How to Access the Auction House
You can access the auction house wherever you are. You don’t need to find a specific NPC. To open the auction house just press the P button. In there you can browse the goods and also list goods for sale that you have in your inventory. If you buy things from the auction house you need to collect it in the in-game mail. This is not the same mail as the Marketplace mail, it’s the mail system you access when interacting with the owl sitting on a sphere next to the warehouse manager NPC.
