wait, yo there’s an entire mage magic system in this au? Might I ask for more details?
The short answer is that is a soft magic system, with no hard rules, it's just fun with the characters.
The long answer on the other hand...
I had a similar ask before, but since then some things changed, so I guess I try to explain it as best as I can.
So! This is a magical-fantasy-medieval AU, I was loosely inspired by arthurameslove 's fic This Lonely Knight, but since then I made my own version of a similar premise.
The magic system is based on the original fears, the avatars are people who are affected by their magic, in one way or another. The more close to the fear the person is, the more magical effect it has.
The most known magic users are witches. They go to school to study, and from there, they can go and become advisors in small kingdoms where they can get gifted titles like Lady and Lord, but they don't get actual lands or servants.
Jon is not an advisor, but Elias' protégé and he can afford to employ Martin, who is a Knight, and previously worked for Lord Lucas. Elias is the advisor of King Magnus.
The kingdoms are based around the Fears, with most avatars being nobility or witches. (I wasn't sure if I wanted to make Simon a noble or a mage, maybe he is not so open about his skills)
The witches are glass cannons- they can be really powerful in some situations but otherwise, kinda weak so is a common thing to have a designated knight bodyguarding them if they leave their palaces.
Martin is 'touched' but can't do magic the way Jon, or other witches.
If a witch finishes school, they are respected and believed that they can control powerful magic (with circles and runes) without it affecting their bodies and minds negatively - not like Jane Prentiss, for example. She was a noblewoman who got- corrupted.
Not every witch goes to serve nobility, there are plenty of small village witches, and Gertrude also tried to leave the palace and become a bog witch kinda deal.
Innisially for this au, I made the 'witch factor' the characters' connection to the eye in canon. I didn't see either Tim or Martin really eye-aligned, so I made them knights instead.
Since then I added Sky Mages for the Vast avatars- I just tought flying and stars and sky really deserve their own coven.
I'm not sure about the other fears names and schools jet. The phrase Seer Mage came from @skell3 's fanfic inspired by my comic, and I loved it so much that I baked it in my au.
Also, the thought that eye-aligned mages are all about seeking truth and other's secrets, while can't really fly or fight mutch was funny to me.
So this is a loosy-goosy system that I'm still working on. I'm also open to suggestions- like with Basira and Daisy- they ended up being witch hunters.
And I changed Michael from a jester to an actual noble/prince
So yeah, I hope this answers your question. Mostly a character-based, case-by-case thingy.
