Dôn is the divine mother of the Children of Dôn — Gwydion, Gilfaethwy, Arianrhod, Amaethon, and Gofannon — the supernatural family that dominates the Fourth Branch of the Mabinogi and the governance of Gwynedd.
Arianrhod bore twin sons when she stepped over Math's wand to prove her virginity. Dylan Eil Ton fell to the sea and swam away at once, while Gwydion — Arianrhod's brother and the children's father — snatched up Lleu Llaw Gyffes and raised him in secret.
⚠ The Fourth Branch strongly implies Gwydion's paternity through narrative structure and his role in raising Lleu, but never states it explicitly.
Arianrhod laid three curses on her son Lleu — no name unless she gave it, no arms unless she armed him, no wife of any race on earth — and Gwydion defeated each through cunning and illusion, deepening the bitter rift between brother and sister across the Fourth Branch.
Arianrhod dwells in Caer Arianrhod, her island fortress off the coast of Gwynedd, where she retreated after the shame of Math's virginity test and from which she pronounced her curses upon Lleu.
Gwydion, Arianrhod, Gilfaethwy, Amaethon, and Gofannon are the Children of Dôn, the divine family of Gwynedd whose rivalries, enchantments, and transgressions drive the narrative of the Fourth Branch of the Mabinogi.
Arianrhod cursed Lleu Llaw Gyffes with three tyngedau: he would have no name unless she gave it, bear no arms unless she armed him, and take no wife of any race on earth. Gwydion undid each curse through elaborate deceptions.
Math fab Mathonwy summoned Arianrhod to step over his magic wand to prove her virginity as a candidate for foot-holder. She failed the test when two children dropped from her before the entire court of Gwynedd.
