In Assassin’s Creed Rogue, what is the full name of the protagonist who defects from the Assassins?

The Assassin’s Creed Rogue protagonist who defects from the Assassins is Shay Patrick Cormac.

Shay begins the game as a member of the Colonial Brotherhood during the eighteenth century. After a disastrous mission involving an ancient artifact and an earthquake, he becomes disillusioned with the Assassins’ methods. He eventually joins the Templar Order and hunts former allies who remain in the Brotherhood.

Rogue is notable because it places the player on the Templar side of the series’ long-running conflict. Shay’s perspective revisits characters and events connected with Assassin’s Creed III and Assassin’s Creed IV: Black Flag, including figures from the Kenway-era storyline.

Arno Victor Dorian is the protagonist of Unity, while Edward James Kenway leads Black Flag. Jacob Frye is one of the protagonists of Syndicate. Shay’s full name is therefore the precise answer, not merely his first name or the name of his former faction.
