It's my first time actually writing down my ideas. I mostly just let them float around in my head 'cos I have zero self-esteem and writing down my ideas is asking for trouble.

This might be brilliant. This might be trash. I'll let you decide.

Jason slew the monster in front of him with a slash of his blade, and took a brief respite. The war raged all around him, and he spotted Gaia in the distance, awake and laughing with glee. He spied Percy and Annabeth in the middle of the fray, right next to where Gaia was. A chill ran up his spine, and he couldn't stop a feeling of foreboding coming over him. Spurred on by the dread in his gut, Jason moved to help his friends.

He didn't make it in time.

He watched, almost as if in slow motion, as Gaia's henchman thrust a blade through Annabeth's abdomen. He could almost hear the disgusting squelch as the blade retracted, and Annabeth's small gasp. The thud as she fell to the earth echoed in his ears, despite him being so far away. Time stilled and the wind whistled in his ears.

"ANNABETH!" Percy's strangled yell broke through Jason's clouded mind. He saw the grief in Percy's face, soon overcome with rage. His light green eyes turned so dark, that from where Jason stood, he could have sworn they were black. The lover's face twisted into something that froze Jason where he stood, and in that moment he couldn't recognise the Percy he'd come to know.

Then all hell broke loose.

Percy roared, loud enough to let the heavens know his pain. The monsters surrounding Jason froze, though the boy had absolutely no idea why. Then they began writhing and screaming in pain, streams of blood pouring out of every entrance to their bodies. Rivulets of red streamed out of their noses, mouths, eyes, ears, joining a river of blood that amassed behind Percy.

Jason wanted to throw up when he realised what exactly Percy was doing.

Fortunately, his stomach managed to stabilise, and Jason watched as dead bodies slumped to the ground, one after the other, dry and sickly looking, before disappearing in a cloud of golden dust. Percy had taken down all of Gaia's army in less time it took to butter toast.

Jason thought back to when he'd challenged Percy to a fight, and almost did throw up.

Now the only people left on the battlefield were the demigods, gods, and Gaia. All of Percy's attention was fixed on the primordial. The blood he'd collected was gathered behind him, writhing and boiling like some sort of cloud of death. That, paired with Percy's half-bloodied, crazed face, had the demigods trembling in their boots.

Gaia, unnerved but still confident, stood in front of Percy, his apparent craving for her blood not putting her off in the slightest.

"Very well done, Percy," she drawled. The blood behind Percy began to boil. "I must say, I'm impressed," she flashed a feral smile, "but I'm afraid it's going to take a lot more than that to defeat me."

Percy met her eyes with defiance burning in his own. "You shouldn't have hurt her."

Jason felt a small tremor in the earth beneath him.

"That was your mistake."

The trembling was getting stronger now. Jason fell to his knees, trying to brace himself against the earthquake. Geysers of water exploded all around the battlefield, causing Jason to flinch.

"You're gonna regret it."

Percy launched himself at the primordial, riding on a wave of blood and water. His and Gaia's blades clashed with a loud clang, and off they went. Jason couldn't see their swords, they were fighting too fast for his eyes to follow. One thing was for sure though, Percy was on a warpath, and he wouldn't stop until he destroyed the primordial or died trying.

Jason dreaded it would be the latter.

Gaia was laughing, mocking Percy with each thrust of his sword. "You can't hurt me, Percy. I am the earth itself. You'd have to destroy the whole earth to destroy me." There was no doubting the obvious glee in her voice.

Percy's grin in return was feral, and Jason was reminded of a bloodthirsty wolf.

"You might be the earth, Gaia, but you forgot something."

Something was happening. Gaia was rising into the air, as chains of water and blood lifted her body above the earth. No matter how much she squirmed or struggled, she couldn't escape. Tendrils of dark earth tried to reach her from the ground below, but Percy blocked them with the sea of water. Clumps of mud fell back to the ground, and Gaia grew more frantic.

"I'm the earth-shaker."

Anaklusmos pierced Gaia's heart and her mouth opened in a silent scream. Ichor flowed out in bursts, and there was gold streaming out of her mouth. Jason wanted to look away, but he stood, transfixed, as the primordial breathed her last. The waves holding her up disappeared and she fell, getting swallowed up by the ground as soon as her body touched the earth.

Percy landed on the ground far more gracefully, riding down on the wave of blood and water. The liquid seeped back into the earth where it had come from, leaving Percy behind. The boy's eyes searched frantically before stopping on a body crumpled on the ground, blonde hair scattered everywhere.

Guilt crashed into Jason like a truck – he'd completely forgotten about Annabeth in light of Percy's spectacular display of power.

Percy, however, had not. He raced to Annabeth and collapsed to his knees next to her small frame. Gently, he turned her body so that her upper body rested in his lap and her head was against his chest. He could feel her shattered breaths against him – she was still alive.

Her eyes fluttered open and she looked at Percy with such adoration as if he was the greatest thing she had ever laid her eyes upon. When she spoke, it was more of a weak whisper and in much contrast to her usual strong, commanding tone she normally held.

"Percy." She was smiling, a soft, feathery smile that lit up her eyes with more life than she had currently in her whole body. "You did it, Percy." Her breaths were getting shallower. "I always knew you could." It was getting harder for her to keep her eyes open.

A sob racked Percy's body, and her pulled her even closer to him. "Hey, yo-you're gonna be ok, alright? We'll get you nice and fixed up and-and then we'll go for a walk by the beach an-and then-then you can call me a seaweed brain for not knowing anything at all, 'cos I'm not as smart as you Annabeth, I need you, Annabeth, I need you, you're my wise girl, I can't – please, Annabeth, I can't –"

Percy broke down into sobs, clutching Annabeth's body, looking at her face, begging her to realise he wouldn't be able to survive without her. She only smiled back softly in return. Her breaths were getting shallower, and she knew it wasn't too long now, and then she'd wouldn't see him again for a long time. But there was something she needed to say first.

"Listen, Percy." His eyes met hers, and her heart broke seeing the desperation in them. "You're strong, Percy, the strongest man I've ever met. You'll get through it, ok?"

"I can't, I can't, not without you, please Annabeth –"

She shushed him, and smiled gently. "Yes, you can, Percy, I know you can. If anyone can, it's you. And this isn't goodbye, Percy. We'll be seeing each other again." She smiled, but then glared at him lightly. "But that'll only be when you're old and grey got it? With a wispy beard and creaking bones."

The chuckle he gave was half-hearted at best, broken with sobs and tears. It wasn't what she'd hoped for, but it was something.

"You need to live, Percy. Live for me. For us. I know you can, Percy, I've seen you do it before."

The end was getting nearer now. They both knew it. Neither of them could admit it.

"I love you, Wise Girl."

"And I love you, Seaweed Brain."

He leaned down to kiss her, trying to will his desperation into that one final locking of lips. When he pulled away, it was far too soon.

She looked at him with warmth and love. He didn't want her to look away, didn't want her to ever stop looking at him like that. He didn't think he could handle not seeing those beautiful grey orbs again.

She closed her eyes.

They didn't open again.

Percy stopped breathing for what seemed like eternity. His eyes were glued to her face. This was a trick, right? Any second now, she'd open her eyes and then Will would get her fixed right up and then they'd go down to the beach for a swim, and forget about everything that happened here. Right?

Even as his heart begged for it to be true, for her to wake up, he knew she wouldn't. And his heart broke even more still.

"No." At first it was a whisper, but it soon turned into sharp, pleading cries as tears made their way down his face and his throat clogged up and his breathing became more laboured. "Nonononono, please Annabeth, hey, look at me, please, Annabeth, please, hey, just look at me, Annabeth? Please, Wise Girl, I can't lose you too, please, just open your eyes for me sweetheart, please, just, Annabeth? Annabeth? Please! Annabeth! Please, please, Annabeth, please!"

Percy looked up, as if to plead with anyone standing by to convince them to help him wake her up, but then he caught sight of Nico. When the younger boy shook his head, his own eyes brimming with tears, it was the final blow for Percy.

He broke down completely, sobbing and screaming and pleading, all the while clutching Annabeth's body even closer. He tried very hard not to think about how her body was already losing its warmth.

He would have stayed there forever if he could have, clutching Annabeth's body, tears streaming down his face and dripping onto the body of the girl he loved. But it was not so.

After what seemed like forever, Jason stepped up and laid a hand on Percy's shoulder, squatting down so he could be level him.

"Perce?"

Percy's face was buried in Annabeth's curls. It was a statement to how long they had been standing there, as Percy's sobs had all but died down and all he was doing now was clutching her body and rocking back and forth.

Jason bit back his own tears, at seeing one of his friends dead and the other so broken. Piper, Hazel, Frank and Leo came closer, along with Thalia and Nico. None of them spoke, wanting to show their support through something worth more than words. After a few moments, Hazel addressed Percy, whispering softly.

"Percy, we have to get her back to camp, so we can bury her properly."

No response.

"Perce?" She spoke gently, as if speaking to a small child. A long moment passed where Percy made no indication he had heard her, but then he slowly nodded, his face still in Annabeth's hair.

Slowly, making sure he didn't accidentally hurt Annabeth, Percy stood up. Annabeth was in his arms, and looking at how he was carrying her, it could have been thought that she was merely asleep. It reminded Hazel of older, happier times, and a traitorous tear made its way down her cheek.

"I-" Percy's voice was croaky with how much he'd been crying and he had to clear his throat before speaking again. "I'll carry her back." He looked ready to fight anyone who would disagree, but no one dared to anyway after what they'd seen him do.

He strode forward, limping slightly after having stayed in position for so long. The other followed behind him, a silent procession for their lost friend. They followed him right back to camp, back to the infirmary, until he lay her on the white sheets of a cot. Then they were there for him when he broke down again, holding him close when he sobbed into their shirts.

All of them shed tears long into the night. They had been strong for so long. It was alright to be weak for a little while, and let someone else be the strong one for a change.

… 1 month later …

Demigods, both Roman and Greek, stood on Mount Olympus before the Olympian Council. All of them had been through the war with Gaia, and each of them had suffered more than any child should ever have to suffer. Each of them had also been rewarded in kind – the greater their part in the war, the greater their reward.

All except one.

Percy stood in front of Zeus' throne, feeling kind of underdressed in his camp t-shirt and shorts when almost everyone else had worn someone more formal. He'd forgotten today had been the long-awaited meeting with all the gods, and he'd been in a mad rush to get ready in the morning after having slept in. He was just lucky his shirt wasn't inside-out.

"Perseus," Zeus called. Percy resisted the urge to roll his eyes. "For your bravery in this war, and for your vital role in defeating the enemy -"

"That's an understatement," someone cut in.

"- the gods have decided to gift you 3 wishes. Ask anything of us, within reason, and it shall be granted to you." Zeus flashed Percy a rare smile, and Percy was pretty sure he was hallucinating. His missed breakfast was probably messing with his head. "Anyone present here knows you deserve it, Perseus."

Percy looked around at the gathered council, and at his friends crowded at the back. They gave him reassuring smiles and Leo threw in a thumbs-up. He smiled before turning back to Zeus.

"Well, my lord, first I'd like to ask you to fulfil your last promise you made to me, to bring back Calypso." Percy narrowed his eyes at Zeus. "You didn't do as I said last time."

Zeus met Percy's eyes with a sheepish look on his own. "Very well."

There was a flash of light, and there she was, standing right before Zeus' throne, a startled look in her face and weeds clutched in her hand. Apparently they'd caught her when she'd been gardening.

Percy grinned when Leo raced forwards, and caught the surprised maiden in a fierce hug, and then caught her in an equally fierce kiss.

Leo broke off and looked to Percy. "Thanks, dude." His voice seemed kind of croaky, as if he was holding back tears. "Thank you."

Percy could only give a bittersweet smile in return. As Leo walked back to the crowd, Calypso's hand clutched tightly in his, Percy spied the fireplace out of the corner of his eye. Hestia smiled encouragingly at him, and he turned back to face Zeus.

"Give Hestia and Hades thrones on the Council."

Zeus raised an eyebrow. "Pardon?"

The son of Poseidon didn't back down. "You heard me. Those two offered more help to us in this war than the lot of you combined. If anyone deserves it, they do."

Zeus held his gaze for a moment before sighing heavily. "Very well."

Two thrones, one made of flames and another of dark shadows, rose out of the ground and added themselves to the semicircle. Hades gaped at Zeus, then turned to gape at Percy, who smirked at his gobsmacked expression. Hestia grinned and gave Percy a heartfelt hug before ascending to her throne. Hades followed his older sister as if in a trance.

Percy grinned and looked around at the throne room. Everyone grinned back at him. They were happy. What more could he ask for?

"And for your third wish?"

Percy thought for a moment before smiling wryly. "You don't suppose there's any way to bring her back, is there?"

A sombre mood settled over the throne room, and the gods looked at Percy with a mix of pity and sadness.

"I'm afraid that's not how it works, son," Poseidon murmured, his heart going out to his child.

Percy fixed his eyes on his feet. "Yeah, I guess not." He cleared his throat and looked up to meet Zeus' eye. "I have no other requests, Lord Zeus."

Zeus furrowed his eyebrows at him. Then looked at each of the gods in turn. Percy looked at the Olympians and watched in silence as they seemed to be conversing silently in their minds. Ares was glaring at Zeus, and Poseidon was wearing the brightest smile Percy had ever seen. A few more gods shifted in their seats, wearing varying expressions of hope, excitement and mistrust.

When it seemed to Percy he would fall asleep standing up, Zeus cleared his throat and he snapped back to attention.

"The council has come to the decision that you have not been rewarded enough for your victory in this war. We have graciously decided to gift you with the Blessing of the Gods, and we hope that you will use this gift wisely and will not abuse its power."

Percy's eyes widened in alarm. "Whoa, wait, now hold on a minu-"

A bright flash of light, excruciating pain, and then Percy knew no more.

… 2 months later …

Percy sighed, tired from his long journey. He may have Zeus' blessing now, but that didn't completely drive away the fear he had of flying in his domain. For the first hour of his flight, he'd clutched the seat so tightly, he was sure there were now hand-sized dents in the seating. After he'd been reassured that no one was going to smite him down, he'd relaxed slightly and even enjoyed the feeling of flying through the skies nearer to the end of his journey.

Now he was standing at the airport terminal, waiting for his aunt from his mother's side to pick him up. He was in London, England, far away from home. After the whole fiasco in the throne room, Percy had taken a break from camp and moved to his mum's apartment. There he'd spent two months healing from the physical and mental wounds of the war, and the loss of Annabeth, before he and his mother had decided he wasn't about to catch a break holed up in a small apartment complex. She'd informed him of her family history, how she'd moved away from England when she herself had felt suffocated with her family. She'd had two sisters, one of which was dead now, but the other had agreed to take in Percy for the remainder of the year. His aunt, Petunia her name was, was married and had a child only a few years younger than Percy, and Percy hoped they would become friends.

He'd also heard that his other aunt, the dead one, also had a child that Aunt Petunia was taking care of, and he too was about his age. Maybe the three of them could all hang out together? He sure hoped so, it would be nice to have a few friends in a foreign country.

"Hey, you Percy Jackson?"

Percy looked up to see who had asked. It was a rather round fellow, with sweat sticking to his forehead and beady eyes that reminded Percy of a shifty snake. He sported a bristly moustache and his shirt was straining in the effort to keep his stomach in, and he was about a head shorter than Percy.

"Yep, that'd be me. And you are?"

"Vernon Dursley, your uncle." The man, now identified as Uncle Vernon, turned around sharply and made to leave the airport. "Hurry up, boy," he threw over his shoulder. Percy grabbed his bags and made after him, catching up in no time with the man's rather slow gait. Uncle Vernon didn't attempt to make any small talk as they made their way to the car, so Percy kept quiet. He wondered if Aunt Petunia was also like this.

He didn't have to wonder long, as she was waiting in the car for them. She was very different from her husband, much taller and also much skinnier. She made a face at him and Percy realised after a second that she was attempting a smile. Percy managed a hesitant one of his own.

"Nice to meet you, Aunt Petunia."

The smile was beginning to look more and more like a grimace. "Absolutely wonderful to meet you, dear." Her high-pitched voice grated on Percy's nerves, and it took all of his willpower not to flinch. "I hope your flight went well?"

"Yes, it went as well as expected."

Percy bundled into the car and they sped off. As he watched the surrounding countryside fly by, Percy wondered just what he's managed to get himself into this time.
