Neville Longbottom in Marauders Era

Neville opens his eyes and finds himself in 1975 as 16-year-old Magnus Neville Longbottom, his second uncle. In a world similar to his own but with many things different. His father was now his cousin who was dating his mother Alice. And Neville was now the heir and next Lord Longbottom who had a marriage contract with Bellatrix Black who in this world was the same age as him.
