WHY DID ARTHUR GROW UP WITH SIR KAY AND HIS FAMILY?

Arthur grew up with Sir Kay and his family because he was raised as a ward by Sir Ector, Kay's father. After the death of Arthur's biological father, Uther Pendragon, he was hidden away to protect him from potential threats to his life. Sir Ector and his family provided a nurturing environment, allowing Arthur to grow up unaware of his royal lineage until his destiny was revealed. This upbringing also serves as a pivotal element in his development and eventual rise to kingship.
