For example, when Hermione Granger, a very clever student at Hogwarts School of Witchcraft and Wizardry, is enraged over the wizarding world's treatment of house-elves, she creates an organization to help put an end to this injustice. She calls her organization The Society for the Promotion of Elfish Welfare, or SPEW.
