Don't know if anyone thought this up already, but how about being able to, according to alignment, HIRE some aid?
It would work like charm, only for a price, if you were Good aligned, you could hire Silvermere guards to follow you and they would fight along side you.
Have different people you can hire for each alignment.
We've discussed this before and have decided to hold off on the details until we address the charm/enslave system. At that point I'd like to add a Summoner Class, from there hirelings can be added.
