In [[489]], Sir Hywel led a great tournament to test Sir Clegis before giving assent to marry. Having had many conversations with the young knight, Hywel suspected that he might be a good husband to his daughter. [[Sir Jaradan]] and [[Galam|Sir Galam the Bear]] also took part in the tournament, though Sir Clegis came away victorious, winning a beautiful peregrine falcon as his prize, as well as the chance to meet Sir Hywel's beautiful daughter. Offering her hand to the young knight, Hywel was impressed when Clegis stated that he wished to ensure that the young lady also desired the match. Allowing them to meet, she assented to the marriage and the ceremony took place shortly thereafter.
Sir Hywel was grievously injured in battle against the Cornish forces at Terrabil, and died of his wounds after slipping into a coma from which he never awoke.
