Mordred was Arthur's son, but no one but Morgan knew this and Mordred was raised as Arthur's nephew. Again, Morgana's plan was to become a queen and repair the injustice she had suffered when her father, the Duke of Tintagil, was killed by the army of King Uther, Arthur's father. Being Mordred son of King Arthur, as soon as he died, Mordred would assume the throne and Morgana would be its queen. But it was necessary to hasten Arthur's death. then Morgana made Mordred's head, causing him to desire the kingdom for himself.

Therefore, Mordred and Morgana together with Sir Agravaine armed a CONSPIRACY. They knew that Lancelot would leave the court and knew he would not do it without saying goodbye to the queen. Thus Sir Mordred, Sir Agravaine, and twelve other men were left in the throat of Lancelet. When he emerged in the hall, he was attacked by the young men. Even without armor and being taken by surprise, the mature Lancelot overcame his enemies, killed Sir Agravaine and the other twelve men. Sir Mordred fled wounded and ran to King Arthur's quarters to tell the facts.
