any level to life. New occult powers designed to complement the new classes presented in Pathfinder RPG Occult Adventures help members of psychic classes customize their characters through story-based accomplishments, and new rituals tied to the organizations, history, and gods of the Inner Sea region allow non-psychics to create powerful occult effects. More than a dozen locations rife with occult adventure potential are detailed within, including sites in Hermea, Jalmeray, Numeria, and Razmiran, as well as sites on other planets and planes of existence. No occult-themed campaign in the Pathfinder campaign setting is complete without Occult Realms!
