When ex-lovers clash

Theo's POV: 

I shook off the guilty feeling from my heart and glared at Lilin. I was not even mad at her anymore. All my anger was now directed towards Oberon. He shrewdly played the game by hitting me where it would hurt me the most! 

"And that is why we both have to join hands to defeat Oberon," Lilin said. 

Still, I wasn't able to figure out what her true motive was. I don't think that she just wants to destroy Oberon alone. Her quest must be more than that. 

"Okay, Lilin. Now tell me how exactly Oberon betrayed your mother?" 

I asked her that question just to know if Oberon is really her target or not. 

"Oberon made two promises to my mother. One was that he would kill the Dawn—but instead, he sacrificed her and strengthened the force of light. And the other promise was that he would offer ten Faes every year to join the Shadow forces—which he never did."
