The Bank of Pi was a financial institution created by Pi. It was founded on 2E:61 and continued to serve clients for most of the Second Era. Tox and Macca donated materials towards its construction. The bank featured individual vaults that were accessible only by a unique custom key belonging to the person who rented the vault, serving as sort of a larger ender chest. Each vault could be rented for three iron ingots a day or 64 ingots a month, with the option to pay in advance. As the first vault owner, Tox received his rent-free as thanks for helping test the locking mechanism.
