House-elves are magical creatures known for their loyalty and service to wizarding families. They possess unique powers, such as the ability to apparate within and out of places where wizards cannot. House-elves often wear a simple piece of clothing, like a pillowcase, which symbolizes their freedom. They are usually bound to serve a specific household, performing tasks like cooking, cleaning, and taking care of the home. One of the most famous house-elves is Dobby, who initially served the Malfoy family. Dobby's story highlights the struggle for freedom and equality among magical beings. Many house-elves, however, are content with their roles and believe that serving wizards is their purpose.
