Bankers are the Bank NPCs. Every town and city has a banker (at the moment). Bankers are tied to the city they are located in. You cannot place an item with a banker in one town and then collect that item when you speak with a banker in another town. However, all bankers in the same town are connected to each other. Bankers have 50 spots of storage. Bankers are easy to tell apart from vendors due to there fat stomach.
