You play as Cyrus, a Redguard in search for his sister and a mercenary pirate. After receiving a letter from your old Nord friend captain Tobias about your sister's disappearance, you sail to the island of Stros M'kai – the site of the final clash between the Redguard Crowns and the Empire, and your sister Iszara's last known home. The game begins when you arrive at the port.
In the big box version of the game one would find 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 its cover matches the one of the in-game book that reveals the main menu.
