I've been trying to give you plenty of reasons to join in the group, and you've rejected everything.  The only reason you haven't had any meaningful interactions is because Ireth has constantly shut out anyone that tried to interact with her, and that's not just because of her personality.  If you want her to rejoin the group, or want something to happen to her while she's gone off on her own to make her want to group up, that's fine.  But I'm through trying to help you get back into this game if you aren't going to do anything to work with me.
