Of Circles and Cycles by Anérea

"Of the Wise some were women, and they were greatly esteemed among Men, especially for their knowledge of the legends of ancient days. Andreth was a woman of the House of Beor, the sister of Bregor father of Barahir (whose son was Beren One-hand the renowned). She was wise in thought, and learned in the lore of Men and their histories; for which reason the Eldar called her Saelind, 'Wise-heart'. Another Wise-woman was Adanel, of the People of Marach, whose lore and traditions, and their language also, were different from those of the People of Beor. But Adanel was married to a kinsman of Andreth, Belemir of the House of Beor: he was grandsire of Emeldir, mother of Beren. In her youth Andreth had dwelt long in Belemir's house, and so had learned from Adanel much of the lore of the People of Marach, besides the lore of her own folk."
