Harry Potter only keeps a few valuable treasures from his time at Hogwarts. Fans of the series know that he has a small number of valued possessions such as the Invisibility cloak, his wand, Firebolt, and of course, the Marauder’s Map.
The map was created by the Marauders (Lupin, Sirius, James, and Peter) as a way to navigate the halls of Hogwarts and to keep Lupin hidden away when he went through his horrific werewolf transformations once a month. The map is an extremely important object in the series. But there are a few things about it that don’t make a whole lot of sense or present some interesting questions.
