In the show, we know Marie as a present-day version of herself who owns a hair salon and is over 200 years old. Since 1801, she's been in a constant quarrel with the witches and horrific past figures of New Orleans. In real life and on the show, Marie was known as the "Vodou Queen." Aside from that, we see a very different version of Marie play out in the show from how we know her in reality. In the show, at the height of her power, she became pregnant with her first child by her lover, Bastien (a house slave for Madame Delphine). However, she couldn't accept death, and when Papa Legba showed up, she sold her soul to him in exchange for immortality and "performing a service" for him once a year. Once her child was born, she found out that she had to offer up the souls of innocents to keep her immortality, beginning with her child.
