On 10/27 Eldarian announced the following in a player meeting:
The Bazaar area will be located in the East Commons Tunnel and players will be able to sell even if AFK [bazaar fashion]. Upon implementation, guards will be placed in this area to protect sellers and customers from any potential trains. It is unlikely this enhancement will be available at initial launch, but the AFK bazaar system is one of the higher priority features.
I have asked that a banker be located in this area as well.
