scarcely make peace between Kai and Arthur. And thenceforth, neither
in Arthur's troubles, nor for the slaying of his men, would Kai come
forward to his aid for ever after.


Said Arthur, "Which of the marvels is it best for us now to seek?"
"It is best for us to seek Drudwyn, the cub of Greid the son of Eri."

A little while before this, Creiddylad the daughter of Lludd Llaw
Ereint, and Gwythyr the son of Greidawl, were betrothed. And before
she had become his bride, Gwyn ap Nudd came and carried her away by
force; and Gwythyr the son of Greidawl gathered his host together,
and went to fight with Gwyn ap Nudd. But Gwyn overcame him, and
captured Greid the son of Eri, and Glinneu the son of Taran, and
Gwrgwst Ledlwm, and Dynvarth his son. And he captured Penn the son
of Nethawg, and Nwython, and Kyledyr Wyllt his son. And they slew
Nwython, and took out his heart, and constrained Kyledyr to eat the
heart of his father. And therefrom Kyledyr became mad. When Arthur
heard of this, he went to the North, and summoned Gwyn ap Nudd before
him, and set free the nobles whom he had put in prison, and made
peace between Gwyn ap Nudd and Gwythyr the son of Griedawl. And this
was the peace that was made: --that the maiden should remain in her
father's house, without advantage to either of them, and that Gwyn ap
Nudd and Gwythyr the son of Greidawl should fight for her every first
of May, from thenceforth until the day of doom, and that whichever of
them should then be conqueror should have the maiden.

And when Arthur had thus reconciled these chieftains, he obtained
Mygdwn, Gweddw's horse, and the leash of Cwrs Cant Ewin.
