Dion Fortune

Dion Fortune (ダイアン＝フォーチュン) is a posthumous character introduced in Shinyaku Toaru Majutsu no Index.

Appearance
When reproduced, Dion Fortune appears as a short, skinny girl with short red hair, white skin and a small build. She wears frilly white dress with pink accents and the star decorations typical of Golden Dawn members, with exposed arms, and purple leggings and thick soled shoes, without which she be less than 150cm tall. She also wears a frilly collar with a star decoration, frilly cuffs and a hair decoration combining a white flower and a veil. She carries a black box made of a smooth material and about big enough to hold a football.

Due to her ballerina-style dress with lace and frills, and her hair decoration, her silhouette is described as fluffier than normal, reminiscent of an animal bristling its fur or feathers to look threatening when faced with danger.

Background
Dion Fortune was not a member of the original Golden Dawn, but joined its remnants in 1919.

At some point after her death, Dion Fortune was reproduced along with other members of the Golden Dawn by Coronzon, through the application of Tarot-based grimoires, as part of her anti-Crowley countermeasures.

Aleister Crowley Arc
When Kamijou Touma was being shown a recreation of Aleister Crowley's past in the Windowless Building, Dion Fortune's name was brought up during the downfall of Golden Dawn.

Abilities
Rather than planned and calculated spells, Dion Fortune specializes in randomized magic. She claims to use up old and inefficient traditions to rebuild them as a smarter new spell, but she actually doesn't know what kind of magic will result from her method. The grimoires she compiled were apparently beyond what the defenses of the Golden Dawn remnants could handle and some cabal magicians speculated their teachings might have moved beyond what the original ones covered.

Fortune utilizes this magic through the black box she carries with her (which can also float above her hand). After inserting an item of magic, such as a rose cross medal, into the box and closing the lid as if to chew it up, she speaks the command; "Translate, simplify, and create anew!!". The spell is transformed and corrupted within the box, such that when the box is opened, even she cannot predict what kind of magic will come out.

Effects produced with the black box and a rose cross medal include:
 * A mass of flames spewing from the box, used like a booster to propel with thrust or alter trajectory, and was also raised like hammer.
 * Something like translucent umbrella, used to deflect a shockwave spear.

Rather than the stage play ceremonies and groupwork to construct a single piece of magic associated with the Golden Dawn, Fortune tends towards adlibbed oddities, not making plans, only using what she happens to draw from her box and usually not relying on a single spell. The unpredictability from the random phenomena (which not even Waite's cards can fully predict) is is Fortune's greatest weapon, intended to bring down enemy strategy and tactics, ruining calculations and plans made in advance through unexpected actions, and bringing chaos to the battlefield. While Fortune has found victory using her method in the past, it is bad against beings beyond a certain threshold of power, who cannot be defeated with nothing more than luck and the use of probability instead of ingenuity.

Aside from the black box and a worn rose cross medal, the reproduced Dion Fortune also carried a bell on a string which was apparently meant to act as a signal.

Trivia
