After King Arthur's many adventures his son, Mordred, seized his kingdom and queen, forcing Arthur to fight for what was truly his. They fought for a long time and Mordred hit King Arthur in many places, but in the end it was Arthur who killed Mordred. After this victory, King Arthur was weak and died from losing blood from the wounds received in the battle. As his knights rode back to Camelot, they threw Excalibur into the lake so that it could return to where it came from. One legend is that he never died but will return when the British need him.
