 is one of Pathfinder's deities.

Description
Lamashtu, also known as "Mother of Monsters", "Mistress of Insanity" and "Grandmother Nightmare", is the goddess of madness, monsters, and nightmares. She is the only demon lord to attain true divinity. She is the mother and patroness of many misshapen and malformed creatures that crawl, slither, or flap on, above, or below the surface of Golarion. Her unholy symbol is a three-eyed jackal head, which may be represented in many ways, and her sacred animal is the jackal.
