Treno Auction House
The Treno Auction House is not so much a side quest. It’s an area in Treno where you can bid on and purchase items at auction, including several rare items that you can trade to various people in town for extra Gil.
The auctioneer will announce four items, which will be put up for auction as soon as you enter the auction house. You can leave the auction house and re-enter to reset the items if you wish to look for something specific.
