So, finally I have a large amount of free time from the university (I do letters in english. Don't know if this is how english speakers call this course) And now I wish to roleplay a thief. So, here it is:

Joanna Danglair is a young breton girl who left high rock to make her furtune. Daughter of a powerful court wizard back in High Rock named Mirella Delacroix and a Nord called Volundr Eriksson, She left her homeland when she was 17 years old and travelled to Cyrodiil where she tried to be a mage. The Arcane University rejected her because of her taste for Necromancy. A female nord approached her and told about Winterhold and she decided to give it a try. Arriving at the border, she saw a group of nord men scorting someone of importance. She asked them for directions, but unfortunately, the Imperials from Cyrodiil were there to ambush the group. She got hit violently in the head.

So, I did not like it that much, but... People's voice is the Divine's voice!

Seems nice. Whatever works for you/gives your character their basic motivation is fine.
