I think, every Graalian month, there should be a fair where people gather all they can to sell at booths. It would be composed of a street lined with booths that players can rent for the duration of the fair. When you buy a booth, you'd be able to but items that you plan to sell in a "storage bin". Players would be able to see what you have to sell, and they'd buy the items depending on the price you set for them.
It would be kind of like a mass trading session, except it would be more profitible, as players would stock up on items beforehand. If uploaded, a fair would serve as the economic heart of Graal. I could make the levels, but let's build on to this idea
