Disclaimer: I do not own Percy Jackson.
Percy
"You will never win!" Gaia screamed in rage. "I am not a god! I cannot be defeated by a mere child! I am a primordial!" Percy gritted his teeth, summoning enough strength to perform his final trick. He channelled all his strength and power into his sword, Riptide. Percy thought of the gods almighty, letting Riptide suck up all his happy memories. Percy's sword glowed a bright golden, and erupted into a burst of light as it was plunged into Gaia's chest. The look of triumph on her face contorted into a series of creases as she screeched, "No! No! Nooooo!" Gaia crumbled into soil that sunk into the earth. Percy collapsed. He heard the screams of Hazel and Annabeth's wailing. Everything was fuzzy and the world went black.

Annabeth
Tears rolled down her face. Annabeth sifted the sand that was left of her boyfriend through her fingers. Her heart was about to crack apart. Percy had sacrificed himself to save Olympus, although the gods merely praise themselves for the defeat of Gaia. The mood in the Olympian throne room was sober as everyone mourned the deaths. Annabeth's heart was filled with something else; hate. Hate at Percy. He had vowed on the River Styx that as long as he loved Annabeth, he would never leave her no matter what. That must mean that he did not love her anymore, letting death pull them apart.
At that moment, a flash of light interrupted Zeus' speech about how good the gods were. A man in a pristine white tuxedo stood in front of the king of the gods. Annabeth's mother, Athena the goddess of wisdom, gasped and bowed to the man. Zeus was furious as Athena never bowed to him, much less a stranger. "What do you want?" Zeus asked the man angrily. The man simply smiled, as if Zeus was something that he found amusing. Zeus hurled his master bolt at the man at full speed, but the man yawned and snapped it in his fingers. The whole throne room was in shock. The man grinned and whipped out a parchment of paper, and said,"I am here to answer Percy Jackson's request." Annabeth shouted," Why would Percy collaborate with a man like you!" Everyone in the room shouted in agreement. "Percy wanted the casualties of the war to be brought back so that everyone would be happy." the man replied calmly. "Leo Valdez, Piper McLean, Zoe Nightshade, Conner Stoll, Bianca di Angelo..." As the man said every name, the person who had the name appeared next to him. The friends of the revived rushed to hug their friends. Annabeth was running towards Piper when someone else appeared next to the strange man and her vision tunneled. Annabeth ran up to the boy with sandy-hair and gave him a passionate kiss. "Luke..." Annabeth whispered. "I'm back Annie, I'm back." Luke whispered as he caressed her cheek. Their lips met and they did not pull away for what seemed like hours. They were interrupted by the man saying,"Well. I am Order. Percy Jackson faded into the Void, an endless abyss, so that he could bring you all back." Everyone in the room went silent again as they mourned their hero. Order nodded his head and disappeared in a cocoon of light.
