Answer

"I would have revealed myself to you if Yuren hadn't done it for me. But only later, when I have finally accomplished what I promised myself I would accomplish for my best friend."

Darian finally turned to his father.

"You promise me you're telling me the truth."

"Yes, I promise."

Darian walked back to Zion and hugged him.

"You have no idea, my love, what it has been like for me to know that I have a child, that I missed the first years of his life, that I will never know them, that someone other than me was your father."

"Kreiz is not my father." Darian refuted, imperious and unwavering. "I love him, at least in the way I love all those who are...strangers to me? But he's not you. He or anyone else will never be. No one will ever take your place in my heart. And, the time has come for me to finally give up his name for yours, my rightful one."

Zion tightened his embrace around his beloved son.
