Arianrod came to Caer Dathyl to serve as Math, a Great Wizard's Foot-holder, an honor only held by a virgin. Legend states that on the day she arrived for duty she brought with her shame. Arianrod claimed to be a virgin but, on that day, she bore two sons. Disgraced, she abandoned the infants to flee to her castle by the sea. Her first child was a son named Dylan who leaped into the water possibly to avoid the curses from his mother. The second son was rescued by Gwydion. He raised him and passed on his knowledge of magic on to the boy.
Arianrod's choices led her to despair. She became bitter by the experience in her life and swore revenge on all men, even her second son. When Gwydion politely asked her to name her son, she refused. Arianrod denied him a name and would not allow the boy to bear arms or marry. Gwydion tricked her with his magic into naming the child Lleu Llaw Gyffes. Later, Gwydion created an illusion while he and Lleu Llaw were disguised as Bards, of a fleet of mighty warships ready to attack her castle. It was Arianrod herself who armed Lleu Llaw when she was fooled by the vision.
Arianrod's black heart sealed her son's fate. With pure hatred, she cursed her son to solitary bed. She told the pair that Lleu Llaw would never know true love from a woman. Gwydion and the Great Wizard, Math, harnessed their magical powers together to help Lleu Llaw overcome the curse. They conjured up a bride from flowers, herbs, bark, spring water and the energies of the Sun and Moon cycles. When the flower woman came to life the wizard named her Bloodeuwedd or Flower face, then gave her to Lleu Llaw to wed. Gwydion and Math believed the curses were overturned.
Arianrod's choices in her life affected many people who were connected to her. The choice she made in the past had a consequence which then had a great impact on her future. Her life turned at an accelerated rate. He fortune rose and fell. She gained and lost, was of discord, destruction and despair.
The dark side of her nature created her bleak reality. Her reactions affected the cycle of events. She had three opportunities to change and improve the situation. She could have taken steps to turn from selfish person into one who helped others. Instead, the events which took place were episodes of misfortune because she refused to follow the Law of Karma, a witches rede:
BIDE THE WITCHES LAW YE MUST,
IN PERFECT LOVE, IN PERFECT TRUST,
EIGHT WORDS OF THE WITCH'S REDE FULFIL,
AN YE HARM NONE, DO WHAT YE WILL,
WHAT YE SEND FORTH COMES BACK TO THEE,
SO EVER MIND THE RULE OF THREE.
FOLLOW THIS WITH MIND AND HEART,
AND MERRY YE MEET AND MERRY YE PART.
