An Inventory is an object that contains other things. It is used to track items that a Person carries. A different specialized Inventory is used to track what Apparel a Person is wearing. A trunk or bookshelf might use an Inventory to track what is held within or upon it. In a more traditional sort of location-based Twine IF, each location might even use an Inventory to track what items the player can find or has dropped there.
