What is the full name of the protagonist who turns against the Assassins in Assassin's Creed Rogue?

Shay Patrick Cormac is the protagonist who turns against the Assassins in Assassin's Creed Rogue.

Shay begins the game as an Assassin operating in the North Atlantic during the eighteenth century. After a disastrous mission and a growing disagreement with the Brotherhood's methods, he leaves the Assassins and joins the Templar Order.

Rogue is notable because it presents the main conflict largely from a Templar-aligned viewpoint. Shay hunts former allies while traveling through the North Atlantic, the River Valley, and New York. His story links directly to Assassin's Creed III, Black Flag, and Unity.

Arno Victor Dorian is the protagonist of Unity, and Aveline de Grandpré stars in Liberation. Jacob Frye is one of Syndicate's two protagonists. Their names are all connected to the franchise, but only Shay Patrick Cormac makes the specific allegiance change in Rogue.
