Guardian - Pope
A legal guardian is a person who has been appointed by a court or otherwise has the legal authority (and the corresponding duty) to make decisions relevant to the personal and property interests of another person who is deemed incompetent, called a ward.
Guard(ians) would have control over the bank as part of some legal instrument/agreement
A ward would be the person performing the guarding of the property at the behest of the Guardian.
What loyalty would be higher than that of truth?
