AC's cast of playable protagonists (the one through which users experience the storyworld) are fictional. On their quests, they meet such fascinating historical figures as Richard the Lionheart, Leonardo da Vinci and Niccolò Machiavelli, George Washington, Benjamin Franklin, and Benedict Arnold, Napoleon Bonaparte, Maximilien Robespierre, and the Marquis de Sade.
There is only one woman character in Assassin’s Creed Unity: Elise de la Serre. She, too, is fictional, the childhood friend and sometime love interest of the main, and only playable character, Arno Victor Dorian. Now we’ll admit she is no shrinking violet. She brandishes a weapon along with Arno, being on a revenge quest of her own. And while she cuts a very sexy figure, she does appear on screen fully clothed.
But to be a non-playable character means that Elise cannot act upon the storyworld. She's merely window dressing, part of the background story, scripted and fed to us whenever we, as Arno, wander down the appropriate rabbit hole that, like Dumbledore’s pensieve, triggers the memory that Arno, and we, need to collect the clues and knowledge necessary to complete his mission.
