give her a coven, the witch hex requires a hag, since she's the hag giver her some 'sister' witches. Maybe one of the sisters is a changeling who poses as a bugbear, has the leadership feat and has a bugbear clan convinced she's their leader, when she's not even really a bugbear.
Make the other witch something interesting,un suspected.... maybe a halfling with the pass for human feat and the childlike feat, so you think it's a 9 year old girl?
