The first name of Assassin's Creed Unity protagonist Dorian is Arno.
Arno Victor Dorian is a French Assassin whose story unfolds during the French Revolution. He is raised in the household of a prominent Assassin before a personal tragedy draws him into the Brotherhood and into a search for the truth behind a murder.
Unity begins in 1776 and later moves into revolutionary Paris. Arno's investigation brings him into contact with both Assassins and Templars, including Élise de la Serre, a Templar and his childhood companion. Their relationship gives the story a personal connection that runs alongside the wider political upheaval.
Arno is sometimes confused with other French characters in the series, particularly Élise, who is important but not the playable protagonist. He is also distinct from Arno's father, Charles Dorian, whose death occurs before the main events of the game. Unity introduced cooperative multiplayer missions in addition to its single-player campaign.
