When the gods left earth, so did everything, and everyone else, including the Furies. They were put under my charge to be kept in the Underworld, but they were difficult to control and were always trying to take over my job as torturer. I gave them some freedom in Tartarus to do just that, but only for one person, for one day. That was the deal. They had no purpose, and I gave that back to them. Now? Now they were who knew where.
