Faculty Dorms

All faculty reside in the faculty dorms on campus. Each member has their own little apartment style room. The dorm rooms consist of a bedroom, bathroom, kitchen, living room, and study.
The room numbers are the tower the room is located in (N for north tower, S for south tower, W for west tower, and E for east tower), the number of the floor it is located on, and a letter for the tower and another number for floor. There are twenty-six rooms on each of the twelve floors located in each of the towers. That is a total of 1,248 rooms. The Headmaster's room is located at N12A721 (north tower, twelth floor, room A, room 721).
The towers are connected by a series of corridors on each floor, except the first and twelth floors. There is a lush green garden in the middle of the towers with benches and a small pond. The laundry facilities are located in the basement of each tower. And have no fear each tower has two elevator along with a flight of stairs.
