Sir Gareth
In the stories of King Arthur, Sir Gareth is a member of the Round Table. He is the youngest child of King Lot and Queen Morgause, King Arthur's half-sister, and as such, he is Arthur's nephew. He is also the brother of Gawain, Agravain, Gaheris, and perhaps Mordred's brother or half-brother. Gareth is most noteworthy in Le Morte d'Arthur, when he also goes by the moniker Beaumains.
Sir Gareth was born with royal blood. He appeared as a figure in Malory's seventh book and was given his own chapter, "The Tale of Sir Gareth and Orkney," in which he recounted how he became a knight.
He initially entered the royal kitchen undetected as a layman, a fair child with no known identity or history. Sir Kay, the same person who made fun of him and called him "Good Hands" or "Beaumains," hired him. Then, in the course of events, he is discovered saving Lyonesse, wed to her, and winning the Red Land conflict alongside vivid Knights and other characters. While ruthlessly defeating other knights, he saved their lives in exchange for a lifelong vow of service to King Arthur. This incident illustrates his devotion to the King and his unflinching character.
Sir Gareth was a traditional hero, and even in contemporary plays and movies, he continues to play a significant role.
