As each of the students steps onto a glowing disk and speaks their name, the disk flies upwards, spiralling around the room. The speed is not intense though, nor do you feel like you're in danger of falling off, as though some field of force were keeping you on board - and keeping the speed of your passage from ruffling your hair.
As you ascend, you notice ledges every ten feet, ringing the tower.
Each of you has stopped in front of a ledge, five feet deep with an oak door in the center, your name engraved upon it. The door opens simply on the first attempt and you find your rooms. The interior is a ten foot cube with a basic but comfortable looking bed; a single dresser; A closet; and a desk, all designed to your body size.
A moment after you enter, an obviously illusory foot tall image of the Dean appears floating above your desk, greeting you by name before adressing you in your home tongue "Welcome to your freshman room, my apologies if the accomodations seem sparse, but we have a rather large student base, and as such assign these temporary quarters to all freshmen. Once you've been here long enough and proven your capability to continue at this establishment, you will be assigned a full-time, FULL SIZE room which you will be able to decorate to your liking. Until then, consider this a test of 'making due with what you have'." The dean smiles and his image fades.
