Fixed device, or fixed object is a not widely used term that applies to any object that cannot be picked up or moved (is fixed in place) in the game world, but can be interacted with in some way (buys from your character, works like a container, exchanges items, opens or closes, gives a quest, can be read, repairs your items, sells to a character, etc.). The most commonly used object of this type is the mailbox.

Fixed devices are distinguished from spawned objects in that they never appear based on some trigger or disappear after use. They are always present in the game world.
