@SaggoGuilty : likely the villagers who are partly guilty of her being ostracized and mistreated. There is not way her parents treatment of her was not noticed, and they let it happen.
@phoenixir : A stronger connection to their instincts? Either that or the much lesser levels of pride, greed and arrogance. Seriously her "parents" had no reason or need to abandon her, they just decided they did not want her because she was "not as good" as her sister, and an opportunity to abandon her came up.
