In a couple of places Vlad mentions he is aware that Morrolan has a circle of witches at Castle Black. However, it doesn't seem that he has any notion as to the extent of the circle. This would seem to be a little odd given Vlad's role in castle security. Either Vlad is very incurious in this case or Morrolan doesn't want him to know for some reason. It will also be interesting if Noish Pa becomes aware of the extent of the circle. Steven Halter
