House-elves are magical creatures known for their loyalty and service to wizarding families. They possess powerful magic but often choose to use it for household chores, such as cleaning and cooking. House-elves are bound to serve their masters, and they can only be freed if they are given clothes, which they cherish as a symbol of freedom. One of the most famous house-elves is Dobby, who initially served the Malfoy family but later gained his freedom. House-elves have a unique culture and often take great pride in their work, believing that serving their masters is an honor, even if it means sacrificing their own freedom.
