Taltos

In the third chronicle of the Mayfair Witches, the Talamasca seek to preserve the nearly extinct Taltos race by bringing together a male and female. Their searching catches the attention of an ancient Taltos named Ashlar entwined with Lasher's identity. Ashlar reveals the taltos mythology and lineage and enlists the help of Michael and Rowan in his battle againsst evil.
Ashlar longs to make right the sufferings of his people. To help Ashlar, Michael must keep his coupling with Mona Mayfair (a precocious teenager who loves sex and computers equally) a secret, for it has produced a new female Taltos. Rowan attempts to assist him, but the task is difficult given that Morrigan, the Taltos, has been named the heir to the Mayfair fortune. Morrigan becomes the new monster of the Mayfair family.

Interesting Fact:
When Ashlar recounts his history, he details the persecution of the Taltos by the Celts, and the necessity of the Taltos taking cover as a tribe of humans called the Picts. The Picts were an actual tribe in Britain. Anne was intrigued by them because they ruled Scotland for centuries and then disappeared, leaving only some strange artifacts to prove they ever existed.
