The Marauder's Map is a unique magical artifact that was once created by the "Marauders," who studied at Hogwarts. It depicts Hogwarts and its surroundings, and it can track the location of any wizard, even if they are wearing an invisibility cloak.

As the story goes, a rather impressive and complex magic was used in the creation of this map. Thanks to it, the one who opens the map can trace the steps of anyone who is in Hogwarts.
At first glance, it may seem like just a piece of blank parchment.

By saying the secret phrase: "I solemnly swear that I am up to no good," all of Hogwarts will be revealed to you, as if it were in the palm of your hand.
However, one must be careful with it: if you do not say the password and touch the map with a wand, it may not only play tricks on the one who opens it, but it can even insult...
