(I do not own Lucifer or Percy Jackson)

Percy had a been having some really bad days. It was raining with thunder and the oceans is much more violent, and he had to go to a drunken slob at his home. At least he had Grover and his mother. He was going to a museum with Grover. For some reason he can't explain he could easily talk every language some he didn't even know were from. Writing and reading was a little harder but it came to him easier than other students. The teacher brought him to a private place.

"Give me the lighting bolt Percy!"

"What are you talking about? A lighting bolt?!"

We have to go back in time for this to be explained.

Lucifer Morningstar. Was visiting some Pagan Gods. He certainly didn't mind them even though they despised him. But his father abhorred them. He met them while they were celebrating for something Lucifer doesn't care about. He was bored until he saw a woman Artemis. She had long lucius red hair. She wore a white silky dress.

and she looked equally bored.

Glares were sent to him left and right. Zeus in particular threatened him. He responded with two words.

"Do it." Artemis was amused. As lucifer just grinned. It was around midnight when Artemis approached him.

"So lucifer very bold you you to stand up to Zeus. I bet they hate you even more."

"Yes but what can they do?" He chuckled.

"Wine?" She offered.

"Hmmm delicious. It's better than Jesus's wine for sure." She chuckled. They conversed for hours. Eventually at one point they find each other in a bed.

"Oh Lucifer I love you."

"Artemis no words can express my love for you."

"I'm pretty sure you just did."

They both chuckled. Eventually Lucifer was banished not just from Heaven but from Olympus. So is Artemis. They still loved each other greatly. Artemis decided to to go to hell. They loved each other for centuries. For eons. But one day Artemis got pregnant.

"Artemis to keep the child safe the child should be among the humans It pains me to not be there but this place is nothing for a child, and father would hurt the three of us if I leave."

"Lucifer I will never stop being in love with you. You mean more to me than anything else there is no way to say how much I love you. Once the child is out it will be adopted. It will be in danger I know a human who will take care of him like if the child is their own."

"That sounds agreeable. I'm sorry that we can't be there for him luv."

"Its not your fault luci."

They smile at each other.

12 Years later

Percy is pulled away by a substitute teacher.

"Where is the lighting bilt you lightning thief!"

"What do you mean?"

Then chiron wheels in with Grover.

"Leave you beast or I will kill you!" He clicks a pen and a sword pops out.

"What's going on?"

"Follow me Percy."

They were led out the museum. "Grover make sure he gets home."

"All right let's go percy!"

"Can you explain this to me!"

"I can't right now. But later I will."

MEANWHILE

"Luv I think we should go to earth. I can't stand another second with out him."

"Let's go quickly to the camp love!"

He smiles as he watches her run to the gates.

IN THE CARE

"Mom could you explain thei to me?"

" I think it's best if you get to the camp first."

"Camp!?"

"It will protect you Percy."

"Fine."

Then a minatour throws w cow at the car. Percy climbs out his back hitting the shards of glass. He runs with Grover to find out he has Goat LEGs! The minatour captures his mom. It charges at percy. He dodged but he still hit him. But the minatour stumbled back. The horm cracked off. He kills the minatour with it's own horn. He passes out.

HALF BLOOD CAMP

"I bet they are surprised to see me love."

"They don't know me its oroably for the best."

"Nonsense you are the most amazing being I have ever met." He sees the half horse man.

"Chiron. How is he?"

"He just came follow me." Lucifer follows Chiron. Lucifer sees his son Percy sleeping. He sits down next him holding Artemis hand.

"Uhh who is this Chiron."

"Please leave for now Grover this is a private matter."

"I'm not leaving percy."

"I appreciate what you have done for him. I'll help you get your horns huh if you leave?"

"Uhhh sure?"

Lucufer just snapped his fingers and horns appeared. Grover leaves in amazement.' When could someone do that unless he was a god!?'

Percy wakes up to see a man and a woman.

"Uhhh. Who are you and where is my mom!?"

"Umm Percy this is your mother."

He finally sees it his mother is Artemis.

"My mother is Artemis?"

"Yes indeed."

"Who is my father?"

"Ohh Percy your father is-"

"Is me."

"What's your name?" Lucifer gulped.

"Lucifer Morningstar."

"Your the devil. So I'm the son of Artemis and the son of lucifer?"

"Yes." Lucifer said shakily.

"I'm glad your here." He hugged his father. Lucifer heart warmed. Artemis heart melted.

"Do I have siblings?"

"No after I met Lucifer I stayed with him. I have been with him for eons. Since he was the devil. We are banished from heaven and Olympus. Then lucifer was forced to return to hellm I followed. Then we had you. Hell was no place for you Percy. So I made sure you were adopted and made sure you wouldn't...die."

"Its okay."

They walked out. They thought Percy should be in Hades cabin. But Percy repsonded," Its just a weaker version of my dad." Lucifer smirked at his response. So Lucifer decided to snap his fingers and create a house on the edge of the beach. With a dock. Percy loved it.

Then a bunch of students came to him.

"Hey loser what's your name!"

"Lucifer Mornigstar the Archangel and one of the most powerful beings in the universe." He said and his eyes turned on fire. All of them ran away.

10 years later

Percy is 22 and he started a cabin for his siblings. Ever since lucifer and Artemis resided at the camp. They felt safe to start a family. Right now they had twins. They were 19. A son that was 16. Another son that is 14. And a daughter that is 10. Then another daughter that is 5. All of them were strong and held strong abilities like the immortalness. All of it under Gods nose. They had an encounter with Zeus. But after they fought Zeus clearly backed away. Castiel, Gabriel, Azreal and Ariel had been invited them to his wedding. He trusted them to not expose him. They hung out and talked for hours. They loved artemis. She still had red shiny hair. And wore white dresses. With yellow bright eyes.
