Aeon is an antique store that is owned and operated by Irving Onegin. This is the same antique store that Ashley Threet and Emily Niner buy Ethan's initial birthday present. Aeon was built on top of the same spot where Ethan and his friends had their secret hideout. As a result, Ethan has to go into the back of the store during Chapter 3 when he tries to save Ben Fourier. The store becomes a vacant lot when Irving travels to the past in Chapter 5.
