Maintenance List is a written note in Dishonored 2.
-Repair the things that got busted up in Anton's room, when he was taken. It's been weeks now.
No, scratch that. Not until I bring him back home. As a show of faith that he will be coming back.
-Unblock the storage door. Looks like something fell on the other side. And I really need to sell the stuff locked up in there to make some coin.
-Pay the port tax and the "look the other way" fees to those Grand Guard bastards, before they wonder who my passenger is this time.
I'll do it when I get the money.
It can be found on the table near the guest quarters in the Dreadful Wale.
