Hygwydd

Hygwyd

A servant of Arthur assigned the task of bearing the magical cauldron that Arthur seized from Diwrnach the Irishman.

Hygwydd later accompanied Arthur’s party to the cave of the Black Hag in the Valley of Distress. Hygwydd and his brother Cacamwri were the first warriors to enter the cave, and they were both mauled, stripped, and thrown out of the cave screaming by the Black Hag.
