The A '''bank''' is a facility equipped with a high-security vault. A bank's purpose is to securely hold money, valuables, and other objects for a town and its inhabitants. Banks provide banking and storage services for a fee. Banks are operated by local [[Citizen|citizens]] called ''bankers'', which are appointed by the [[mayor]]. The premises are protected by the local [[Town Security]].
Although the bank in each town is independent, bankers maintain their customer database and communicate with one another through the MazeNet computer network, via secure applications. Every time a change occurs on any account, it is logged and updated in real-time. Banks also frequently hire couriers and armed escorts to deliver money and items in storage from one bank to the next; this courier delivery service is how customers may "retrieve" items from any bank, even if they were not deposited there in the first place.
