Countess of the Fountain
Wife of the Lord of the Fountain.
When Owain (Ywaine) killed her husband she married Owain, but renounced him when he spent a year away from her at Arthur’s court. After a number of grueling adventures, Owain was able to return to her graces.
She is known as the Lady, or Countess, of the Fountain in the Welsh Owain, and as Laudine in other tales.
