From Time to Time - A Harry Potter AU

When two ex-followers of Voldemort gain access to a powerful device, they decide to turn back the clock and help the Dark Lord to fulfil his destiny of ridding the world of muggles. But changing a smudge of history brought a prestigious pureblood family into the spotlight, and ruining their plans of going to the United States, forcing them to stay in England. But this family might be getting what it deserves, as they hide secrets and choose to forget their true identity. A consequence of staying in Europe is that their children's lives intertwine with those of the Golden Trio and are also forced to go on adventures of their own.
