Hall of Hexes
This is a part of the castle that nearly everyone avoids, for as soon as one steps into the hall, they are hexed with what seems random hexes. There are legends about what lie at the end, but none have made it there, and some have died trying to reach the end. There are wards so ghosts cannot enter the hall at all. Most historians agree that at the end of the hall lies a treasure the four founders found that was decided too powerful for anyone to possess, and created an impenetrable prison for it to be encased in.
