Return of the Olympians Chapter 1

(A/N) This is my first published story, so go easy on me I hope you enjoy it, so I will shut up and let you start reading.

Disclaimer: I do not own Percy Jackson and the Olympians, Heroes of Olympus, or anything related to it, except my OC.

For the first time ever, things were looking up for Percy Jackson and his team of demigods. Only a few monsters and one giant remained. Two Hellhounds, an Earthborn, and a gorgon remained with the king of the giants: Porphyrion. The gang was exhausted from fighting. Thalia and Zeus worked together to kill Polybotes after he reformed. Death seemed to have regained some control at his Doors, but monsters were still coming back.

Percy was standing in front of the giant king. Porphyrion smiled, and raised his fist. "Child of Poseidon! You and your friends have fought bravely, however you have lost! Gaea is waking! My power grows to infinite! Surrender and you will be spared from my mother's wrath!" he boomed.

Standing behind him was his girlfriend, Annabeth. She gripped her dagger so hard she could've crushed the handle. Behind them were the gods and goddesses who decided to help the mortals. Athena and Poseidon stood behind the couple, very worried about the fate of their children.

Gaea's voice boomed over the battlefield. "You have defied me at every turn, Son of Poseidon! Surrender yourself to my son, and everyone you care about will be spared!" she demanded.

Annabeth walked up to Percy, who was giving his best death glare at Porphyrion. "Seaweed brain, you better not try anything foolish. Try thinking for once."

Percy smiled. "I don't know, Wise Girl. You got any ideas?"

Before she could suggest something, Gaea's voice boomed again. "There is no escape, Hero of Olympus! You either surrender yourself, or your world will be destroyed."

"Listen to the Earth Mother! Your death will seal the Olympians in the pit of my husband's creation. The seal will break in our favor!" Porphyrion boomed.

Athena gasped. She turned to Poseidon, and grabbed his collar. "Tell me that he doesn't have the seal on him! Your sea spawn better not have the seal on him!"

"What seal? I don't remember putting a seal on him," he said.

Annabeth turned to her mother. "What seal?"

Athena sighed. "When Kronos was defeated in the first Titan War, the Council voted to give the Seal of Olympus to a mortal. The Seal of Olympus is a magical chain that keeps our legacy, the legacy of Greece and Rome, anchored to the world. Whatever happened, if he or she sacrificed themselves in the name of Olympus, Olympians would be put to sleep until someone reawakened them. We've been put to sleep for 500 years by a mortal. It's the best way to keep our legacy alive."

"But all that changed during WWII. When my brothers and I made that pact, we also swore to find and keep the new Seal safe. But we could never find it. It was lost, and only powerful demigods can live with the Seal," Poseidon said.

Horror flew past Annabeth's face. She turned to Percy, who was also concerned. "A sacrifice I cannot make," he muttered.

"As much as I hate to say it in front of you, Annabeth, but Percy is the Seal now. The legacy of the Greeks and Romans live in him now. He either dies by his own hand and we sleep, or the giants kill him, and Olympus is doomed," Athena said.

Poseidon grabbed the wisdom goddess. "NO! You cannot suggest that he is the Seal! He can't be!"

Athena grabbed his hands, and lowered them. "I'm afraid that it all makes sense. His power, his aura is strong. He may even best a minor god if he had the courage. It's difficult to defeat him because the Seal tries to defend itself."

Percy's eyes flashed. He knew what he had to do, and it was risky. "I'll do it."

It took everyone two seconds before they realized what Percy said. Annabeth walked up to him, and slapped him. "You can't say that, Percy! You will not put us to sleep on your death!"

Percy grabbed his girlfriend, and pulled her in for a kiss. His kiss was long and sorrowful, like he knew he had to die. "I'm going to do it. If it means that everyone here will reawaken in the future, so be it. If the giants do it, we all die, and Gaea will reign victorious. There is no other option."

Before Annabeth could protest, Percy stole her dagger, and held it in front of his chest. He turned to the giant king, who seemed to be afraid. "If I die by my hand, you giants will never return, am I right?"

He wasn't expecting Porphyrion to answer, but he did. "If you truly have the Seal, otherwise we reign. You're risking a lot, Percy Jackson. You might have the Seal, or you don't and you will die for nothing!" he boomed.

Percy smiled. "Let's find out, shall we?"

He raised the dagger, and it sunk deep into his chest. "NO!"

His eyes turned black, and the whole world started to shake. Even the god of earthquakes was thrown of balance with the unexpected power of his son. Back on Olympus, the temples crumbled, and the minor gods and goddesses disappeared in a golden flash. On Mount Tam, The ruins of the Titan base sank into the earth along with Atlas. The sky was lifted off of his shoulders, and was lifted into the sky. Hyperborean giants sank into the ground, and even the camps suffered.

Dakota was polishing his goblet for another drink when he disappeared in a golden shower. Nearby campers shrieked in fear, and ran for their lives. Everyone started disappearing, even the Lars and fauns. Soon, Camp Jupiter was gone.

Chiron was teaching his archery class under the New York sun. "You must all remember to—" he disappeared.

The campers looked around, hoping that the Stolls were behind his disappearance. Travis and Conner ran toward the class, and were met with 30 sets of eyes.

"We didn't do it!" they shouted immediately. "Wait, what didn't we do?" Conner asked.

Travis was about to answer, but he ended up being showered by golden dust. Conner shrieked. "Travis!"

He held up his hand, and saw that it was turning gold. "Me." He exploded in a shower of dust. One by one, campers tried to pray to their parents, but evaporated instead. Clarisse and Chris were holding on to each other, and disappeared at the same time. Camp Half-Blood sank into the ground, and nothing was left. Even the strawberry fields disappeared because of their connection with the camp.

Back in Greece, the earth crumbled, and a pit appeared. Tartarus. Porphyrion clung to a boulder with his might, trying not to be sucked in to the pit. "Earth Mother, please! Spare m—!"

His grip slipped, and he fell into Tartarus. "Curse you, Percy Jackson! My revenge will be beyond anything the gods can do! You will suffer!" was the last thing Gaea said before she went silent for the last time.

Poseidon and Athena were watching over Percy while all the other Olympians disappeared. Hazel and Frank were sucked in to Tartarus while Jason sunk his sword into the earth. Piper and Leo flew past him, but he reached out and caught them. He caught Piper, and Leo latched on to her leg. "Dude, what's happening?" he asked.

Piper roller her eyes. "We're being put to sleep, Repair Boy!"

"I can't control the winds. Tartarus is disrupting all of our powers, and it's too strong!" Jason yelled.

Reyna flew past them, and into the pit. "NO!" Leo screamed.

He turned to Piper and Jason. "I have to go. I'm not leaving her alone! Nice life, Jason. I hope to spend my eternal life knowing that we had a blast!"

"Leo, you were a good friend. Even with the Mist that surrounded us last year, we had a blast!" Jason yelled. "Go get her!"

Leo smiled, and released himself. He flew into Tartarus, and disappeared. Piper looked up to Jason, and smiled. "We have to go!"

Jason smiled, and released his grip on his sword. Piper flew up to him, and kissed Jason. They fell in to the pit, embracing for the last time.

Meanwhile, Poseidon and Athena were standing over Annabeth and a wounded Percy. "It's too late. We are the last Olympians left on Earth. We have to go," Poseidon said.

Annabeth broke into tears. "I'm sorry Athena."

Athena turned to the god of the sea in shock. "What did you say?"

"I'm sorry, Athena. 3,000 years of arguing and deception, and I was too proud to say it. I'm sorry for provoking you and turning my girlfriend into Medusa. I'm sorry for threatening war with you, I'm sorry for everything," he said.

Athena smiled. Before she could say anything, she was swept off her feet, and flew toward Tartarus screaming. Poseidon stamped his triton into the ground, and reached out. He caught Athena.

"I've should've said that a long time ago, Athena. I should've looked past our complications and say it all!" he shouted. "Can you forgive me?"

Athena smiled. "I always forgave you, Poseidon. I was just too proud to admit it. Thank you for making the last 3,000 years entertaining," she said.

Poseidon smiled, and released his weapon for the last time. They flew into Tartarus holding hands. Annabeth was stretched between feelings of happiness and pain. Her mother made up with her enemy, and felt so much pain because Percy sacrificed himself.

"Anna-b-beth," Percy whispered.

She gasped, and looked into his eyes. "Percy?"

"L-isten ca-fully. A mor-al needs to enter the Und-world to rele-se us," he said. "Leave a note."

She nodded, and pulled out a piece of paper. She wrote an SOS in Ancient Greek, and it flew into Tartarus. "T-time to g-go."

Annabeth smiled, and she pulled him in for one last kiss. "We'll be safe, I promise," Percy said.

An oath to keep with one's final breath/ and foes bear arms at the Doors of Death. Annabeth remembered the last two lines. The giants bore arms when they finally closed the Doors of Death. Percy promised that they would be safe in Tartarus with his last breath. The prophecy was complete.

The winds of Tartarus grew stronger, and Annabeth and Percy were finally sucked in. They flew into the Underworld, and saw many changes. The River Styx was dried up, Hades' castle was in ruins, and the three sectors of the Underworld were no more. The Ensylum, and Fields of Punishment, and Fields of Asphodel were gone. The only thing remaining was Tartarus, which had Hades in its grasp.

Hades turned to the kids, and snapped his fingers. The winds stopped, for now. "You two do realize that it's not death that will meet you. Everyone connected with Olympus will be put to sleep. That means the mortals who were met by us and discovered our identity," he said.

"So my father?"

"Asleep and safe. Like I said, anyone who figured out who we are will be safe," he said.

Annabeth smiled. Her father and her stepfamily would be safe. Normally, she would hate them for being in her life, but she was relieved that they would be safe.

"We need to disappear, child of Athena. Come," Hades said.

He walked in Tartarus. Annabeth carried Percy, and they jumped in. Once they did, Hades' castle crumbled, and pieces of the castle sealed Tartarus up.
