Limited Inventory
If you don’t have pockets or other equipped storage spaces you may only hold a couple of items in your hands, within reason, and maybe balance a book on your head.
In fantasies we covet our dimensional pockets. Everyone has a backpack that can somehow hold fifty torches and some random thousand potions of various flavors.
In Vaia, dimensional storage is accomplished with Portal or Gate Magic and having an actual place to store the items. The magic comes later. At first we have Limited Inventory.
