So, I'm not sure if they changed it or what the plans are with this first encounter with Auntie's slaves that wear the masks. I remember talking to one of them and there was dialoge where she told me to come see her in Baldur's Gate. I was looking forward to that. Now, I can't seem to get that dialoge again.

I have done this many times and in many different ways. I've pickpocketed the maks off them before going to Auntie, in hopes they might offer help or at least flee. But it just killed them. I've knocked them out instead of killing them, then removed their maks and it killed them. I've knocked them out, killed auntie, then came back and removed their masks and it worked! But they were still unconscience. When I reseted and came back, they were all gone.

I'm hoping there is a way to end up saving these people when release comes. Very interested to find out what happens to them.
