What happened before the Marauders? Specifically within the Black Family. Walburga, Alphard and Cygnus. As well as Orion and Lucretia. These events are for my personal headcanon. An slightly explanation to why these characters are the way they are. The ones we know or we hear about from the original series. This is not particularly a story. Just a chain of events that led these characters to be who they are and do what they do.
