Arno Dorian is the protagonist of Assassin's Creed Unity, set in Revolutionary Paris.
Arno is a French Assassin whose life changes after the death of his adoptive father, François de la Serre. He joins the Parisian Brotherhood while pursuing answers about the conspiracy surrounding the murder.
The game is set during the French Revolution, beginning in 1789 and using locations such as Paris, Versailles, and the Bastille. Arno's personal relationship with Élise de la Serre is central to the plot, but Élise is not the player character.
Jacob and Evie Frye belong to Assassin's Creed Syndicate, which takes place in Victorian London. Arno Dorian is specific to Unity and should not be confused with other French characters in the series.
