Gwydyon

The warrior god. Gwydyon was the god of magic, poetry and music.

Gwydyon was the son of Don and Beli. Gwydyon was the son of Amathon, Aranrhod, Gilvaethwy, Govannon, and Nudd. Gwydyon adopted the children of his sister Aranrhod: Dylan and Lleu.

Gwydyon served as the chief adviser of his uncle Math, king of Gwynedd, in northern Wales. He killed Pryderi in single combat over some pigs.

Gwydyon helped Lleu overcome the curses or taboos set by Lleu’s mother (Aranrhod), and rescued his nephew when he was transformed into an eagle.
