Kurumi, still caught up on the whole crup incident from last term, listened as other listed off famous instances of the spell in magical history. She too, remembered one such instance involving the Boy Who Lived and a certain potions' book, but her focus just couldn't be wavered from the poor defenseless cruppy. "The former professor of Care of Magical Creatures, Professor Saylen, used the spell to remove the forked tail from a cruppy last term. Owners of crups are required to use the spell, which is painless, so as to hide the presence of the creature from non-magical people." Barbaric really.
