While his merits on the battlefield earn him a great praise, Mordred continues to gather truth worthy comrades to aid him in his treasonous plans. He just needs to bide his time and wait for the ideal opportunity. If he can fool King Arthur into believing Lancelot and Guinevere are having an affair, Arthur and Lancelot could very well kill each other. His helmet hides his villanious smile as he imagines how easy it will be to ursup the throne.

Mordred or Modred (Welsh: Medraut, Medrod, etc.) is a character in the Arthurian legend, known as a notorious traitor who fought King Arthur at the Battle of Camlann, where he was killed and Arthur fatally wounded. Tradition varies on his relationship to Arthur, but he is best known today as Arthur's illegitimate son by his half-sister Morgause, though in many modern adaptations Morgause is merged with the character of Morgan le Fay. In earlier literature, he was considered the legitimate son of Morgause, also known as Anna, with her husband King Lot of Orkney. His brothers or half-brothers are Gawain, Agravain, Gaheris, and Gareth. The name (from either Old Welsh Medraut, Cornish Modred, or Old Breton Modrot) is ultimately derived from Latin Moderātus.
