History
Mia started out in the Prim as a succubus, and had sex with men until they died. She once observed a family and wanted to have a child. The Man in Black offered to make her the mother to the son of the Crimson King.

Roland had sex with a demon. A demon took his sperm which was alterned by the Crimson King. The sperm was then implanted into Susannah. Mia then possessed Susannah in order to ensure the birh of Mordred. Mia showed outward signs of pregnancy, though Susannah didn't.

During the night, Mia would possess Susannah in order to make her eat various animals to nourish Mordred. Susannah realized she was being possessed, but didn't know what to do about it. When Roland's Ka-tet was celebrating having defeated the Wolves, Mia possessed Susannah and took her to New York in the year 1999.

Mia and Susannah waited in a hotel room in New York. While there, she and Susannah are able to talk in their dreams, and Mia explained who she is and what she wanted. She and Susannah came to a temporary truce. Eventually, Richard Sayre called Mia to come to the Dixie Pig to give birth.

Mia and Susannah entered a door to Fedic where they were both separated. In Fedic, Mia gave birth to Mordred. Once Mordred was born, he ate Mia alive.
