Lamashtu

Lamashtu was a female demon from ancient Mesopotamian mythology, feared for harming pregnant women, infants, and families. She was believed to cause illness, nightmares, and miscarriage, acting independently rather than serving other gods or demons. To protect against Lamashtu, people commonly used amulets of the demon Pazuzu, whose power was thought to drive her away. "I can tell you Lamashtu is fricking cool" - Simon
