Yes, but old, dusty crones, not young, seductive warriors.

All the same, Adric almost became one, and they were at odds during the story. He could count as a "young seductive warrior" there. (what? in 200+ stories, that was the only one that had vampires in it, we're used to stretching things with this show)
