Those scrolls we can craft, it would be very cool if we could write on it, being useful for many things, like making notes, lists, names, even leaving messages for other players in the wall next to the door of their bases/houses.
In Sepemeru could have a place with plaques or a mural where players could put notes about things they want or have, like a Market Place, players trading with players. This would add more to the city life aspect.
