Her origin was a question now ever since they discovered the complicated fate between the lycan and how he recognized the first Serafim's life essence inside of Iris, which they strongly believed that was the reason why Lu chose Cane to be his new vessel after Haco.
Her father was alpha Gerald and everyone knew about his bloodline, since he was the alpha by birth, but then there were not many people had knowledge about her mother and as long as they know alpha Gerald took fancy of her, impregnated her and then she died because of illness when Iris was one year old.
People didn't pay enough attention to her mother or her origin because even though she was a luna, she was not alpha Gerald's destined mate, neither her personality made her stood out among the other women alpha Gerald had at that time.
Just like Iris, her mother was so timid and didn't speak if it was not necessary.
