Yep, meh fantasy settings are a dime a dozen - so they're "make your own and don't ask others".
Good, competitive fantasy settings are far more rare and require a real author (somebody like fr.wikipedia.org/wiki/Agone_%28j ... C3%B4le%29). If made to order for a specific background feature like Hermetic magic, they will at the very least cost a lot of money.
Would somebody - perhaps the one who has already inappropriately volunteered for line editor (Losing Mythic Europe), he will never get it back.
Cheers
