Shay Cormac is the Assassin's Creed protagonist whose ship is called the Morrigan.
Shay is the central character in Assassin's Creed Rogue, released in 2014. He begins as an Assassin operating in the North Atlantic but becomes disillusioned after a catastrophic mission and later joins the Templars.
The Morrigan is a fast warship that supports naval exploration in the North Atlantic, river valleys, and other parts of the game's map. Shay's change of allegiance gives Rogue an unusual perspective on the long-running conflict: the player experiences the story as a former Assassin hunting members of his old Brotherhood.
Rogue connects narratively with Assassin's Creed III, Black Flag, and Unity. Haytham Kenway and Achilles Davenport are among the important figures in Shay's story. The Morrigan should not be confused with Edward Kenway's ship, the Jackdaw.
