I do not own Harry Potter or Percy Jackson.

Prologue II: Origins

From the moment Lily Evans Potter found out that she was pregnant, she and her husband both knew there was a chance that the baby wasn't James'.

During their honeymoon, they had not exactly been chaste. During their month-long sojourn across Western Europe, Australia, and North America, several people of various genders, nationalities, and species had shared their bed. Lily called it "a last dip in the pool of hedonism before our return to responsibility". James just called it "fun". Whatever the case, they realized very quickly that there was a distinct possibility that James was not the baby's father.

Lily was horrified. James was mildly worried but swore that he'd blood-adopt the baby anyway, and he or she would be just like their biological child. He would even make the baby his Heir in blood and magic, even if he or she was not born of Potter blood.

When Lily was four months along, the baby had developed enough for the spells to detect its gender and parentage. They decided to test the gender first, and were given the news that they were expecting a daughter.

The second test did not have such pleasant results.

While Lily Margaret Evans Potter was listed as the mother, the father was listed as Meallán Bolt.

All three present stared at the name.

Finally, Sirius asked, "Do you even remember Meallán Bolt?"

Lily slapped his arm.

"Ow!" the man yelled. "Why are you hitting so hard?"

"That would be Lily's way of saying, 'Yes, Padfoot, we remember Meallán Bolt. We vetted everyone before we slept with them. We didn't want to accidentally sleep with a Death Eater, after all," James sighed. "Meallán Bolt was a half-blood, the son of an Irish wizard and an aura, a Greek wind elemental. We met with him in Australia, of all places, and spent a few days hanging out with him."

"And now he's the father of your kid," Sirius said with a nod. "You going to tell him?"

"How are we supposed to find him? It's not like we exchanged contact information," Lily said, frustrated.

"It'll be better if we don't," James said with a nod. "Besides, after the blood adoption, she'll be as good as mine anyway. Just because she doesn't have my blood doesn't make her any less my daughter. I love her, and that's what matters."

Lily looked at her husband with teary, adoring eyes.

"Oh, James," she said. He wrapped his arms around her, and she practically melted into his embrace.

"I still get to be the godfather, right?" Sirius asked.

Without leaving James' arms, Lily reached out and smacked him.

"OW!"

CHRYSOCOMÊKATACHTHONIA

When she was born, she was perfect.

The newest addition to the family had messy black curls, pale skin, and emerald green eyes. With her coloring, and the fact that James' mother had curly hair, they were easily able to pass little Amaranth off as James' daughter.

They did not fully segregate her from her conception. Since her biological father was the son of a Greek nymph, Lily suggested that they give their little princess a Greek middle name. Sirius suggested Chrysocomê, which was simply a translation of Amaranth into Ancient Greek. Therefore, their little darling was named Amaranth Chrysocomê Potter.

Their life was perfect.

Then Dumbledore showed up and told them that Amaranth was one of two possibilities for a child prophesied to destroy Voldemort, and that the Dark Lord was fully aware of that fact.

They had left their home almost immediately to go on the run, and they had remained on the run for more than a year. Finally, shortly before Amaranth's first birthday, Dumbledore brought forward the idea of using something called the "Fidelius Charm". It would allow them to remain in one place to raise their daughter, and they would not have to be constantly looking over their shoulders.

They agreed, and told everyone that they were choosing James' best friend, and Amaranth's godfather, Sirius Black, as the Secret-Keeper.

Just before they were ready to do the spell, Sirius came to them and recommended a different course of action. Instead of using him as the Secret-Keeper, they would use Peter Pettigrew, but not tell anyone. That way, Voldemort would only think to target Sirius, and Peter and the Potters would be safe.

It had been the perfect plan, Lily thought as she ran up the stairs. Except for the fact that Peter – sweet, shy Peter – was the spy who had been leaking information to Voldemort.

From below her, she heard Voldemort yell, "Avada Kedavra!"

She felt tears began to fall down her cheeks as she heard the thump that was her husband's body hitting the floor.

She quickly made her way into the nursery and placed her daughter within her crib.

"I love you, Amaranth," she said, tears choking her up. "Mummy and Daddy love you very much, and we're so very sorry that we're not going to be able to see you grow up."

She closed her eyes, took a deep breath, and invoked, "Zeus Olympios, O Great God Zeus, ruler of the heavens and earth, son of Kronos, son of Rhea, come to me. Lord of Thunderbolts, I invoke thee, Great God Zeus. I am Lily Potter, and my child is yours also. She is going to be killed. I offer my life as a blood sacrifice for hers. Please, protect my daughter."

She heard footsteps behind her, and whirled around to see Voldemort entering the room, wand out and pointed at her.

"Step aside," he ordered her.

"Not Amy! Please…have mercy…" she begged, hands clutching the railing of the crib behind her.

"Step aside, you foolish girl," Voldemort hissed. "Step aside!"

"Have mercy…Not Amy! Not Amy! Please – I'll do anything!" Lily pleaded.

Voldemort sneered.

"Then die! Avada Kedavra!"

A green light rushed toward her, then Lily Potter knew no more.

CHRYSOCOMÊKATACHTHONIA

Voldemort pushed the mudblood's body out of the way with his foot, then moved forward to look at the child prophesied to be his doom.

"Pitiful," he sneered as he took in the jet-black curls and emerald green eyes. "Such a little thing is supposed to be able to oppose me? ME? I am starting to believe that the supposed "Seer" was merely a drunkard. But no matter. You will not be a problem any longer."

He pointed his wand at the babe, and called out, "Avada Kedavra!"

Before the spell could reach the child, the image of lightning appeared before her. The spell struck the lightning, and while part of it was pushed back against the babe's brow, causing her to cry out, even as the rest of the spell reflected on him, turning his body to dust.

The last thing he saw before his spirit was forced out of the house was the inflamed cut in the shape of a lightning bolt on the child's forehead.

AN: So...this was short. Really short. I promise that everything else is at least twice this length.

Originally, this was the prologue to the "Amaranth Potter" part of the story, which would alternate chapters with the Chrysa plotline. It's still the prologue to the Amaranth Potter plot, but I don't actually have any interest in writing the Amaranth Potter plot, so...I won't. The next chapter is the SparkNotes version of the Amaranth Potter plot, which is mostly similar to the actual Harry Potter plot.
