She is entrusted by Merlin to a loyal knight, Sir Ector, who raises her as a surrogate son. When Arturia is fifteen, King Uther dies leaving no known eligible heir to the throne. Britain enters a period of turmoil following the growing threat of invasion by the Saxons. Merlin soon approaches Arturia, explaining that the British people will recognize her as a destined ruler if she withdraws Caliburn, a ceremonial sword embedded in a large slab of stone.
