She is a mix between warrior and mage pretty much. (One sword, backed up by destruction (especially lightning) and conjuration magic wearing heavy armor)

She has a bit of ''mysterious'' appearance, a pale skin, black hair and light gray eyes.
I am not too sure about her personality, though she will probably be very shy but also very wise.
I haven't decided yet if I want her to be a werewolf, though I do think it fits well.

Also, she is a nord.

So I am thinking about something germanic. What about Raganhildis? I believe it means Advice, Wise and Battle in old germanic.

Never mind, I think Raganhildis should do well.

Ingrid or Ida

This, nice real nordic names No offense, but Raganhildis sounds like two names to me, Ragan which sounds like a male name, and Hildis a female one, put together. Imagining I had a friend named Raganhildis, she would get a nickname SO fast.

Yes, but it also sounds very ancient, which is what I want.
What about Valdis?
Valr means: ''the dead and the slain''
And dis means: Goddes, Woman

Combined would be Valdis, sounds good?
