A king who conquered Wales and North Wales from Queen Herzeloyde, Perceval’s mother, in Wolfram’s Parzival, after Gahmuret's death. His brother was Duke Orilus of Lalander and his sister was Cunneware of Lalant.

He stole a strong horse named Gringolet from the Grail Knight (Templars) Lybbeals, and the horse eventually was owned by Gawain.

His name may be a German form of the Welsh Llewellyn.
