This is just an idea I came up with that I ended up writing 8 pages for… This is just the beginning so please tell me what you think!

So this is about the idea that Zeus found out about Poseidon breaking the oath when Percy was 6 and in a fit of rage sent the poor boy to Tartarus. He was presumed dead and life moved on. When Nico ,Thalia ,Jason , Leo, Annabeth, Frank, Hazel and Piper were sent down there to close the close the doors of death they run into him and see what Hell does to a person.

Thalia

They were the greatest heroes of their generation, or at least that's what they had grown up believing. They had conquered monsters that few had dared to even look at and had completed quests for the Gods without a flicker of complaint. Maybe they weren't the heroes of legends but they had lived to tell the tale of their quest which was more than others could say.

Thalia took pride in her status as a hero and didn't hesitate to use it to scare the younger campers – she was a teenager so scaring people was her specialty. However, she couldn't help but wish she was just another camper as they wondered around Greek Hell.

She couldn't believe the nerve of the Gods. How dare they send the eight of them down there? No, scratch that, she couldn't believe that they had sent them without their consent. Not even a simple yes or no question was asked before Zeus sent them to fix a problem that was supposedly his fault to begin with. Funny, it always seemed to be his fault.

She looked around at the group of people around her and felt a shock of anger which she sent straight to her father, Zeus. Yes, the daughter of Zeus was stuck underground in the land of mist, shadow and death. Sounds fun right? Wrong.

Heck, they didn't even have a map, probably because that would've been too easy and from Thalia's experience life was never easy. The Gods had informed them that they couldn't give them a map because they weren't allowed to directly interfere with the will of the fates; Thalia assumed that that roughly translated to 'we can't be bothered'.

Why were they down in Greek Hell? What a good question, Thalia let her mind wander back the last meeting they had on Olympus.

~Flashback~

"Demigods," Zeus bellowed Thalia winced at the loud noise raising an eyebrow, "It has come to my attention that the attacks have increased dramatically these past few days." Thalia let her eyes flicker across to the other Gods all of whom look very annoyed, how long had they been trying to convince the King of the Gods of the danger their children were in? How long had it been until he cared?

"We have come to the conclusion that the Doors of Death have been compromised," Athena continued, Thalia let a frown fall upon her face. She had vague memories of Annabeth telling her about the doors.

"By who?" Thalia asked the Goddess preparing herself for the bad news.

"We aren't sure," Apollo answered looking up from his phone for the first time since they arrived. "But it's something not on our side, so to speak," Apollo shoved some headphones in his ears and Thalia could hear the loud notes escaping. Hermes pulled them out and the two dissolved into bickering. 'Men' she thought rolling her eyes.

"Whoever had the door under their control has now got a whole army of monsters and titans under their control, they must be stopped," Athena swivelled her head to meet the gaze of her father with a brutal smile on her lips. Oh dear, Athena seemed to have stolen her father's glory, Thalia grinned putting a hand over her mouth to try to hide the action.

"We can't do it, you see…" Hermes told them trailing of at Zeus' glare. With a loud huff the God turned back to Apollo and began chatting with him.

"It is not in our nature nor is it in the law of the fates to close to doors," Zeus straightened his spine and seemed to force a smile on his face. Once again Thalia found herself thinking longingly of her bed, it was too early for the faff that was currently going on.

"Don't you just need to go to the House of Hades?" Annabeth asked tucking a strand of blond hair behind her ear only for it to ping back in front of her eyes a moment later.

"The doors can't be closed from the mortal side," Dionysus sighed stroking an empty glass of wine, Thalia could only imagine where its contents had gone. Out of the corner of her eye Thalia saw Annabeth grow pale.

"Ok then, where is the other side?" Jason asked stepping forward to stand next to her, Thalia frowned as she stared up at him very annoyed that her younger brother was taller than her.

"Tartarus," Annabeth muttered her voice wearing a cloak of horror.

"'Tartarus' as in the star sign?" Leo asked tilting his head to the side. Annabeth shot him a tired look.

"Taurus is a star sign, Valdez, Tartarus is…." Annabeth trailed off wringing her hands together and watching the shadows wearily, "Hell" she finished simply cringing at the word. Leo blinked before hiding behind Jason as if Hell was coming for them.

"Don't be a wimp, Flame boy," Thalia scolded reaching around to slap the boy on the arm.

"I'm not afraid of Tartarus," Leo denied cheeks bright with fire. Maybe if Thalia embarrassed him enough he'd burst into flame.

"I take that as a volunteer to go and close the doors then? Great, I hope you enjoy your vacation and do send me a postcard," Thalia grinned waving her hand in a goodbye the life drained out of the boy's face and Thalia grinned triumphantly.

"No, we can't go there surely," Jason demanded turning to their father with a look of utter betrayal on his face. Thalia frowned as her and Leo's argument ended.

"What's the alternative?" Athena asked them her gaze fixed on Annabeth.

"We could go live our lives as hermits in the Arctic," Leo suggested.

"Or we could ignore it, maybe if we do it will go away," Thalia pointed out making sweeping motions with her hands in a 'go away' gesture.

"No, you have to solve the problem now before it gets worse," Ares snapped as if he actually cared. The god was probably looking forward to the inevitable fights they would have to endure.

"I really don't see how it could get much worse," Thalia shook her head folding her hand into a fist and placing it under her chin as she tried to look as if she was in deep thought.

"There are worse things in Tartarus than monsters," Athena informed them gravelly, Thalia heard Leo gulp and poked the boy in the ribs muttering 'wuss' under her breath.

"Like what exactly?" Frank moved forward folding his big arms over his muscled chest.

"Our father," Hades drawled appearing out of nowhere, Thalia almost jumped at his appearance but her pride kept her feet firmly on the ground.

"He was destroyed," Zeus dismissed scowling at his brother. Hades was either naïve of the action or he didn't care.

"Kronos said the same thing about us yet here we are," Hades countered sitting down elegantly on his throne, his robes spilled out around him like his own personal shadow.

"All thanks to me," Zeus folded his arms over his chest like an impertinent child. Thalia sent Jason her best 'Oh My Gods' look. Her brother looked away his face crinkling with withheld anger.

"Sorry to interrupt, but shouldn't we formulate a game plan to try to solve the problem," Frank asked blushing right down his neck as the two Gods stared at him.

"We already have," Apollo answered with a shrug.

"Oh great," Leo grinned. "Care to tell," Leo asked after a long moment of silence. Thalia couldn't help but feel like the conversation was running in circles, they knew what they were going to end up doing yet everyone was procrastinating saying it out loud. It was set in stone whether the Gods were going to acknowledge it or not.

"They want a group to go down to Hell to close the doors for them," Thalia explained staring at her father with her spine straight and her gaze blank.

"Tartarus, not hell," Annabeth corrected mildly Thalia turned to stare at her friend clicking her tongue in mild annoyance. Thalia shrugged running a hand through her hair.

"Yes," Athena cut in her eyes shining with a hidden emotion Thalia couldn't grasp.

"Well…how do I put this kindly… not in a million years," Leo drawled staring at the Gods as if they had grown another set of heads. Heck that would've been less surprising considering what the Gods had done in the past.

"You don't have a choice," Ares hissed to her left she saw Leo's arms sparked with fire.

"This isn't fair!" Jason shouted his eyes so dark they made the shadows on Hades' robes look bright.

"It isn't about fairness it's about surviving," Athena folded her arms over one another and placed them on her lap, she peered down at Jason with curiosity.

"If this was about surviving you would've told us about this when you lost control of the doors nearly ten years ago," a new voice snapped. Thalia whirled around to stare at Nico di Angelo, the Ghost King.

"We were only compromised a few days ago," Zeus dismissed but he shifted slightly in discomfort.

"Ten years? It's strange how dates line up isn't it?" Poseidon hummed. Thalia tried to hide her flinch, the Sea God was a big ball of mystery that never ceased to scare her. He hadn't always been like he was rather he used to be a reasonably pleasant person but then this huge fight occurred between him and Zeus, the God had never been the same since.

"That has no relevance," Zeus dismissed while Poseidon curled his hands around his trident tightly.

"You will pay for your mistakes one day, brother dearest," Poseidon threatened. Jason opened his mouth and moved forward but Nico stepped in front of him and shook his head with a wicked smirk.

"Are you threatening me?" Zeus demanded as the sky flashed with lightning.

"No but he is," Poseidon sighed as the shadows shuddered as if they were laughing, or maybe crying. It was hard to tell the difference sometimes. Thalia furrowed her brow, who was 'he'?

"He's dead," Zeus waved off but there was something off in the God's eyes that showed he thought something very different than what he was saying.

"No, brother, he's not and he will come from you. Not this day and not the next but someday…someday," Hestia whispered from her place by the Hearth. Her voice danced around the room like the fire and Thalia found herself relaxing slightly.

"No he won't," Zeus snapped shooting to his feet. "He was destroyed, he's gone and he's never coming back!" The God roared then he turned to their meagre group and without giving them a second to prepare he sent them to Hell.

~End of Flashback~

The group of them had woken up in Tartarus thoroughly peeved off, especially Nico who kept muttering, 'should've stayed at home' under his breath. Thalia snickered when she heard but his death glare had her shutting her mouth quickly.

By her count, which was very dodgy, they had been down there for nearly a week and according to Annabeth they had been lucky not to have fallen down as it takes days to fall from the surface. 'Yeah, lucky,' Thalia had replied but she had understood eventually; the floor of Tartarus was covered in rubbish that had no doubt fallen from the top. It was all mangled beyond recognition, the idea that that was nearly them terrified her to no end.

After that Jason, Nico, Annabeth, piper, Frank, Hazel, Leo and I were sent to Tartarus. Luckily we were magically transported here so we didn't have to do the whole 'falling for days' entrance.

"My legs hurt," Leo complained for the umpteenth time, everyone simply glared at him and he snapped his mouth shut. She chuckled and he scowled at her with no heat. (Is that a pun? I can't tell.)

"Annabeth do you know we're we are?" Thalia asked there group leader as they took a sudden left the daughter of Athena merely shrugged which was, surprisingly, not that reassuring. In dead silence they walked onwards into the darkness, exhausted.

Nico

The son of Hades had spent the majority of his life in the safety of the shadows; he wasn't called the Ghost King for nothing. But even he was getting sick of the tightness of the air and the rumble of the caverns, it really didn't help that Jason let out a gasp of fear every time a chip of rock fell from the ceiling as if the whole place was about to tumble.

In Tartarus it was impossible to tell where to go. It was so repetitive yet every inch seemed more horrifying than the last. Thankfully Tartarus had a sort of eerie glow about it that meant they weren't about to go stumble off a cliff or something – wouldn't that be funny?

They hadn't run into many monsters so Nico was hopeful that Zeus had managed to veil them from their sight but he knew that it was a fools hope – the demons of hell would find them eventually and part of Nico was looking forward to them showing their ugly heads, at least he'd have something he could whack with his blade. He really needed to let off some steam before Nico had to sacrifice Leo as his training dummy, he knew that he wanted to.

They turned around another path into a large opening about the size of a three basketball courts – big but not startlingly so. Nico and the others were all exhausted to the bone and starving. Annabeth hadn't given them much time to rest since they'd arrived; she'd told them that the quicker they find the door the quicker they would be back home. He didn't think that was quite the right logic after all, did the girl really think that they'd just casually stroll up to whoever had control of the doors and by a premium ticket and close the doors?

Ha, not likely. How strong would someone have to be to leash Tartarus under their control without the Olympians able to stop them? Nico knew that something had changed ten years ago. It all linked the opening of the doors, the fight between Zeus and Poseidon, and the mourning of the sea God that had followed.

He was just missing one piece of the puzzle and once he found it everything would become clear. Nico wasn't sure what was going to follow his discovery but he just knew that he needed to find out sooner rather than later, they had already wasted too much time. That was entirely Zeus' fault, there was no point denying it.

Nico was rudely interrupted from his thoughts by the clash of metal on metal as two swords collided. He drew his weapon, rolling out of the way to avoid a fatal swipe at his head, and turned to his attacked growling like a feral dog. In front of them were a dozen or so hell hounds, a few Cyclopes and a towering Titan, who Nico didn't recognise.

Oh yes, Nico grinned, finally. With a smirk plastered to his face the son of Hades reaped havoc upon the demons unaware of the boy who watched him in amusement.

**End of chapter 1**

A.N: Thank you for reading. Did anyone catch the TWD reference? XD

Ok wow my writing was crap when I first wrote this, it was actually painful to read, I'm not saying my writing isn't still crap but it is mildly less crap. I think I'm not permanently stuck in a cringe position because I've cringed so much today. Oops, well this was needed. Actually I just re-read this to make sure I hadn't got any plot holes but this chapter upset me so much I re-wrote the entire thing.

Ok so I've changed the story slightly:

1. Nico did go to the Lotus casino but is still the same age as the others (16) and Bianca did exist and did pass away, urg her death was so sad. Her death will be different from the books but still as traumatic as before.

2. Jason and Thals didn't go the Camp together and met when they were both 13 as a quest clashed introducing the Greeks to the Romans a few years ahead of the original cannon.

3. Thalia was a tree until she was 12 when the Sea of Monster quest occurred. Again it was much different but will be explained.

4. Kronos didn't rise as he needed Percy to do so for reasons that shall be explained later on, Gaea hasn't either but patience children. It shall happen… possibly off camera. I don't know really, it deepens on whether I do a sequel or just an epilogue.

5. I'm not focusing on the re-write as I'm writing an awful lot at the moment and the last thing I need right now is another thing to have to worry about. But over time I shall edit this fic.

Please tell me if you enjoyed this re-write more or less than the original. It really does help.
