Lamashtu

Lamashtu is the goddess of nightmares and aberrance. She was the first demon lord to achieve true godhood. After murdering Curchanus, a now mostly forgotten god of beasts, travel, and endurance, she wrested his dominion over beasts from his dying body to gain divinity. Now, she's revered as the Mother of Monsters and the Queen of Demons. Legends say that nearly all Golarion's foul creatures sprang from her polluted womb. Loathsome monsters account for most of her worshippers, though she also resonates with individuals who consider themselves outcasts from the world or seek to transform all mortalkind into ravenous beasts.
