If you want to create a gallery to display your prized item collections, head to your Inventory and click on "Item Gallery" at the top of the page. You'll then be taken to a page where you can select your gallery's name, setting, and Gallery Keeper. If you are over the age of 13 you can also add a description of your gallery and customise it with some HTML. Opening a gallery costs 150 NP. Galleries can also be expanded for a small NP fee.
