Osirian

Every Chosen One has someone to balance her, just like yin and yang. This person is called Osirion. The Chosen One's Osirion is her complete opposite and protector. Rufus was Sarah's Osirion. The identity of Nina's Osirion remains unknown, but people think it's either Fabian and Eddie. We do know that it is indeed a male since the ghost of Victor Sr. refered to the Osirion as "he."
