Tristanian Academy of Magic

The Tristain Academy of Magic is an institute in Tristain that teaches students from aristocratic families in the arts of magic and the study of main elements such as earth, air, fire, water and the extremely rare element Void. The academy has three grades, first years have brown cloaks, second years have blue cloaks, and third years have black cloaks. The academy's current administartor and principal is Osmond.

Magical symbol
The image above is the basic symbol for magic. The students have a gold or brass pendent for holding the cape of their uniforms on. Colbert stated that void was apex of the pentagon. Its reasonable to assume fire and air would be the left and right arms, earth and water would likely be the lower arms, and the top would be void.

Building
The Tristain Academy of Magic was built like the pentagon symbol. Each tower has a different color roof. Can't tell if they are different shapes. It looks like each tower is used for teaching each one of the five magic skills. I would guest the Tristain Academy was build some time after Founder Brimir and Gandalfr. Since there have been no void mages for a very long time the one hallway to the left tower was not put in from the center main tower. That tower is not used for teaching since there is no void user or teachers. Maybe used for storage or a backup class room.

Magic and Willpower
The number of elements that a mage uses can be increased, and his/her class changes accordingly. A mage who can use only one element is a Dot. Ability to use two elements – A line. Being able to use three element - A Triangle. Being able to use four element - A square. Spells are also applied to the class. The spells from three elements are called 'Triangle spells'. Each time the spell class rises, the consumption of willpower doubles. Two mages can combine spells into even a higher level spell force, as demonstarted by Wales and his lover.
