One poem about a group led by this character contains repeated refrains that “except seven / none rose up / from” several fortresses with various properties including “of Hardness” and “of Glass”. This character is said to have “distributed gifts / blood trickled down” in the poem Pa Gur, in which he argues with a doorkeeper alongside Cai. This character leads an ill-fated expedition to Annwn (“AN-un”) on his ship Prydwen (“PRUD-wen”). This character also uses Prydwen to hunt the she-wolf Rhymi because of a demand of the giant Ysbaddaden (“uss-bath-ADD-en”), on behalf of this character’s titular cousin (10[1])(*) Culhwch (“KEEL-hook”). In later works, this character’s illegitimate child with Morgause, who kills him (10[1])at the Battle of Camlann, is called (10[1])Mordred. This son of Uther wields the “Sword in the Stone.” For 10 points, name this mythical king of the Britons who made court in Camelot. ■END■
