House-elf

A house elf is a magical creaure in the Harry Potter realm. THey serve wizards, and must do everything that their master commands. A house elf may not be set free unless they are given clothes by their master. Usually they wear dirty pillowcases or something of the sort. As demonstrated by Dobby, a house elf that Harry met in Chamber of Secrets, they are very powerful when free. Most house elves, however, wish to remain enslaved and enjoy it very much.
