Have you redeemed her yet? She thanks you for pulling her back from the brink and reflects on what she almost did.
I did, and Olodan and her cabal just up and disappear lol. As if they are only there so you have something to fight during the confrontation scene when you know Kagha is a shadow druid. In my first "kill Kagha" run on Zevlor's behalf I thunderwaved the three mice (who were throwing fire and acid at me...) and these three people popped out of thin air. Druids are not a good narrative vehicle for the story they want to tell with the Tieflings and I have a sneaking suspicion that once we get to Baldur's Gate they will just do this one all over again with the townsfolk there.
