AN-I know most people hate Authors Notes so I'll only do ones where necessary or when important info is to be shared. This Fanfiction is my first but I have written other stories and am told I'm a relatively good writer for my age. I would like to mention a few stories I've read that have given me inspiration and ideas; The Queen's Champion, Everlasting Promises and Betrayed Hero. All great stories, please check them out, they won't disappoint.

Disclaimer: I do not own Percy Jackson and The Olympian Characters or Plots. Neither do I own The Heroes of Olympus Characters or Plot. I am simply expanding on the marvellous work already set in place by my writing idol, Rick Riordan.

Chapter 1: The War; Part 1

Percy P.O.V.

I'm Percy Jackson Son of Poseidon and right now I'm fighting for my life. Gaia and her army of monsters and legion of giants are fighting against eight demigods for control over the Doors of Death, placed conveniently at the bottom of the mountain the original Olympus is built on.

The odds are roughly 2000 to 1 giving us a huge disadvantage all ready. Also, the giants, most powerful of all monsters, won't die unless a demigod and god work together to kill it and right now there isn't a single god insight. If that wasn't bad enough, until we close the doors, every slayed monster will just keep reforming.

Believe it or not Annabeth and I are still inside Tartarus and have made it to the godly entrance to the Doors of Death. We're fighting back to back, protecting each other as well as ourselves from the attacks of oncoming monsters.

"Just like old times, isn't it Annabeth" I yell, making myself heard over the noise of clanging metal and shouting monsters. You'd be surprised just how loud I can be when I need to.

All of a sudden, the monsters, realising their not getting anywhere with their current tactic, retreat, giving the heroes a brief respite. Despite the situation Annabeth can't help but smile at my foolishness.

"We're fighting for our lives and the safety of the world and you can still act like a child Percy." She pants back.

"Just as you can still correct me Annabeth." I retort before slashing at a monster trying to sneak up on us from behind marking the end of our break. It quickly dissolves into a fine golden powder, before slowly starting to reform. Immediately I kicked the pile of dust, stopping it from having a quick reform.

I go back into battle mode before charging straight into the monster army, slashing feinting and blocking for all my worth.

I stabbed at a pouncing hellhound, before turning and coming face to face with a Cyclops wielding a spear. I swiped at the Cyclopes neck, whilst he easily intercepts the strike with ease due to his strength. He thrusts his spear at me aiming at my waist. I then sidestep around the spear before taking advantage of my undefended foe.

Pushing the spear further forward, causing the Cyclopes to trip, I stabbed him through the neck before pulling Anaklusmos back out just in time to turn around and block three sword strikes that would have easily cut me into thirds.

Struggling to overpower three Cyclopes, I pull back my sword, swing it in a 360 turn before feinting a shot to their chest then pushing back up. This move pushed up all three swords, leaving all of them undefended. I take advantage of this and make a swipe at their midsection cutting cleanly through all three monsters before they turned to dust. Looking up I realised that myself and Annabeth had been surrounded.

Slowly the circle of monsters started to edge closer and closer to us. I raised my sword in defence, as did Annabeth, preventing any easy attacks. Some of the monsters would rush out, trying to surprise us. Each cheap shot block and quick attacker was dealt too. We wouldn't make it out unless I could kill them all quickly and soon. I was tired by now and knew my energy would disappear completely if I managed to use any of my water powers at all

"Use the water, regardless of the danger." I heard an unfamiliar voice echo in my head.

After a moment of turmoil, I came to the conclusion that I really heard did just here someone communicate with my mind. So I decided to try talk back.

"I cannot. Doing so would be suicide. If I tried and it didn't work, which is highly likely, then, any and all remaining energy would abandon me." I replied.

"Trust me my boy, this must be done." He stated once more with a finality in his voice that left no room for an argument.

"Okay" I muttered, sounding less than sure with this plan.

I look up once more and notice that the circle of monsters surrounding us has gotten significantly smaller. I knew I would have to call upon my power over the sea and ocean. After a moment of worrying searching I finally feel the familiar tug in my gut was a relief. I made a quick punching motion with my hand and almost immediately an ocean full of water started to rush through the Doors of Death.

The army of monsters was instantly decimated not leaving a single monster alive. Then using what little energy he had left, Percy manipulated the water to pick up the dust and sweeping them to sea, preventing them from reforming.

"Let's go help the others" Annabeth told me. Because she was still facing the other way she hadn't realised just how tired he I was. Before I can even think of following her already retreating form, my legs give way and I collapse to the ground out of pure exhaustion. I land with a loud "Thud!"

"Percy. Oh no, I'm so sorry. I should've known that you'd be tired after that." Annabeth calls to me as she makes her way back to my barely conscious body.

"Here. Let me help you up." She states, worry evident and thick in her voice.

"Come on Percy, hurry." She says whilst pulling my arm around her shoulder. Once she's lifted me off the ground I had to put all my weight on her otherwise I would collapse a second time.

As we near the exit out of Tartarus, we see just how outnumbered we are for the first time. The other five of the Great Prophecy and Nico were being pushed back and up the mountain, meaning the army of monsters are closing the distance between them and Olympus all the time.

"Annabeth. We must hide. Take us over there, inside that cave." After about a minute of walking we finally reach the cave.

"Leave me here Annabeth." I whisper softly, any louder and I'd pass out for sure.

"No Percy I'm not leaving you." She replies.

"Go Annabeth leave me here. If you collapse the entrance then I'll be safe here. Go and help." I repeat, more firmly this time. She looked like she was about to answer no again, so I cut her short with a glare. A strong glare that meant I would take no argument.

"Go, Now." I yell. The last thing I see before I blackout is the mouth of the cave collapsing, sealing off the entrance and exit to the world beyond.

Jason P.O.V.(During Percy's P.O.V.)

I'm Jason Grace, Son of Jupiter and Praetor to the 12th legion, Roman Fulminata. Me and my friends are being backed up the mountain of Olympus. We won't win this fight unless we get help from the gods and the gods will not give us help unless we can close the Doors of Death which we need an immortal being to do safely. So, yeah, unless we get a Gods help, every monster we kill will just reform.

Fighting beside me are four more of the prophecy of the seven, Leo Valdez, Son of Hephaestus and Fire user, Piper Mc'Lean, Daughter off Aphrodite and Charm Speaker, Frank Zhang, Son of Mars and Descendent of Neptune and Shape shifter and finally Hazel Lavesque, Daughter of Pluto. Also fighting with us is Nico Di'Angelo Son of Pluto, or Hades, whatever it is. The whole Greek-Roman thing is still confusing.

Anyway, back to the fight. Nico is summoning skeleton warriors to help us, I'm slashing away up front taking on any early attackers, Leo is just behind us smashing any that get past me as well as shooting balls of fire into the army every so often. Piper is at the back calling out with her Charm Speak, confusing the monsters, giving us time to attack. Frank is directly behind Leo in the form of a Dragon killing all else and protecting Piper whilst Hazel is on Arion, Calling jewels and other precious metals as well as slicing up any other monsters in her reach with her Spatha.

As much as were fighting well, we keep creaking backwards, the number game coming into play. Unless we close those Doors, were not going to make it out of this one.

I block a blow from an Earthborn then send electricity through my sword, stunning my enemy before decapitating him the kicking the dust away. I look up and see the monsters getting ready to make a coordinated attack. Knowing that I have no other choice, I summon lightning, thunder and rain. Putting all my energy into what power I have left, I make the biggest storm I've ever made. Just as I'm about to strike, I see the entire ocean that was behind us lift. It then snaked its way to the Doors of Death and the busted through, no doubt killing every monster in there.

"It's Neptune. He's come to help us. Guys we've got a god to help us. We could win this." I shouted overjoyed by the thought of living past this day.

"That's not Neptune or Poseidon Jason. That's Percy." Nico muttered.

"How can he have that much power Nico? It's impossible, right?" I said, still in awe of thinking a demigod could hold this much power.

"No. It's Percy. I can tell. Posei-Neptune would be here himself otherwise." He called back.

Without wasting another moment I called down the lightning and rain from the storm clouds I had been making. This put a huge dent in the army of the monsters, but we were still hopelessly outnumbered. Just as I was about to use the energy I'd preserved to scatter all the monster dust already beginning to reform, the water rushed out again gathering all the dust before sweeping it back to where it was resting before.

"Nico." I called up to him. " I'm going up top with Piper to rest for a moment."

"OK, just go." Is all I got in response from Nico.

Nico P.O.V.

The trick Percy had just pulled with the water was truly amazing but I had no time to marvel at it because just then I saw Annabeth helping a very weak Percy out of Tartarus. I tried calling out to her but if she could hear me she didn't show it.

She then placed Percy down inside a cave. Then she used her knife to quickly and skilfully collapse the entrance of the cave. He'd be safe there I'm sure. After a moment she looked up saw me and then the army and her face showed complete disbelief.

She started sprinting towards the base of Olympus to fight with us and I ordered some Skeleton Warriors to give her some cover fire. They started firing at any monsters chasing her trying to distract and kill any monster who could give her trouble. Unfortunately it wasn't enough and she was blocked off from us unable to reach us in time. She fought valiantly but was disarmed by the Venti sneaking up on her from behind.

That's when they all flashed in.

Zeus P.O.V.

I'm Zeus, god of Lightning and King of Olympus. However powerful I am right now, I'm scared. The Olympians and I were in the throne room of Olympus watching the current war restlessly. With the Ancient rules forbidding us from interfering with the lives of the mortals, there was really nothing we could do without being greatly punished.

So we could only watch until something significant happens, i.e. them closing the Doors of Death. Then and only then, were us gods allowed to legally help in the fight. So for now, all we could do is watch, and we did not like what we saw.

We saw an army with numbers in the 100,000's facing off against the seven demigods of the Great Prophecy alongside Nico, the Death spawn.

"We cannot just sit back and watch brother. We must go to their aid immediately." Poseidon roared. I flinched ever so slightly at his harsh tone.

"I agree Poseidon, but we cannot risk breaking the Ancient Laws." Apollo argued back, surprising everyone by just how serious his tone was.

Then my daughter Athena spoke up. "Father, Poseidon and Apollo are both right we must make a wise decision and we must make it now."

"Then what do you suggest, my daughter." I asked rather hesitantly.

After a moment of thought she answered my question. "I believe we should act now. If they lose this fight then we are all done for."

I thought deeply about it, considering my two options. It seemed obvious that they would not close the Doors of Death as no god or goddess not an Olympian has come to their rescue. They could abide by the Ancient Laws and risk everything on them closing the Doors. Or on the other hand, I could break these Laws and rush to their aid risking a great punishment on everyone.

I was still unsure about my decision when Poseidon gasped. Looking back up at the screen I saw the sea surrounding the base of Mount Olympus rise. They then surged towards the Doors of Death at such speed and ferocity it could've only been my brother.

"Poseidon, lower the sea now. I now you think we must act now, but I have not given order yet. So until I give ord-" Zeus bellowed before being rather hastily interrupted by the god in question.

"Zeus, stop. This isn't me brother, I swear on the River Styx." Thunder rumbled outside. "So that means it could only be…" he trailed off.

"Perseus." I muttered. After a moment more of thinking, I had come to my decision. "Everyone, get into battle armour now. It's time to fight for ourselves alongside our Sons and Daughters."

"Shall I collect my Hunters father?" Artemis asked me.

"Yes Artemis. Grab your Hunters. Any other help we can get will be needed. Now off with you all." I called before flashing out to Olympus, the Original Olympus in Greece. Home.
