Fics like Gellert Grindelwald and the Gryffindor Horde

Gellert Grindelwald was the (former) Dark Lord of the early 20th Century. Now he is locked up in a prison he built. As a war rages on in Britain, Grindelwald escapes from Nurmengard. Harry Potter is an orphaned child. Neville Longbottom might as well be. Two of Albus Dumbledore's worst nightmares clash in very bizarre ways. -- or: Grindelwald adopts Harry and Neville on a whim and gets unrealistically overprotective.
