Followers are a broad class of NPCs that follow the player in a variety of situations. Pets are the most common type of follower, but other types of follower NPCs use the same underlying system. Much like pets, these non-pet followers have a corresponding item that will spawn the follower NPC when dropped from the player's Inventory.
The item forms of these followers are generally not obtainable through normal gameplay, and exist within the game code as a failsafe measure in case the follower behaviour is interrupted somehow.
