Magical abilities

The ability to alter the reality through Magic is inherited, and the methods to use it effectively can be either developed by each wizard, or learn from their community.
Without any well thought rituals and spells, most wizards wouldn't be able to use magic, and for those who are close enough to magic to use it without those channels the results would be unpredictable.

Affected Groups

Long time ago, there were many wizards, and very powerful too. It's thought that they would gather in societies or transmit their knowledge from parents to children, but it's possible that some of them had preferred to develop their own ways to interact with magic.
Currently, all wizards live in A distant town, as a single community which they call The Two Families. They all use the same magic methods, and they have to respect several restrictions.
