Prologue
He had captured the weakest member of the pack. The dark, ancient man standing in front of the tortured blonde was smirking at the horrible dream he had given the boy. Now all he had to do was wait for his beloved best friend to come to his rescue and his revenge would finally be sought.
"Lovely place you have here Ardyn Lucis Caelum."
Ardyn raised his eyebrow as he turned to face the strange man in front of him.
"Who exactly are you? I have not seen you before. Any intruders are usually disposed of immediately. More importantly, how do you know my proper name?"
"I am of no consequence, but you may call me 'The Pharaoh.' I have come her using this simple device on my wrist." This 'Pharaoh' held out his arm and showed him a strange instrument that Ardyn had never seen before. "As of how I know you are a Lucis, I have come from another world. A world that has created a video game where you are the main protagonist. I know all about you Chancellor. I want to help you. Revenge by ending the entire line of Lucis including you is not the answer, is it? Why don't you choose another way? A way so that the line can die but then be reborn after your death?"
"How do you exactly plan on that to happen?" Ardyn inquired. He at first wanted to kill this intruder, but now he was curious. What did he mean by that? There was no way that he nor Noctis could have a child before their final battle.
"Easy, I have advanced technology. I can do things that no one has ever dreamed of. For example, turning simple DNA taken from various sources and created entirely new beings and have them survive. Why not use DNA from that boy and mix it with your own? Once that child has been created they can stay in a tube similar to the one he was born in. That child can grow and thrive for years until after the death of Noctis and yourself. Then this child can awaken and rule as a new Lucis Caelum. A brand-new start for a new Eos starting with your own child. How does that sound?" The stranger leaned against the wall with a smirk.
Ardyn thought this over carefully. He would have to keep this experimental child far from Noctis' friends so they would not release them before their time. More than that, maybe he could also use the DNA of the others to create 'friends' and protectors for his child. He would not mix Noctis' bloodline with anything because he wanted this all to be about himself. His child. Something he had not known for millennia.
"Alright, we have an accord. Now, tell me how to do this…" The dark Lucis seethed as the Pharaoh laughed. This would be the perfect thing to change the story. The Pharaoh just had to make sure Ignis, Gladiolus, and Prompto found the child within the next ten years. Then his secret agenda would be complete. The world of Eos would be no more.
