The creation of a Bank Vault has unlocked the Banker profession.
Banker: You have special access to the bank vault in town. You may store 200 ducats or one item (of any size) completely out of game (in a specified area) per rank in this profession. You may access this storage one time, per game, per rank.
Perhaps I am looking in the wrong spot, but I do not see where I can add that to my character.
I can’t add it - Eben will be adding it to the database soon. Patience.

My sincerest apologies. Look again. 
If two bankers are collaborating, can they share one storage, with a maximum size of the smaller of the two bankers maximums, or does each banker have to maintain their own space?
They cannot share.
Alright, thanks.
