Queen Táriel is the Keeper of the Water Element in the Fifth Age.
She is the reincarnation of the original Naiad leader, Alu.
*** Fifth Age Spoiler Warning***
Back before even the First Age, existed 5 ancient breeds of Pae'il. They were pure, having been born of magic. Each breed had a chosen leader, destined to be the keeper of the very element in which they were born of.
War hit and the Angels and Demons wanted the power of the Ancients, so they slaughtered the leaders, one by one, hoping to find the source of their power.
Before she was killed, the Keeper of the Void(magic-5th element) vowed to protect the unborn of the ancient breeds, and she cast off the Naiad pearls(eggs) far from Telrunya and the ever watchful eyes of The Guardians.
In more recent times, the once floating island of Telrunya was pulled from the sky, landing in the middle of the sea. Most assumed the magic that held the island up merely grew weak.
But the prophecy was merely playing out: The Naiads were being reunited, for it was the time of peace.
Among those hidden pearls, was the destined ruler of the Naiads, Queen Tariel.
That was only a teeny tiny part of the story. If you are involved with Fifth Age, please do not post the spoilers.
