Her name is Alavesa Oril, she was born 25 years before the events of Alduin's return. She hails from Cheydinhal in Cyrodiil, although she is mainly dunmer in blood she has a fraction of human blood. Her great-grand mother bore the same name and was a guard of Cheydinhal during the Oblivion Crisis. Because of what her ancestor did, her family were made into nobility and are of the most important families in Cheydinhal. Her father served in the Great War as a Spell-sword, he was wounded in battle but was saved by a priestess of Mara, Alavesa's mother. They fell in love and five years later Alavesa was born.
Alavesa was a only child and had the full attention of her parents, when she was old enough she was taught how to use a sword and how to improve her magical skills. The other families frowned upon this, as usually a noble child would be taught how to act around visitors or when in the company of an important figure, but Alavesa's father feared that the Empire and Dominion would clash again. Their daughter wasn't expected to fight but to be able to protect herself. After her father died, Alavesa cared for her mother until she too died a few months back. So Alavesa has decided to leave Cheydinhal, something calls her forth towards Skyrim where her fate awaits her.
That's all so far, I'll add more later. Comments are welcome, although there isn't much to comment on.
