First, I must commend you for tackling this series. It's bothered me for a long time and I must say you're doing quite a good job with it.

Also: As I was reading "The Mists of Avalon" by Marion Zimmer Bradley, I came across a passage that talked about how priestesses who were chosen by the Goddess had a blue crescent moon tattooed between their brows by Her.

Sound familiar? And here I thought the Mark was a unique, interesting touch to these vampires. For shame, Casts.
