Excalibur has been stolen — not by a rival king or a traitor knight, but by raiders from the far future who have no intention of returning it. As Merlin's apprentice, you are the only available solution. Armed with little more than a broadsword and a limited capacity for spellcasting, you are sent forward to the year 2555 A.D. with a mission that could not be simpler to state and could not be harder to complete: find Excalibur, take it back, and prevent the catastrophe its absence would cause.
