Gareth

Sir Gareth was a Knight of the Round Table in Arthurian Legend. He was the youngest son of Lot and of Morgause, King Arthur's half-sister, thus making him Arthur's nephew, as well as brother to Gawain, Agravain, Gaheris, and half-brother to Mordred. He is the subject of Book VII in Sir Thomas Malory's Le Morte d'Arthur, which tells how he became a knight.
