Madame Marie

Personality
Marie was a very powerful arcanist, and an extremely neglectful mother. Not a lot is known about her actual personality, though she concealed much from Sam. She seemed to hunger for power, and didn't have the respect that Sam originally thought she did.

She was a terrible parent, regularly ignoring Anna and Kitty, leaving them to feed for themselves as infants, and then treating them with disdain as they grew. She was also vile towards Sam, locking them in their room against their will after a certain point, despite their screams to leave.

Physical Appearance
In their letter, Nagisa's description of Marie when they first met was that Marie was small and unassuming, with a head of mousy hair half-hidden under a silk scarf decorated with stars.

History
As a child, Marie lived with her grandmother. It's not known what happened to her parents, though it is stated that it wasn't good. Marie grew up in the Arcanist's Apothecary, and tried to take it over when her grandmother passed away, but was unsuccessful. She was reportedly not very good at magic, despite studying it obsessively. In her letter to her grandmother, Marie shows that her knowledge of arcane theory was fantastic, but she was 'functionally useless'. The shop shut a few years after her grandmother's death.

At some point, Marie gained an inordinate amount of power, skill unrecognisable in comparison to her younger self. The specifics of how this power was gained are still unclear. She birthed Anna and Kitty, and ran a tarot tent on various beaches and piers around the country. She neglected her daughters during this time period, and one day returned home to them pregnant with Sam. Initially she doted upon Sam, but later on in his life, she treated him as harshly as the other two, sometimes worse.

Marie refused to let Sam be a part of the radio show, but left notes explaining the equipment when she died.

Skills and Abilities
Marie is said to be a good psychic, her full stage title being 'The Illustrious Madame Marie'. She is referred to as being powerful several times by various characters, including Sam describing her as "most renowned Arcanist in the Northern Hemisphere".

To an unknown extent, Marie also seemed capable of conversing with and making deals with Major Arcana.

Relationships
Madame Marie was technically the mother of Sam Enfield, Anna Enfield, and Kitty Enfield, though her parenting was abhorrent. She neglected Anna and Kitty when they were younger.

The three siblings each had very different relationships with their mother. Anna seemingly didn't talk to her long before her death, having rejected Arcanism from her life. Kitty worked for Marie, and Sam held her in high respect, though after her death, his view of her has become far more complicated.

M employed Janet the Tarot Witch, Astrid the Janitor and Salim the Weather Guy as her 'Loyal Assistants' on the radio show. She also employed Sam Enfield as The Post Boy, and Kitty Enfield as The Investigator.

Marie was friends with an arcanist called Nagisa, though the two of them stopped corresponding at some point when Sam was younger. Marie never told Nagisa about Sam.

Marie knew both Oliver Boleyn and Rhytidia Delphus well enough that she reached out to both for aid at different times.
