I don't think its a matter of need, but what would you like to play.<br/><br/>That being said, I can see some difficulties with your concept. Unless it's changed drastically in 2nd ed (and I don't believe it has), it is against the law to teach a fate witch to read or to educate them anymore than to manage household chores and handicrafts. I wouldn't go so far as to call them property, but they are very much closeted and controlled by fathers and then husbands.<br/><br/>In addition, in order to use the Sorte power, you need that background, which you won't get from either Doctor or Engineer.<br/><br/>If you wanted to refine this idea, I would suggest Sorte as the first Background and then one or other of Doctor or Engineer as the second, to represent what she has been able to learn after escaping from Vodacce. You might also want to look into Sophia's Daughters as a secret society. Running away from her husband would be very hard ... getting help to get away is a different matter.
