Lancelot is a beautiful orphaned son of King Ban of the lost kingdom of Benoïc. He is raised in a fairy realm by the Lady of the Lake while unaware of his real parentage prior to joining Arthur's court as a young knight and discovering his origins. A hero of many battles, quests and tournaments, and famed as a nearly unrivalled swordsman and jouster, Lancelot soon becomes the lord of the castle Joyous Gard and personal champion of Queen Guinevere, to whom he is devoted absolutely. He also develops a close relationship with Galehaut and suffers from frequent and sometimes prolonged fits of violent rage and other forms of madness. After Lady Elaine seduces him via magic, their bastard son Galahad, devoid of Lancelot's flaws of character, becomes the perfect knight who succeeds in completing the greatest of all quests, achieving the Holy Grail when Lancelot himself fails due to his sins. Eventually, when Lancelot's adulterous affair with Guinevere is publicly discovered, it develops into a bloody civil war that, once exploited by Mordred, brings an end to Arthur's kingdom. - Source: Wikipedia
