Lord British has declared a time of celebration to mark the reconstruction following the moongate plot. Suddenly, the Guardian appears, trapping Castle Britannia and all those inside within the Blackrock Dome.
The Avatar descends into the sewers beneath the castle and discovers a mysterious jewel capable of allowing travel to other worlds that have previous been conquered by the Guardian. The Avatar weakens the jewel and seeks a means of destroying the Dome.
Just as the Guardian and his champion Mors Gotha begin the invasion of another world, the Avatar solves the mystery of the jewel and the Dome. Slaying Mors Gotha, the Avatar is able to shatter the Dome - freeing the Britannians and closing the gateway between worlds.
