Characters within the game range from enemies to your own citizens. Vault citizens are known as dwellers and players have taken to calling enemies invaders. Rare and legendary dwellers are found in lunchboxes. Legendary dwellers arrive wearing a legendary outfit and a rare weapon. Rare and Legendary dwellers keep their outfit when entering the vault, rather than immediately switching to a vault suit. Some Legendary dwellers, such as Sarah Lyons, Three Dog and Preston Garvey, can be obtained by completing their respective quests from the Overseer's office.
