[@NecroKnight] Right now the only hard and fast limits would be if they makes sense in the context of the setting and if it would make you far too powerful in comparison to other PCs. I can't define clear criteria and would have to judge when I see it. 

Keep in mind magic is being rediscovered but it's not common like in Skyrim or D&D. It's mysterious, it's powerful, and most people find it pretty scary.  

So it's certainly possible that a noble might have learned magic but you'd have to come up with compelling backstory for that in addition to how they learned magic while also training at arms and becoming a Lady Knight in a society that is still heavily patriarchal. Everything we see of magic in the universe implies that it takes a long time to learn and master to a useful degree. It's not like the Elder Scrolls where a random schmuck can learn to fire an ice bolt or fireball easily. So basically it depends on how you write it and portray it. We have lots of women warriors in the RP but almost no overtly magical ones so I'll have to see what you come up with.
