Beautiful Creatures: Return of Seraphine

My mother tells me stories of how she defeated the all powerful Seraphine all the time. I have had dreams about that monster ever since I turned four. Whispering to me about making us a family again. I don't know what she's talking about and I don't care either. I tell my mom about them and she says their just dreams. It was on her 16th birthday where she claimed the dark and the light. Shes says it possible for me to do the same because I have a strong will. She's now the most powerful light and dark Castor. Being her son I wonder what that makes me.
