The College

Although referred to simply as 'The College' in reference to both the structure and the academia within, Argos' pride and joy is much more than a simple building. A part of his GRAND LIBRARY, it is the only official wizarding school in Orasrupt due to Argos' determination to not only possess all knowledge but ensure that no one else has access to it unless through his library. Most frequently, it ejects the often insane husks of failed students, but sometimes, Argos' stringent indoctrination and intense lectures bring forth angry, powerful wizards willing to destroy anything he points them at.
Due to the few and far between wizarding schools, any fresh wizards on Orasrupt uninvolved with The College are either from one of the barely surviving planes of the multiverse, or are trained by a personal mentor

Structure

The College is a meritocracy. However, Argos controls 1/7th of the name of YISUN, and is incredibly powerful in that regard, meaning he has cemented himself in his power. Further, he does not believe that he can be beaten.
For each school of magic, there is a department head. Under them, are professors.
