personally I say, just throw money at Charles and let him get whatever he needs. That and try to raise his level so he can go out and get those things he will need
why not try to conquer those realms so they will be his property ?
the energy, ressources and culture from them may even help him and the inn grow more
these ideas of inclusivity are what brought this mess in the first place.
just implement the ideas and if someone doesn't want to do more why should he get the same as those who are willing to.
completely defeats the purpose
