Great. I'm currently thinking of a mage with the ability to use some sort of white energy that is harvested from oxygen's particle, which is kind of complicated and a bit fictional scientific. So basically it's everywhere, its source is almost unlimited, but the fact that it is a lot more stamina consuming than other elements balances the power. I'll go to deeper explanation in the CS

Sounds very intriguing, just don't be too overpowered.

There will be a variety of classes to be learned but generally it's going to be more loosely available, like one teacher testing your general abilities and growth similar to a real world homeroom teacher, the rest teach on certain days they choose to lecture or when directly visited by students. Similar to college. The library is an expansive collection of all history and knowledge the Archwizard can collect including hand written journals and tomes explaining specific spells. As aspiring wizards in the rp's world you're looked at with the expectation that you are eager to learn and are trusted to learn with little supervision.

So confront teachers you want to learn from specifically, go try to read what you want to learn, and interact with students and NPCs when you want to.
