but it seems formidable. Along with the ability to Apparate anywhere at any time, Dobby, Winky, Hokey, and Kreacher all demonstrate that they can overpower wizards when necessary: In Chamber of Secrets, Dobby forcefully repels Lucius Malfoy while protecting Harry; whereas in Harry Potter and the Goblet of Fire, when Barty Crouch Jr. is unmasked and confesses to what happened on the night of the Quiddich World Championship, he says: "Winky used her own brand of magic to bind me to her", and in Deathly Hallows, Harry tasks Kreacher with capturing Mundungus Fletcher and bringing him to 12 Grimmauld Place, a task that he accomplishes within a few days;–– even though, as Kreacher puts it, "He has many hidey-holes and accomplices". Moreover, although House-elves are not allowed to carry wands, they do not appear to need them, being capable of magical feats without them. In Goblet of Fire, it is said that a House-elf who has been freed is expected to find a new family to serve. There is an Office of House-Elf Relocation at the Ministry of Magic to facilitate this. House-elves are unendingly loyal to their masters; so much so that Dobby, who served the Malfoy family, attempts to punish himself each time he utters a negative remark about them (even after his freedom) until the final book, in which he defies Bellatrix Lestrange. According to Kreacher, "a House-elf's highest law is his master's bidding"; however, while House-elves must obey their masters without question, they have been known to find loopholes in orders that allow for unintended interpretations to protect themselves or their friends. Because of their docile, obedient natures, some families abuse their house-elves; Dark wizard families in particular seem to make a habit thereof, as when the Malfoys forced Dobby to torture himself, or when the Black family customarily decapitated their house-elves as they became enfeebled by age. Nonetheless, most house-elves are horrified by freedom even from the most cruel masters. Dobby, the first introduced, is the sole exception; but this extends chiefly to voluntary service, paid labour, and choice of his own employment and costume. During her time at Hogwarts, Hermione establishes S.P.E.W. (the 'Society for the Promotion of Elfish Welfare') to champion House-elves' rights; but gains little interest from her classmates or the House-elves themselves. After Hermione begins leaving elf-sized clothes around the Gryffindor common room, intending for Hogwarts' House-elves to inadvertently free themselves
