Wasn't Hapsin in your camp, after the tiefling party? He gives you the quest to lift the Shadowcurse after a while.
Though that quest is currently very bugged. I can not finish it on my honour run, because of that bug.
Minthara you should have encountered in the goblin camp. She is one of the three leaders,you gave to kill. You can knock her down or ride with ger instead.
