I was thinking more like the middle age fiefdom system. Or like in A Song of Ice and Fire. Sometimes the Lord or Lady of a fief needs to leave, and they either appoint someone to be the steward and take care of the fief's affairs, or there's already a hierarchy that if someone is away, there's always a next in line who runs the day to day affairs.
I don't know how easy this is to do, but if it's not too difficult, I'd love to see it implemented.
