[@Lucius Cypher] & [@Rtron] an I will look over the CS when all three are on, giving you one review. I do see one main issue, which completely alters the CS, and while I'm pointing it out so you can prepare with changes and addition, I would like you to wait on making official edits until we all have looked over the CS together. This way there's not additional work for you. :p  

The CS says age wise needs to be 18 or older, despite the joke part about mind wise. Let me explain the reason why. It's because a way for college to help mages develop their magic is through missions, which are too dangerous for children and forces us IC to place your PC on the sidelines for every single round of missions. These happen often enough that your PC will miss out on interaction chances. Also means your pc will have the knowledge of his magic level, but not the power or practice to back up his magic. None of the other Players are younger than 18 (though Colette appears it) save Lyn and she is about the only exception because she was born at the college and is aging at a rapid rate, like 2-3 years for every month. In the next time skip which happens within another 2-3 months, she will be 21 and her age will slow to a Naga's.  

My suggestion, you can have it where his magic showed at 13, but add about 5 years onto the bio. He could've just recently came to the college and due to his blood appearing at such a young age, not everyone came instantly, he was prevented at coming earlier. Mainly just because he's had the magic, doesn't mean he's developed it and he would still be a novice technically.
