A/N: This is an idea I had before. I normally detest OCs, but I still want to write her in. Let me hear your feedback on her, so I know to include her in the actual series.

A/N #2: Chronologically, this takes place after the first story.

Disclaimer: Just to be safe, Rick Riordan owns Percy Jackson (the universe where this is happening)

Sydney was still sleeping when she heard a gunshot. She jumped awake, not sure what happened. Nothing happened in her home. But when she went downstairs, she saw blood and… was that golden dust? What in Tartarus! Just then, a boy stumbled out of the wall. Sydney narrowed her eyes. The boy held up his hands in truce.

"My name is Percy Jackson, and my father, Chaos, wants to see you."

Sydney was confused. "Where are my parents?"

"They're okay. Rogue demigod, and two empousa. Nothing to worry about. Hurry, there will be more attacks. Come with me."

With that, the two of them blinked out of existence.

Chaos's Realm

"Son, do you have her?"

"Yes, Father. She is coming with us now."

"Good."

"Who is she?"

"She is the daughter of Nyx."

Percy let out a strangled gasp. "I didn't know that they could exist! Isn't Nyx like a black widow? Kills her mate or something?"

"Except for her father. He survived the attempt, so Nyx didn't try anything after that. Survival of the fittest."

"Okay…"

"Don't worry, son. Everything is taken care of."

Sydney looked at Percy. "Who in Tartarus are you?"

"I have already told you."

"Where are you taking me?"

"My father needs to speak with you. What happens next is up to you."

A/N #3: And this concludes the first chapter of this story. If feedback is negative, then I probably will finish up this story and end it. Otherwise, she might be Percy's girlfriend? Still unsure, though. Byeeee :)
