In the story I have heard, Sir Mordred was supposedly Arthur's Son/Nephew. Merlin Prophesied that Arthur's son would kill him. Arthur sent Mordred out with 40 other babies to die afloat in a coracle out in the sea. Mordred was the only Survivor, grew up in Lothe, and became a knight of the round table. He did fulfill his destiny. He killed Arthur while Arthur killed him.

She tried on multiple occasions to kill her brother, King Arthur as her jealousy of him being crowned King grew upon her on several occasions. All of her trials to kill King Arthur were failures and instead he was killed by his brother, Sir Mordred who is also known as Sir Mordred the Traitor as his brother King Arthur betrayed him in a fight.
Mordred was the son of King Arthur and the sorceress, Morgan la Fey. As an adult, Mordred was Arthur's chief enemy and the person who killed him in battle.
