Oh, that was too bad. Kurumi was rather hoping that she would have another cookie recipe to add to her cookie recipe notebook.

With a slight frown on her face, Kurumi returned her wand to her holster and returned that to her robe's pocket. "They last as long as it takes for a counter spell to take effect?" Kurumi asked cocking her head to the side. "Charms seem to have certain boundaries set on them and the most powerful of these being the Fidelius Charm whose effects never really wear off. Sure, the information is then leaked when the Secret Keeper divulges the information, but when a Secret-Keeper dies, their secret dies with them, or, to put it another way, the status of their secret will remain as it was at the moment of their death. Everybody in whom they confided will continue to know the hidden information, but nobody else." Then again, this could just have been a special case with Charms, but every charm they had learned also had one to reverse its effects. Would a Severing Charm ever really wear off? Kurumi wasn't really keen on sitting in front of a several block for hours or days to see if it would ever come back together again.
