King Arthur Pendragon of Camelot was the son and heir of Uther Pendragon and the only child of Ygraine de Bois, the husband of Queen Guinevere, brother-in-law to Sir Elyan, son-in-law to Tom the blacksmith, the younger paternal half brother of Morgana, the nephew of Tristan de Bois and Agravaine de Bois, and the best friend and master of the greatest warlock and sorcerer ever, Merlin.
According to the prophecies of Kilgharrah, Arthur was destined to unite the land of Albion. As a young prince, Arthur was spoiled, narrow-minded, and arrogant, though good-hearted; as time passed, he eventually matured and became best friends with his manservant, Merlin. This was partially due to his dislike of the way his father ruled, and also because of the influence Merlin had on him.
Arthur tended to have negative opinions about Uther’s harsher policies, particularly his aversion to magic, but during his reign he kept his father’s decree banning magical practice due to his war with Morgana. Arthur’s great conviction is in peace and justice, and during his reign he revived the Round Table and managed to establish peace between the five kingdoms for the first time in centuries.
Arthur died at the hands of Mordred by the shores of Avalon, but, as the Once and Future King, he is destined to one day rise again.
Arthur was born in Camelot to Uther and Ygraine Pendragon with the help of magic by the sorceress and priestess, Nimueh. Unfortunately, Ygraine was infertile, thus incapable of giving birth, but Uther, who was desperate for an heir, went to Nimueh and persuaded her to use her magic to help Ygraine. However, as Nimueh used the power over life and death for Arthur to be born, a sacrifice had to be made for a life to be created and Ygraine died in the process after Arthur was born. As a result of her death, Uther despised magic and had its practitioners executed but kept the true nature of her death secret from Arthur. Arthur also had an older half-sister named Morgana, who was born from an affair Uther had with her mother Vivienne some time before Ygraine's death and probably before their marriage. Arthur grew up with Morgana after Gorlois died, but remained unaware of her true paternity.
