Shay Patrick Cormac was formerly a devoted member of the Colonial branch of the Assassin Brotherhood. But after accidently causing a natural disaster during a mission for the assassins, killing thousands of innocent lives he became disillusioned of their cause and reason.
Stricken with guilt, he turned against the Brotherhood and soon joined The Templar Order. There he vowed to hunt down his former allies to stop them from hurting any more innocent lives.
Shay Cormac was the captain of The Morrigan, a well-equipped ship armed with state-of-the-art weaponry he used as a privateer for the British navy during the Seven Years' War and in his pursuit for The Assassins.
Shay Cormac is the main character of Assassins Creed: Rogue and is the second playable Templar in the series. His voice and motion was performed by Canadian actor Steven Piovesan.
