[Harry Potter] Everyday Life at Hogwarts

This author is a bit toxic, so be prepared before diving in. A story about the parents' generation. I figured I might as well write all the pairings in one go, so I'm not keeping to a timeline. The main pairing is Professor-Godfather SSSB, and there are quite a few other pairings. If you want a more useful summary: Sirius spent some time accompanying the young Professor in his Animagus form after an accident.
