You play as Cyrus, a Redguard in search for his sister, and a mercenary pirate. After receiving a letter from your old friend and Nord captain Tobias about your sister's disappearance, you sail to Stros M'kai, your sister's home, and site of the final clash between the Redguard Crowns and the Empire. The game begins when you arrive at the port.
The big box version of the game contains a 93-page booklet, an addendum, a warranty card and an A3-sized map of Stros M'kai. The booklet features a comic about Cyrus' life prior to the game's events, as well as a 'Pocket Guide to the Empire and its Environs', which describes the histories and cultures of different parts of Tamriel, accompanied by small maps and character art.
The booklet is called 'The Elder Scrolls Adventures: Volume R,' and so is the book that opens in the game to show the menu.
