Unlikely

Frea, is a young nord who has grown up nearly her entire life in Valenwood along side of her scholar parents, and her adoptive sister, Viola, a bosmer and nord mix. She has always been happy, despite the problems with the thalmor, and shielding her sister from their threats. However after Viola leaves because threat is to much for her to handle as she gets older, and Frea's mother dies leaving her father to become more and more distant to the world, there is nothing left for her in Valenwood, so she travels north back to her homeland of skyrim that she left when she was ten years old. She has never killed a man, and barely knows how to fight. She has learned what she could of the bow from Viola, and is rather talented with swords, from practicing on dummies, and hunting.

Frea is not a dragonborn, that is her sister's job. If you read viola's story "back to home" they are both intertwined. Rate and comment if you want :)
