Chapter 1: An Unexpected Arrival

Authors note:

Disclaimer: I do not own the rights to characters or plot of Percy Jackson and the Olympians. Those belong to Rick Riordan.

Let's make some things clear, I am well aware that a lot of people won't read any of this, but I would like to apologise in advance for not only writing something so unoriginal but also with a story that is bound to get really complicated as I plan to bring in many versions of characters (mainly Percy and Annabeth) from different books. I would also like to apologise for any inconsistencies in relation to the book such as using British English even though most of the characters are American, I will do my best to use American words and spellings. Finally, this story is set when the books were released, specifically the point when the bolt was stolen, (2004-09/10) but I will include media, games and more from beyond that(2011-present) to try and make the story feel more relevant.

No one's POV

Poseidon was bored, this Winter Solstice was going by much slower than he wanted it to. His annoying younger brother was going on about some matters that Poseidon couldn't care less about. He locked eyes with Hestia and Hades and proceeded to mime falling asleep which received two snickering deities in response.

He hoped that Chiron would arrive soon with the children from Camp Half-blood if only so it would put an end to Zeus' righteous monologuing. Speaking of children, his thoughts drifted to that of his twelve-year-old son, Percy. Poseidon wished that he could meet him properly, alas it was a dangerous time to be a son of the Big Three. The children of Kronos, bar Zeus and Hera, had discussed the matter of the Great Prophecy recently, believing it to be upon them and Poseidon refused to bring Percy into the thick of it until absolutely necessary.

His train of thought was interrupted however by the arrival of Chiron and his students led by that 19-year-old son of Hermes, Luke he believed his name was. He was closely followed by a girl who could only be Athena's daughter, the honey blond hair, the startling grey eyes, the way she stood up straight and proud. They were practically the same.

They all came to centre of the thrones and proceeded to bow as one, like it had been rehearsed, it probably had. Chiron was just about to thank the Gods for allowing them on Olympus, but he was interrupted by a bright flash of light that even the Gods had to avert the eyes from.

When the light died down and everyone could see again, those that were already in the throne room noticed three very bewildered groups of people, two groups were mostly teenagers, the larger of the two mainly wearing orange t-shirts and standing amongst them was a very familiar centaur as well as a woman that Poseidon believed he would never be able to see again in person. They all looked rather sad and quite a few were holding back tears, even Chiron and Sally.

The other group of teenagers were all wearing purple t-shirts and were led by a girl who wore golden armour as well as a toga and a purple cape. The signs of a Praetor. They all looked exhausted, and some were covered in small cuts and bruises like they had just fought a battle.

The final group were the most recognisable but also the most shocking as most of them should be dead except one. An insufferable man who most believed didn't deserve the rewards he received. None more so than Artemis and Poseidon. Alas, even Zeus grew tired of him and sent him off to guard the Ancient Lands for eternity.

Zeus finally came out of his stupor, unfortunately he did so rather loudly and rather angrily, "HOW DARE YOU INTERRUPT THIS COUNCIL MEETING, HOW DARE YOU ENTER OLYMPUS WITHOUT PERMISSION!". This caused many of the children to cower in fear as his voice resonated throughout the chamber.

Before he could go any further, another flash occurred only to reveal the Sisters of Fate in its place. The room went dead silent, many dared not breath for fear of the Fate's attention. And then they spoke in a unified raspy tone, "We have brought these heroes from the future so that they may hear of their friend's adventures, we brought the heroes of old from the past so that that they can see what a true hero looks like and we wish to show the Gods of the present what is to come in the next few years and how one boy is critical to Olympus' success in the face of a world-ending prophecy. We wish that Amphitrite, Triton, Persephone and the Hunters are also present to hear of this hero's great deeds."

Poseidon, Hades and Artemis flashed away and when they returned, the aforementioned people were all present.

"Thank you," the Fate's continued. "Time is frozen outside of Olympus so it will remain 21st December until you are finished reading all the books. Everyone except the gods will introduce themselves with their full titles starting with the Greek demigods from 2004."

And with that the introductions started:

"Chiron, immortal trainer of heroes."

"Luke Castellan, son of Hermes" bitterness somewhat present in his voice.

"Annabeth Chase, daughter of Athena."

"Clarisse La Rue, daughter of Ares."

"Travis and Connor Stoll, sons of Hermes."

"Katie Gardener, daughter of Demeter."

"Charles Beckendorf, son of Hephaestus."

"Silena Beauregard, daughter of Aphrodite."

"Castor and Pollux (their surnames are never mentioned), twin sons of Dionysus."

"Lee Fletcher, son of Apollo."

"Michael Yew, son of Apollo."

"Jake Mason, son of Hephaestus."

"Malcolm Pace, son of Athena."

"Chris Rodriguez, undetermined." He said sadly

Hermes' head shot up suddenly, he snapped his fingers. A caduceus appeared above his head claiming him as a son of Hermes. He started to apologise profusely to Chris about not claiming him sooner as he has been extremely busy recently what with Christmas just around the corner. All of this made Luke scowl even deeper.

The last person introduced themselves, "Grover Underwood, Satyr protector"

Zeus narrowed his eyes at Grover causing him to gulp and avert his eyes.

"Next the Roman demigods of 2010" the Fates rasped sparking murmurs amongst the present Greek demigods that weren't aware that Roman demigods existed. Similar murmurs were breaking out between the Gods about the presence of both Greeks and Romans in the same room. The heroes of old bar Hercules were wondering what a Roman is.

"Reyna Avila Ramírez-Arellano, daughter of Bellona and Praetor of the Twelfth Legion."

"Hazel Levesque, daughter of Pluto, defeater of Alcyoneus, rescuer of Thanatos and centurion of the Fifth Cohort of Camp Jupiter."

This introduction made Hades have a coughing fit as the last time he checked, Hazel was standing in the Fields of Asphodel. Nico suddenly became very interested on the dirt on shoes in hopes that she wouldn't see him just yet.

Zeus turned to Hades and was about to yell at him for breaking the oath, but Hades spoke first, "She was born before the oath Zeus so don't get your toga in a twist, I don't even know how she is here."

"Frank Zhang, son of Mars, descendant of Neptune, rescuer of Thanatos and Centurion of the Fifth Cohort." This caused Ares to sit straight up in his throne and actually pay attention.

"Dakota (surname not mentioned), son of Bacchus and Centurion of the Fifth Cohort," he proceeded to take swig of Kool-Aid.

"Gwendolyn (same reason), daughter of Venus and former Centurion of the Fifth Cohort."

"Larry Goldstein, son of Mercury and Centurion of the Third Cohort."

"Felix White, son of Fortuna and Centurion of the Fourth Cohort."

"The Greeks from 2010 will go next."

"Chiron, trainer of heroes."

"Annabeth Chase, daughter of Athena, Head Counsellor of Cabin Six, retriever of Zeus' master bolt, sailor of the Sea of Monsters, traverser of the Labyrinth, bearer of the sky, architect of Olympus and Hero of Olympus." This gained many stares and young Annabeth (now known as Annabeth to avoid confusion) almost fainted from shock.

"Grover Underwood, satyr, finder of the lost God Pan and Lord of the wild." Mini Grover actually did faint from shock and Hermes looked hopeful.

"Travis and Connor Stoll, sons of Hermes, joint Head Counsellors of Cabin Eleven and pranking Extraordinaires."

"Clarisse La Rue, daughter of Ares, Head Counsellor of Cabin Five, sailor of the Sea of Monsters and slayer of the Lydian Drakon."

"Chris Rodriguez, son of Hermes."

"Katie Gardener, daughter of Demeter, Head Counsellor of Cabin Four."

"Will Solace, son of Apollo, Head Counsellor of Cabin Seven and head healer."

"Malcolm Pace, son of Athena."

"Jake Mason, son of Hephaestus."

"Leo Valdez, son of Hephaestus, Head Counsellor of Cabin Nine and fire user." He then lit his hand on fire to prove his point which earned him many gasps and Frank took a small step back.

"Piper Mclean, daughter of Aphrodite, Head Counsellor of Cabin Ten and charm speaker."

"Don't freak out but I'm Nico Di Angelo, son of Hades and Ghost King." Zeus sat down even though he wanted to blast the boy to pieces. He didn't have much time to ponder it however because the next person that introduced themselves had his eyes popping out of his head and Hera scowled.

"Thalia Grace, daughter of Zeus and Lieutenant of the Hunters of Artemis." This earned many gasps from those from the present. The silence was broken by Annabeth running over to hug Thalia and crying into her shirt.

Thalia hugged Annabeth back tightly and whispered soothing messages into her ear.

When Annabeth's tear-stained face emerged, she asked Thalia how she was back. She simply responded by saying that a friend of hers retrieved a magical item that brought her back. This caught Luke's interest as a plan started forming in his mind about getting Thalia on his side, if he succeeded, what he believed to be fairly easy, then Kronos would be unstoppable.

The last demigod of the group stepped forward, "Jason Grace, son of Jupiter and Praetor of the Twelfth Legion."

The Romans gasped as they had finally found Jason after eight long months. They held out hope and the Gods had answered their prayers in a way. They all quickly went back to staring at the throne room in awe. None of them having been to Olympus before.

"And finally, the mortals if you please."

"Rachel Elizabeth Dare, Oracle of Delphi."

"YES!" Apollo exclaimed and started dancing until Artemis pulled him back to his throne by his ear.

"Frederick Chase, Annabeth's father and this is my wife Helen and our children Matthew and Bobby."

Athena looked on mildly interested whilst the Chases received stony gazes from Annabeth and Luke. Annabeth went over to her mortal family and gave each of them a hug, receiving encouraging words from the two adults and reassuring her brothers that they hadn't given up searching for Percy.

Speaking of which, "Sally Jackson, clear sighted mortal and mother of Percy Jackson."

Annabeth then moved over to embrace her in a warm hug as they both tried to hold back tears. Sally did her best to console Annabeth and it worked to some extent.

This interaction received surprised looks from Chiron, Grover (mini Grover) and Annabeth. The first two wondering how they would even know each other that well and the latter wondering who this woman was.

(Long story slightly shorter, the old heroes consist of Theseus, Perseus, Jason, Achilles, Odysseus and Hercules. Hercules is from 2004, so he is a minor God, but the rest are from Ancient Greece.)

"Well, should we start reading?" Athena questioned "This is probably going to take a while."

"Of course mother." Annabeth replied as she went over to pick up the book only to nearly drop it as if it caused her pain. Thalia went over to see what caused the reaction and audibly gasped as her eyes went wide. She took the book from Annabeth's vice-like grip and read out in a disbelieving voice, "Percy Jackson and the Olympians: The Lightning Thief."

AN: And that's the first chapter done. I'd like to make some things clear. I'll probably be horrible at uploading this story so I'm really sorry if that annoys some people.

Percy is going to be quite overpowered in this but not in a way that makes absolutely zero sense. He is also going to be quite intelligent, mostly in tactics and street-smart stuff but some academic things as well. Hercules is going to be an egotistical moron, but Jason isn't because I don't think that's how is character would act.

Thank you for reading.
