Osirian

Every Chosen One has someone to balance he or she, just like yin and yang. This person is called Osirian. The Chosen One 's Osirian is her complete opposite (personality, gender, etc.) and protector. Rufus Zeno was Sarah Frobisher-Smythe's Osirian. The identity of Nina Martin's Osirian is Eddie Miller. Nina and Eddie may one day become more than friends or may become very close but still remian platonic. The Osirian has powers like The Chosen One, stated by Senkhara who said The Chosen One could be replaced, but those are still unknown. The Osirian is based off the Egyptain god Osiris.

It is not destined for the Osirian and The Chosen One to be romantically linked but it may happen due to the fact that the Osirian is very protective of The Chosen One. The Osirian(Eddie) destroys Senkhara (in Nina's body).

Fabian Rutter
Senkhara sought to find the Osirian. She thought it would had been Fabian because he always protected Nina. She also thought it was Fabian because when she was giving Eddie her hand, Fabian awoke and Senkhara called him a "natural protector". It was revealed in the Season 2 finale that it was not Fabian and was instead Eddie Miller.

Eddie Miller
Eddie was revealed to be the Osirian in the finale. Senkhara visited both Fabian and Eddie in their dreams and it was revealed Eddie could see her. Senkhara planned to curse Eddie as well because he may have been the Osirian. Eddie knew Nina needed help because she was in trouble so he rushed to the library to save her.

Eddie got to the library and the Frobisher-Smythe gem was glowing in his hand. Nina walked towards him and said "Your my Osirian." He nodded and then asked her if she was sure of what she was doing. She said yes and then took the gem from Eddie's hand. When she was walking towards the portal of the After Life, Eddie grabbed Senkhara's crown and banished her out of Nina's body in order to save Nina's life. Eddie is now going to protect Nina at all costs.
