Fleur

Fleur (Unknown – 31 May 1431) was a young French prostitute who was following the French army led by Jeanne d'Arc during her campaign against the English. In 1429, as an enraged Jeanne was scolding her soldiers for mingling with protitutes, Fleur saw her using her abilities thanks to her own latent abilities.

Convinced that Jeanne was truly an envoy of God, the young woman decided to change the course of her life and to serve the figurehead of the French resistance. While initially reluctant to accept her due to her distaste for sinners and only after her closest confident, Gabriel Laxart, interceded in favor of the girl, Jeanne eventually took her in and gave her a new name, "Fleur".

Utterly devoted to Jeanne and Gabriel, who had become very fond of her, Fleur served as Jeann's maid during all the campaign. Eventually, after Jeanne's capture and trial for witchcraft, Fleur either contacted or was contacted by the Assassin Brotherhood, with whom she devised a plan to save her idol. After an uncouncious Jeanne was smuggled from her cell the day of her execution, Fleur had the Assassins beat her until her face was unrecognizable and took her place at the stake.
