I like Kahga as a heel. I think her facial capture work is really good for it. I agree that the food shortage thing is a bit much given the existence of conjure food. I still think the conflict is fine generally.
I feel like the kid should just end up captured and I feel like her being killed is a real lame way to force the player into a conflict he can't handle. I feel like the child dying should be more from some attempt to rescue or failed acrobatics roll or something like that. Though other than that I don't have a huge issue with the conflict, I do have a problem with both sides being surprisingly fine with genocide of the other.
