Witch's Coven or Witches Coven

[Gynn]

Well, which witch is it? :D

They both sound right, although "witch's coven" seems to imply that only one witch owns the coven (very selfish). I'd use "coven of witches", but it doesn't fit right in the sentence.

If it's a coven belonging to more than one witch: Witches' coven

If it's a coven belonging to more than one witch: Witches' coven
And there you have it.
