Plot
The Castle of King Arthur is put on high alert as someone begins to approach the castle. Watching intently are Mordred and Morgan le Fay, who quickly recognize the man approaching as Sir Percy, Mordred's nephew. Seen as no threat, Percy is allowed to enter the castle and seek an audience with King Arthur due to his noble blood, but none of those gathered are overly impressed by the man who appears to be a weakling. Meeting with King Arthur, Sir Percy explains that he has come to seek a boon from the King for shelter after his lands were taken over by the Baron of Emsore. The King allows for this, but all are disgusted by Percy's cowardice when he tells them that he does not seek to reclaim his land. King Arthur agrees to allow Sir Percy to stay in the castle and assigns Merlin, his court magician, to show Percy to a room.
Merlin, having summoned Sir Percy to the castle, takes the young man to his quarters and thanks him for playing the part of a foppish coward in order to act as his secret agent in stopping Mordred from taking over the castle, explaining that King Arthur does not believe Merlin's warnings. As part of his mission, Sir Percy is given a suid of armor and is christened the Black Knight. Merlin tells Percy that he must act as the realms masked champion and that none should know his true identity. Suddenly, some of Mordred's men, having overheard their discussion storm into Percy's quarters and attack, but the Black Knight easily slays them to cover his secret...
