Guinevere later returns to Arthur from Lancelot's castle and is forgiven (Arthur starts to doubt that Guinevere ever betrayed him). When Arthur goes after Lancelot to France, he leaves her in the care of Mordred, who plans to marry the queen himself and take Arthur's throne. While in some versions of the legend (like the Alliterative "Morte Arthure", which removed French romantic additions) Guinevere assents to Mordred's proposal, in the tales of Lancelot she hides in the Tower of London, where she withstands Mordred's siege, and later takes refuge in a nun convent. Hearing of the treachery, Arthur returns to Britain and slays Mordred at Camlann, but his wounds are so severe that he is taken to the isle of Avalon by Morgan. During the civil war, Guinevere is portrayed as a scapegoat for violence without developing her perspective or motivation. However, after Arthur's death, Guinevere retires to a convent in penitence for her infidelity. (Malory was familiar with the Fontevraud daughter house at Nuneaton, and given the royal connections of its sister house at Amesbury, he chose Amesbury Priory as the monastery to which Guinevere retires as “abbas and rular”, to find her salvation in a life of penance.) Her contrition is sincere and permanent; Lancelot is unable to sway her to come away with him. Guinevere meets Lancelot one last time, refusing to kiss him, then returns to the convent. She spends the remainder of her life as an abbess in joyless sorrow contrasting with her earlier merry nature. Following her death, Lancelot buries her next to Arthur's (real or symbolic) grave.
