If a Magix is killed, it's human looses all of their magical abilities.

Evangelina Nott comes from a long line of success. Both her parents were squibs from separate houses of the sacred 28, social outcasts that were forced to make their own way. Her father came into money on his own, and her mother was able to raise her little Evie to be a proper lady. On her tenth birthday, the family expects another quiet evening, but the squib gene seems to skip a generation. Evangelina finds herself in the company of her own Magix, and the next year holds a letter to Hogwarts firmly in one hand.

Her wealth and her status draws the attention of a certain Orion Black, who happens to have a son in the young girl's year. Despite the bad blood that comes from the family, the match wouldn't hurt. His standing would increase, as would his own wealth. Yes, this elegant, serene girl would be fine. This perfect lady would be a wonderful match for his Regulus.
