A central floor to the school, the third-floor corridor is a relatively easy to navigate and contains your basic necessities. On this level of the school, the Charms classroom and the Hospital Wing can be found. Additionally, you will find the pristine Armour Gallery, the Trophy Room, and a passageway to the more popular places on the grounds. But that doesn't mean there aren't a few peculiarities to be found in this part of the castle.

Beyond coming across portraits of Basil Fronsac, Damara Dodderidge, and Merwyn the Malicious, you will find that there are many rooms to explore. The Ghoul Studies classroom resides on this floor, as well as a room where spare furniture is stored (perfect for making indoor forts!) and another containing maps of Great Britain and Ireland. Though perhaps the room you find most curious is a storeroom containing a large golden harp that plays on its own accord and a trapdoor -- it can't be said for certain where that leads, for it looks like a rather long drop. Probably not the best idea to find out.
