Harry Potter: The New-Blood Project NBP

In the times of Grindelwald, a group of muggleborns started a project to eventually have a pure-blood family to represent them. They reached their goal in 1979 when Onyx Grey was born, first of his name and house. Will he accept the burden or will he refuse to play the role generations hoped he'd take?

Anything you recognize is probably not mine btw. J.K. Rowling came up with most of the setting. General fanon helps out to complete it.
I don't own the picture either. I like it though!
