In Assassin's Creed Unity, what is the full name of the game's playable Assassin?

The playable Assassin in Assassin's Creed Unity is Arno Victor Dorian.

Arno is an Austrian-born French Assassin whose story unfolds during the French Revolution. After the death of his adoptive father, François de la Serre, Arno joins the Brotherhood while investigating the conspiracy surrounding that death. His personal search becomes intertwined with the political and social upheaval in Paris.

The name is sometimes confused with Élise de la Serre, Arno's childhood friend and the biological daughter of the man who raised him. Élise is a Templar, not Unity's playable Assassin, although she is one of the story's most important characters.

Unity introduced cooperative missions for up to four players and placed major emphasis on Parisian architecture, crowds, and freerunning. The campaign includes fictional characters alongside historical figures and events from the Revolution. Its title refers to the game's setting and themes rather than to a separate faction called Unity.
