The Green Knight urges Gawain to keep the sash as a token of their struggle and invites him back to the castle to celebrate the New Year. Gawain declines and considers the dangerous wiles of women . He agrees to keep the girdle to remind himself of the "fault and frailty of the foolish flesh." The Green Knight reveals himself to be Bertilak de Hautdesert, servant to the sorceress Morgan le Fay. It was Morgan who engineered the entire game, sending Bertilak down to Camelot so that Guinevere would be shocked to death by the staged beheading. In fact, Morgan was the ancient noble lady at Hautdesert castle and is the scheming half-sister to Arthur, the king's traditional nemesis. A disillusioned Gawain returns to Camelot, where is greeted with much cheering and joy from Arthur, Guinevere, and the others. He recounts his entire adventure, but is ashamed when he tells of his ultimate failing as a result of the green girdle. Nevertheless, Arthur and the courtiers, unaware of Gawain's shame, adopt the green girdle as a heraldic token in honor of Gawain. From there, the poet concludes in much the same way he opened the poem, praising Arthur, moving back through Brutus to the siege of Troy. The final two lines implore Jesus Christ for bliss.
