Sorcery using Trader(G.T.C)

Who is this? How did I end up with this guy?
What you are seeing is one of the specialities of the G.T.C, which they use many sorcery to fill the Merchants needs. They are summoned after talking to one of the traders situated in the Branch houses in each islands, simply by asking for an trader, in which case a wizard will be summoned by the greed of money, and they will begin to trade the specified Barrel, in exchange of gold which will be automatically be transfered to the trader situated in the store, afterwards the wizards would recieve their money and disappear.

In recent studies, over 15 wizards were documented to be on stand-by for any summonings.
