When the mysterious White Knight (Lancelot) arrives from the continent, Guinevere is instantly smitten. The young Lancelot first joins the Queen's Knights to serve her. Lancelot refuses the love of other ladies and sends Guinevere the redeemable knights he has defeated in battle and who must appeal to her for forgiveness. Following his early rescue of Guinevere from Maleagant (in "Le Morte d'Arthur" this episode only happens much later on) and his admission into the Round Table, and with Galehaut's assistance, she and Lancelot begin an escalating romantic affair that in the end will lead to Arthur's fall. In the Vulgate version, the lovers spend their first night together just as Arthur sleeps with the beautiful Saxon princess named Camille or Gamille (an evil enchantress whom he later continues to love even after she betrays and imprisons him, though it was suggested that he was enchanted). Arthur is also further unfaithful during the episode of the "False Guinevere" (who had Arthur drink a love potion to betray Guinevere), her own twin half-sister (born on the same day but from a different mother) whom Arthur takes as his second wife in a very unpopular bigamous move, even refusing to obey the Pope's order for him not to do it, as Guinevere escapes to live with Lancelot in Galehaut's kingdom. The French prose cyclical authors thus intended to justify Guinevere and Lancelot's adultery by blackening Arthur's reputation and thus making it acceptable and sympathetic for their medieval courtly French audience. Malory's "Le Morte d'Arthur", however, portrays Arthur as absolutely faithful to Guinevere, even successfully resisting the forceful advances of the sorceress Annowre for her sake, except as a victim of a spell in a variant of the "False Guinevere" case. On her side, Guinevere is often highly jealous regarding Lancelot's love life, especially in the cases of Elaine of Corbenic and Elaine of Ascolat. Malory goes so far as to suggest Guinevere uses charms or enchantments to win Lancelot's love.
