Mina Mathers

Mina Mathers (ミナ＝メイザース) was a Magician of the Golden Dawn and the wife of one of its Three Founders, Samuel Liddell MacGregor Mathers. Though deceased in the present day, a recreation of her is produced by Reading Thoth 78 in the Windowless Building to remind Aleister Crowley of his trauma.

Appearance
The Reading Thoth 78's recreation of Mina Mathers appears as a young woman, wearing black risqué mourning clothing which exposes her legs and her large breasts. She has long white hair which is covered by her mourning veil. She also has black cat ears and a tail. Her dress has a star motif, with the images of constellations on her veil, dress and stockings, and several large silver stars fastening her dress.

As the recreation was adjusted to a form which Kamijou Touma would be comfortable with, it isn't entirely clear which particular details were down to Touma's preferences rather than being possessed by the original Mina Mathers.

Background
Mina's past isn't fully known however she was a painter who married Samuel Liddell MacGregor Mathers, a co-founder of the Golden Dawn, and was a member of the cabal herself.

Mina's artistic skill gave form to the uncertain inspiration held by the Golden Dawn's magicians and played a key role in the creation of the cabal's ceremonial tools. She also often acted as a mediator to settle things when some of the eccentric members of the cabal, including her husband and Westcott, got into fruitless debates.

Prioritizing the goal of the cabal's magical research like the other magicians, there were days where Mina had to beg her friend Annie for living expenses.

At some point during the downfall of the Golden Dawn, Mina was among the many magicians struck down by Aleister Crowley, doomed to either die or live a cursed life devoid of all possibilities for success.

Aleister Crowley Arc
Though deceased in the present day, a recreation of Mina was used by Reading Thoth 78 to remind Aleister Crowley of his trauma, and guided Kamijou Touma through a series of visions displaying Aleister's past.

Abilities
The exact degree of the original Mina Mathers's skill isn't fully known however the Reading Thoth 78's recreation has displayed some of her abilities.

Mina Mather's primary skill is her art, which has given solid form to the uncertain imagination held by many magicians and her primary tool is a silver palette knife which draws a rainbow line through space. These are the ultimate source that drew, colored and constructed the many cards and ceremonial tools used by the Golden Dawn. Because of this, she has been compared to, who gave fire to humanity.

She is capable of exerting an influence over cats, intentionally and unintentionally, leading to a large number gathering at her feet like a shadow, the likely source of her epithet.

The recreation was also capable of reading thoughts to a certain degree, though it isn't known if the original could.
