In Assassin's Creed Rogue, Shay Cormac becomes a Templar after a mission goes wrong.
Shay Patrick Cormac begins the game as an Assassin working with Achilles Davenport's Colonial Brotherhood. During an expedition to Lisbon, Shay witnesses catastrophic destruction after taking an Isu artifact from an ancient site. He blames the Assassins for pursuing dangerous Pieces of Eden without understanding their consequences and eventually defects to the Templars.
Rogue reverses the usual player perspective by making a former Assassin the central character in a Templar campaign. Shay hunts members of his former Brotherhood across the North Atlantic, the River Valley, and New York. The game is set during the Seven Years' War in the eighteenth century.
Shay is sometimes confused with Haytham Kenway, who is already a Templar at the beginning of Assassin's Creed III. Rogue's distinctive premise is Shay's personal transition from Assassin to Templar after the Lisbon disaster.
