make him earn the trust of knights Leodegrance and Uryens, who swear fealty to the young king. During this time, Arthur also meets Guinevere and is smitten by her. Later, the undefeated knight Lancelot blocks a bridge, seeking a king worthy of his sword. He defeats the king's knights and gets challenged by Arthur to a fight. With the aid of Excalibur and the Lady of the Lake, Arthur is victorious, and Lancelot swears allegiance to him. Arthur and his knights unify the land. Arthur creates the Round Table, commissions the building of his castle Camelot and marries Guinevere. Meanwhile, his half-sister Morgana becomes apprenticed to Merlin. Influenced by Morgana's magic, Gawain accuses Guinevere of treachery and a duel over her innocence is set. While Arthur is judge of the trial, Lancelot fights for her honour and wins. Guinevere is moved by this and the two make love. Arthur finds out about it and spitefully thrusts Excalibur into the ground between them. Merlin's magical link to the land impales him on the sword, and Morgana seizes the opportunity to trap him and steal his secret Charm of Making. Taking the form of Guinevere, she seduces the unknowing Arthur. She later births a son, Mordred, whose incestuous origin strikes the land with famine and sickness. Struck by a magical bolt of lightning, Arthur is reduced to a weakened state. He sends his knights on a quest for the Holy Grail in hopes of restoring the land and himself. While searching, many knights die or are bewitched by Morgana into entering her service. After reaching adulthood, Mordred demands Arthur's crown, to no avail. Before coldly rebuking Arthur's attempt to recognize him as his son, Mordred vows to return with an army and take Camelot by force. Perceval resists Morgana's attacks and, before long, he is the final remaining knight questing for the Grail. Along the way, he nearly drowns and is transported to where the Grail is kept. He proves worthy, gains the Grail and takes it back to Arthur, who drinks from it and is revitalized, along with the land. Arthur calls upon his step-brother Kay to rally his remaining forces to battle Mordred and Morgana. Arthur finds Guinevere at a convent, and they reconcile. She gives him back Excalibur, which she had kept, and he rides off with his men. At Stonehenge, Arthur falls asleep, and his love liberates Merlin
