[@Darkraven]Very well made character. You might need to de-power her a tiny portion, but not by much and I'll let you know if I think changes should be made for the future. Atm though I just have questions. I assume the Knights she was with were a holy order, and if so, would they not have magical items to detect her? 
Then again, I take belief as a large part of my lore, so perhaps since she had amnesia, at that time she WASN'T considered demonic, even despite her nature within. Plus, many of the Knights might be enamored with her and would not heed such warnings anyhow. But still, the question remains. 

Also, is her daughter full human? 
 
Make her race, Human (Andredian), if that is where she considers herself from.
