The Abyss of Time

After the Giant War, the new lucky number for quests was either 3 or 7. This would come in handy many years later. In 2031 the legacies of The Seven were teenagers. It's time for them to fulfill their destinies and go back in time. While in Tartarus, Percabeth received a curse that would not affect them, but their children and friends children. They would go back in time to 2019, while Harry Potters kids were attending Hogwarts. The only way to go back was to survive one year at the school. Will the magical boundaries of Hogwarts be able to keep the monsters out? Will they make it back? Only way to find out is to read this crisis develops.
