Oberon
The name Oberon is first attested to in the early 13th century "chanson de geste" entitled "Les Prouesses et faitz du noble Huon de Bordeaux", wherein it refers to an elven man of the forest encountered by the eponymous hero. Huon, son of Seguin count of Bordeaux, passed through the forest inhabited by Oberon. He was warned by a hermit not to speak to Oberon, but his courtesy had him answer Oberon's greetings, and so gain his aid in his quest. Huon had killed Charlot, the Emperor's son, in self-defense, and so he must visit the court of the amir of Babylon and perform various feats to win a pardon. He succeeds only with Oberon's aid.
