The entrance hall is, quite possibly, the most spectacular room in the academy. Its high-arched ceiling is normally the first thing most people notice upon entering. Not only is it extraordinarily high, but it is also decorated with four enormous murals, each a representation of one of the four Cauldwell houses. A large display is settled in the center of the hall, where various maps, pictures, and other information about the school can be found. To the side of the display is a large notice board, where various announcements, reminders, and advertisements are posted by both staff and students alike. Various statues and paintings decorate the walls of this room, which add to the overall grand and exquisite style of the hall.

Aside from dining purposes, the owl post is also delivered to the Dining Hall during breakfast hours. Other than that, however, not much happens in this room. It is, nevertheless, one of the many marvelous rooms in the castle, and seems to be much larger inside than out. The floors are of ivory colored marble, and the walls are decorated with innumerous portraits and statues. The hall is furnished with eight long tables; one is for the teachers, which is situated along the back wall, overlooking the others which are allocated to each of the four houses. These four tables have been lengthened to host some of the many transfer students living at the school. The other three tables -- two parallel to the four house tables, one perpendicular and at the front -- have been placed for extra seating for the rest of the transfers. All of the tables are garnished with white table cloths and have wooden bench seating. In addition, the tableware is also magnificent: white china with blue emblems in the center, and glass goblets designed to look like crystal.

The ballroom was once a common place for friends to gather and socialize, but now it's being used to house well over a hundred transfer students. On one side there are seven tents -- two belonging to Cauldwell's Quodpot team, two to Beaumont's, two to Midlands', and one a donation -- that can hold up to fifteen people each. The rest of the dance floor has approximately thirty cots scattered across it in groups, all of which are being used to sleep in. Ten more cots can be found on the balcony level, with the tables moved aside.

Although smaller than a classroom, the choir room is still nonetheless functional. The wooden risers, which take up an entire side of the room, are the first visible thing upon entering. To the side of the door you'll find a large piano, often moved to the middle of the room for choral practice, accompanied by a small table supporting a record player. Inside the oversized closet you can find a wide variety of instruments, including the few instruments students decide to store there. Although the room is only used for choir practice in the afternoons, it is not unusual to hear the soft sound of music playing from behind its door. Whether it be early in the morning, between classes, or right before practice, there is often someone inside taking advantage of the music-induced space.

The library is quaint and cozy, with cathedral styled arched ceilings, brilliant wooden flooring and wainscoted walls, the top half painted lightly with white and the bottom half paneled with wood. The tables come with comfortable wooden chairs upholstered with dark blue leather seat coverings and small oil lamps in the center, which are charmed to glow brighter than usual. The forbidden section of the library is in a separate room towards the back. The librarian appears to be almost like a guard when she sits at her desk, which is situated in front of the door leading to it. All of the stacks are clearly labeled and there is a reading area nearby that provides plush chairs and couches for the students.

The various hallways within Cauldwell aren't very decorated, save for the occasional paintings or statues that can be found here and there. The walls are wainscoted, the upper half painted in a soft white color and the lower half paneled with mahogany. Some of the more open areas have comfortable wooden benches, which are almost always used between classes.

Although they're convenient to have, the atriums do not have much purpose. They are most often used as areas to socialize between classes, but on occassion they're used as common meeting places between friends (or enemies). There are two atriums: the lower atrium and the third floor atrium. The lower atrium is used much more often than the other, seeing as most of the classes are held on that floor, but the third floor atrium has had its fair share of uses, too. Both are furnished with numerous amounts of plants, benches, and chairs, and there is a large fountain in the center of each.

Teachers can easily achieve peace in their lounge, as it is found on the third floor, far from all the chaos of the school. It is complete with ample amount of furniture to kick back in and avoid the hectic world that is the classes. This is where most of the socializing between the teachers occurs, and it is also where most staff meetings are held.

What the trophy room lacks in width, it makes it up in length. It's actually a rather long room, spanning an entire corner of the second floor hallway. It's walls are aligned with shelves and showcases, exhibiting the many awards and trophies that Cauldwell has won in the past. The floors are fashioned from a hearty brown wood, which matches the paneling on the walls. There are ten cots in this room: five on one side, and five on the other.

The Owlery is quite large; however, that is not alarming considering the amount of owls it needs to accommodate. The school owls come in every breed and are available to any student without their own. Towards the back, there are numerous shelves fastened to the walls that provide an assortment of owl treats that can be used to coax a stubborn owl to leave its perch.
