A Knight of the Round Table and the son of Morgause and King Lot of Orkney, making him the nephew of King Arthur. He is the hero of the Pearl Poet's 14th-century romantic epic Sir Gawain and the Green Knight, in which Gawain's loyalty and resolve are tested by the title Green Knight (secretly Lord Bertilak), who survives his beheading at the hands of Gawain and returns a year later to return the favor. Gawain's brothers Gareth and Gaheris are killed during Lancelot's rescue of Queen Guinevere, sending Gawain into a frenzy.
