Interdimensional Bank
From Jenny Everywhere Wiki
The Interdimensional Bank was an infinitely-large interdimensional bank. It contained a hallway with infinite rows of teller windows on each side. Like the Interdimensional Hotel, the Bank principally employed castaways from lost universes.
Beneath the Bank were physical vaults, which one accessed through trapdoors hidden in the main hall. Jenny Nowhere had a vault at the Bank, which contained a number of artefacts and keepsakes belonging to her various incarnations. (PROSE: Century Smith and the Time Terror)
