while cleaning, the House-elves find the idea so insulting that Dobby is the only resident elf willing to clean in Gryffindor Tower. In Deathly Hallows, Dumbledore tells Harry: "Of House-elves (...) Voldemort knows and understands nothing. Nothing. That they have a power beyond his own, a power beyond the reach of any magic, is a truth he had never grasped". Kreacher also leads the House-elves of Hogwarts into battle against Voldemort's forces. Harry Potter depiction of race, specifically the slavery of house-elves, has received varied responses. Scholars such as Brycchan Carey have praised the books' abolitionist sentiments, viewing Hermione's Society for the Promotion of Elfish Welfare as a model for younger readers' political engagement.
