The malevolent lord of Fors Graviers, an Irish castle. Gawain happened to visit Gaudionés castle on his way to conquer the castle Rigomer. Gaudionés, knowing of Gawain’s prowess, sent a group of maidens to disarm him, knowing that Gawain would not attack them. He threw Gawain in a prison, instructing his sister to torture and starve the knight. Gaudionés’s sister, however, helped Gawain to escape. Gawain later encountered Gaudionés, defeated him, and took him prisoner.
