Jeanne d'Arc, the Standard-Bearer who Correctly Guides the Holy Grail War, is the Saint of Orléans. A Catholic Saint born in 1412 in Domrémy, France, and the heroine of France who liberated Orléans in the Hundred Years' War.
Fate/Zero
Jeanne is referenced by her former comrade Gilles de Rais, who, in his crazed mind, mistakes Artoria Pendragon for Jeanne. He believed that his wish of bringing Jeanne back to life was granted by the Holy Grail, and he succumbs to tears. He believes Artoria's denial of Jeanne's identity is a curse laid upon her by God, that her heart has been sealed through her devotion. She who gave everything to God was not given salvation by Him, so he wishes to "free" her by proving that no such God exists. Recalling his past while bathed in the annihilating light of Excalibur, Gilles remembers events before he began his forays into murder and the occult, back when he still served alongside Jeanne d'Arc. She is shown standing at a church altar and turns back to Caster and reaches her hand out to him, making him realize the transgressions of his life before he is destroyed.
Fate/Apocrypha
Jeanne is summoned under strange conditions as the Ruler servant. Although she is to act as the impartial mediator, she feels a foreboding that there is someone unknown she must encounter that takes precedence. Rather than being given a spiritual body, she possesses a human girl named Laeticia, a willing host. After the Homunculus receives the heart of Siegfried, Jeanne offers to watch over the Homunculus herself. She intended to guide the Homunculus, who names himself "Sieg," into carving out a new life for himself. However, Jeanne would later find Sieg participating in the war despite her insistence that he could live a normal life instead. Jeanne encounters her unknown, Shirou, who is revealed to be the 'first Ruler', and questions his motives and becomes disgusted by his selfish ambitions to force humanity to accept salvation they had never asked for. Upon reaching the Holy Grail, she encounters William Shakespeare. He torments her psychologically using his Noble Phantasm, but it isn't until he shows her Sieg being burnt at the stake that Jeanne nearly breaks. Shakespeare goes as far as to summon a real Gilles de Rais, a former comrade of Jeanne's. They both torment Jeanne over her romantic feelings for Sieg. She tries to deny any attraction to Sieg due to her vow to love everyone equally. Jeanne eventually faces off against Shirou, with Sieg and a reformed Gilles by her side.
Jeanne decides to use her Noble Phantasm, La Pucelle, at the cost of her own life. Jeanne fails to do much beyond cost Shirou an arm, and Jeanne dies in Sieg's arms. She leaves behind the body of her vessel, Laeticia. Sieg later transforms into the dragon Fafnir and transports the Holy Grail to the Reverse Side of the World so that Shirou's wish will not come true. An unspecified amount of time later, Jeanne manages to travel to the Reverse Side of the World from the Throne of Heroes. She reaches Sieg and reverts him to human form. They decide to travel together, and she finally confesses that she loves him.

After Goetia is defeated, Jeanne thanks the disappearing Servants for holding the Demon Gods back so Ritsuka and Mash can reach the throne.
