They are given the faction by who ever, there-for allowing them to use it in anyway needed. Even if the person who controlled them was still using them ,its a waste of time because said person will just be giving there money to people until they can rebuild what they lost and its just a waste of time for that person and for us to wait for him to take his/her turn.
Basicly, its still going to be the same if the person is still in control of the faction and they are giving the money to them from the Kings Purse.
