The Lady of the Lake Had a Secret
The Lady of the Lake had a secret. It was nothing mortifying or dangerous, but it might have caused difficulties if certain persons discovered that behind the veils was a maiden younger than Mathilda. Mortals, especially men, needed to see an aged face before they would believe in either power or wisdom.
Her name was Etaine. It was not something she shared with the world, any more than her face or her manifest youth. When she walked abroad from the lake of Avalon, she walked veiled, stately, and mantled in mystery.
Mathilda did not make the mistake of discrediting her wisdom because she had, at the most, fifteen summers on this side of the Otherworld. She remembered who she had been. Her knowledge passed from world to world, life to life, Lady to Lady, back beyond Morgaine and Rhiannon to lives so ancient that even bards had forgotten them.
