Kagha would certainly be interesting choice for companion ...
But also completely ilogical. :-/
Either she is evil, and therefore she cares about nothing but her own Druid circle.
Or she is redeemed, amd therefore she stay in the Grove waiting for her punishment.
How would you like to fit joining our party to her story? O_o
Nettie would make much more sence, after all she wanted to find Halsin and while she is "too weak" to pursue him by herself, she could accept our help as bodyguards.
Also that mention of having both Kagha and Minthara in camp ...
I would like to know how you want to achieve that, since they both want to kill each other. O_o
I still dont understand why cant we change Race for our hirelings.

Lets us play Githyanki as racist as they trully are!
