The Trade Shop NPC divulges information in a stoic deadpan tone and only shows a smirk when talking about how his store acts like a bank as well.[1]
Background
His function is buying items from players (only in card form) in exchange for the Island's currency which is Jenny in card form. He also sells information to players such as card functions and directions to the Island's locations and also functions as a bank, where he takes players' Jenny cards for safekeeping.[1]
