Vigroy can be found west of the bank in Shilo Village. His location should be marked with a File:Transportation icon.png on the map.
He runs one end of the Shilo Village cart system that transports players between Brimhaven and Shilo Village for anywhere between 10 and 200 coins, depending on the amount of coins the player is carrying. However, if a player uses the right-click option, Transport, then they will only have to pay 10 coins, no matter how much money they have in their inventory.
The Shilo Village cart system can only be accessed after completion of the Shilo Village quest.
