All magician clans uphold one rule when establishing the legitimacy of their members: if one has the aptitude of a magician, they are considered legitimate; without the aptitude, they are illegitimate!
No matter who your maternal family is, magicians rely on their innate talents. Some people, no matter how distinguished their birth, simply can't make it, and that's that. It can only be said that those with a good maternal lineage initially enjoy better educational resources. But once they pass ten years of age and their talents are confirmed, the clan will reallocate resources according to those talents.
And for a family within the clan to secure more resources, they must put forward the child with the best magical aptitude. Over time, magician families have come to prioritize talent above all else.
