Cant help the feeling that this is another of yours trolltopics. :-/
But lets presume its not, for a second ... you totally can side with Kagha allready, when you help her drive tieflings out and she then complete her ritual.
There is no reason to fight goblins afterward, since they cant hurt druids anymore, but its still possible.
You still keep talking like whole world is just waiting for you ... you get there by accident called ship crash, every NPC have allready his own plans and motivations, you simply just happened to be around, nothing more ... deal with it. :-/
I still dont understand why cant we change Race for our hirelings.

Lets us play Githyanki as racist as they trully are!
