The four cities have State Banks, safe depositories for citizens to stash their hard earned gold. Gold deposited into the bank is held, at first, in the bank vault - an inaccessible location, impenetrable even by the finest Thieves. Money can be taken from the bank vault and placed into the treasury using the BANK WITHDRAW command, followed by the amount of gold to take out. Money can, likewise, be moved from the treasury into the bank vault using the BANK DEPOSIT command, followed by the amount of gold to add to the vault. Withdrawals from a city's bank requires sufficient funds in the bank vault, so often large withdrawals have to be arranged with the Barony as the vaults tend to be left with only a minimal compliment of gold. City Barons can type BANK DEBT to review a comprehensive list of debts owed players by the city bank - often a city treasury is based solely on debts to its depositors. Since the city banks are controlled, ultimately, by the Barons of the city, it is possible to change bank accounts very easily. A financial leader need only type BANK ACCOUNT, followed by an account holder, followed by an amount, and their account will be instantly changed to reflect this new amount. There is a great deal of scope for crooked management of the banks, since it is easy to filter away money through the banks - all account changes are logged for safety, and can be reviewed by the other Barons for a month after they have been made.
