There are two known elves that have been or are the Principal of Foxfire, the only noble school in the elvin world. To become a principal, the Elf must be in nobility, and they have to have presumably been a Mentor previous to becoming a principal. The principal's office is on the top floor of the large pyramid. For a principal's inauguration, they must turn the Key to Foxfire. Foxfire Principals are addressed as "Magnate" for males and "Dame" for females.
The Inauguration Oath:
Do you swear to put the safety and success of your prodigies above all else — even your own life?
