Map over Hogwarts School Ground Floor

It's not possible to make an exact map of the other floors because of the fact that things move around in Hogwarts.

Plot:
It has been years since the fall of the Dark Lord Voldemort. The ones involved in the war has long since died or moved on to other parts of the world. However, the wizarding community isn't entirely free from the anti-muggle behaviour of the followers of Voldemort. Several managed to claim innocence, even thought many knew they were lying. Through these surviving Death Eaters has a new rebellion against the Ministry risen, although more subtle than the conflicts with Voldemort, they are mostly unknown.

For now, the anonymus Death Eaters are plaguing Hogwarts School of Witchcraft and Wizardry. They diligently work to prevent any mudblood students from graduating, while singling out purebloods to recruit to their cause. It's up the the students to save themselves.
