Note:
> Some items disappear when delivering the mission, so if you want to keep the item, it's good to have a char just for that, so you're always on the mission.
> If you have lost an item, you can buy it again with NPC Gnomux.
> One of the most interesting items is the loadstone, which when carried during the mission gains a blue glow, making it a great item to help with decorations.
