I didnt read all 9 pages ... But i thought there should be a way to get Minthara without killing the Groove.
If...
you just manage to help Kagha to seal the Groove ... Halsin (even if he survives) no longer cares (or at least he didnt, in EA, not sure if this wasnt changed ... didnt check myself yet) if Goblin leaders die ... So ... logicaly, if you leave her alive ... she should be in Moonrise Towers, failing in her task just as normaly ... right?
I still dont understand why cant we change Race for our hirelings. Lets us play Githyanki as racist as they trully are!
