In an inaccessible solar system, on the planet Avalon, darkness spreads across the continent, consuming all. But through the blackness, a small light emanates, signaling hope. Merlin awakes from her realistic dream in a cold sweat. She recalls an ancient prophecy. She must find the descendant of King Arthur who will draw Excalibur and save them.

Meanwhile on Earth, Arthur is sent off to a boarding school in England. Alone in a strange place he is unaccustomed to, he draws solace in the tales his mother used to read him, King Arthur and the Knights of the Round Table. He imagines a life where dragons and magic dwell, where damsels need rescuing, and where knights stand for honor, valor, chivalry, and uphold a firm code of conduct.

His greatest desire granted, the days of solitude and daydreaming are over. A duty befalls him that he must undertake. Does he have the courage to answer the call? With Excalibur in hand, will he be strong enough to fight for a world unknown and foreign to him?
