Arianrhod originates from Welsh mythology and plays an important role in the fourth branch of Mabinogion. Her mother is Dôn and during the story of Mabinogion, she gives birth to two sons, thanks to magic. She would give birth to the first son named Dylan Ali Don after being told to step over a magician's rod in order to test her virginity. Embarrassed and shamed at the court while giving birth to a child in the process, she cursed her second son Lleu Llaw Gyffes with a wife, a name, and the right to arm himself with weapons.
"Welsh goddess who used rainbows to purge violence from the earth."
