When Lord Voldemort began his reign of terror he also began to collect horcruxes. Seers made predictions, some bogus and others true. One being that the Dark Lord would mark a child as his equal. We all know this happened. The Boy Who Lived. Harry James Potter, he went on in life facing many dangers. In his seventh year of Hogwarts, he instead opted to stay out of school and find the items in question. He found them, and when he did he managed to destroy them. In the final battle, Voldemort was destroyed.
Twenty-one years later, Harry Potter is happily married and his scar hasn't plagued him for all these long years. He has two sons and a daughter, a god son, a niece and a nephew. He's got a family now. He hears about all these amazing, sometime marauder-esque activities that his children preform at school. He's happy, finally able to relax.
What if there were three threats coming upon the wizarding world. One that seems to familiar and two that work together to foil all plans against them. Everything that happens seems to be playing into one side's or the other's.
Secrets are being spilt and no one is sure who to trust now. Dark corners of the wizarding world, that adults have tried to hide . They were once covered with the cobwebs of neglect and now, they seem to be speaking to anyone who is willing to listen. Crime is on the rise in Wizarding World and everything that they have worked so hard for is slowly being torn apart by a serpent from the depths of the darkness and wolves from the center of the fray.
