The Marauders Map was written by Moony, Wormtail, Padfoot, and Prongs.
James “Prongs” Potter - Stag
Sirius “Padfoot” Black - Black Dog
Peter “Wormtail” Pettigrew - Mouse
Remus “Moony” Lupin
They were all friends at school. Remus was bitten by a werewolf and a kid. The Whomping Willow was planted and the Shrieking Shack built because Dumbledore wanted Remus to be able to come to school. He would be taken to the shack during the full moon to be safely kept away from the rest of the school. The other three found out and spent years learning to be Animagi so they could spend that time with him. James and Serious were large enough they could keep him in line as a werewolf. Harry’s Patronus is a stag because that is what his father was.
The Potter’s went into hiding and they did a spell to help them hide. It was going to be Serious that keep the secret but at the last minute Peter convinced Serious to have them use him. He told Voldemort, which allowed him to find the Potters. Everyone though it was Serious that had the secret and gave it to Voldemort. Serious confronted Peter and the rest as they say is history.
Same rights, just racism.
