Zoha Ven:*bows down low* I'm so sorry! I have plans for this story, it's just that I have loving readers on my other stories, and I can't keep them waiting too! Thanks for your review. I better update soon... I like to spoil readers in this particular story with long chapters and cliffhangers... *gives out cookies* Thing is, I've been working on other stories and all that. And then school... *shudders* then just sleeping and watching anime. Don't worry, I'll update soon... hopefully.

AnimeandDragonfan54: Gods, how many of my stories do you like? How many fandoms do you know? Seriously! But I'm not complaining or anything. Thanks for your review.

And for the length of the story... Well, sadly I cannot make it too long, or it'll be too late to stop Gaia. Maybe it's going to be about 15 chapters or a bit less or a bit more.


HICCUP

Everyone knew that Astrid Hofferson was never evil. Well, she could be, well, 'evil', but not Dagur evil. Or Alvin evil. Or Dragon Hunter evil, and definitely not Drago evil. But she was acting very evil right now.

Hiccup knew her eyes were cerulean blue. He'd joke about that at times, until right up to the part where his girlfriend slugged him on the shoulder. But this time her eyes were flashing gold, like treasure, or those weird round metal things Trader Johann sometimes brought and called them 'coins.'

Hiccup knew that there was something definitely wrong. Percy took out his ballpoint pen, and took off the... what did he call it? Oh yeah - a pen cap - and it morphed into a deadly glowing bronze sword. Astrid hissed in a way that wasn't like Astrid at all.

"Demigod," she hissed, as Annabeth brought out her sword. "One puny Celestial bronze sword cannot beat me. Neither can that sword made of drakon bone."

Hiccup stifled a gasp. How did Astrid about Percy and Annabeth being demigods? He hadn't told anyone! He'd swore on the River Styx! But Astrid didn't sound like Astrid. It felt like someone - or something - was controlling her underneath. He looked desperately at Percy, while at the same time activated his flaming sword and did the Night Fury call. "I didn't-"

"I know," Percy replied. "Your girlfriend - she's being controlled by an eidolon."

"Possessing spirit," explained Annabeth when she noticed Hiccup's confused face. "Servants of Gaia. They possessed Percy, Jason and Leo once."

"Don't remind me," said Percy, his face turning into a grimace, as if he was remembering something awful.

"Two little demigods - and a mortal," mused Astrid/eidolon, holding her battleaxe. "Your mortal iron cannot hurt me, mortal Viking. As for the demigods... why, Perseus Jackson and Annabeth Chase, it's been a while! A little bit of me regrets killing you... alas, two demigods alone and one mortal cannot defeat me."

Perseus, recalled Hiccup. That Earth Mother called Percy Perseus. So did the ei...eidolon.

"Then come at us!" yelled a voice from behind, which was most definitely Leo's. "You've got some mortal iron there, haven't you? Well then, eat Celestial bronze and Imperial gold!"

Toothless raced out at front, and growled, but was immediately confused after seeing Astrid. He looked at Hiccup, his eyes asking, Who's the baddy-baddy here?

"Astrid's evil, bud," breathed Hiccup. "Well, do a few warning shots, Toothless, but don't kill her!"

Toothless obeyed his rider, while everyone else surrounded Astrid, with weapons close by. Valka went by her son's side. "What is it, son? I heard..."

"Um, fight first, ask questions later?" yelled Frank, aiming an arrow at Astrid, but luckily not shooting her.

"Fools," spat Astrid. "You think I am the only one of my kind here on this mortal heap of rocks?"

Hiccup gulped. "What in the Nine Worlds, there are more?"

"Last I remembered, there were only three!" yelped Hazel.

Moments later, Snotlout appeared, with a mace in one hand and a dagger in the other. The twins appeared, looking ready to kill. Then Silent Sven and a few other Vikings appeared. Like Astrid, oh gods... they all had gold flashing eyes, twinkling in the sunlight.

No-one messes with my people without being given a piece of my mind, thought Hiccup angrily. Now, what would Dad do? Hey Dad, guess what? Nice up there in Valhalla? Well, I just found out there are demigods and Greek and Roman gods and oaths on rivers and evil possessive spirits that have brainwashed Astrid, Snotlout, the twins, and other people. What would you do? Oh that's right - you didn't have to deal with this Greek and Roman nonsense when you were alive, did you?

"Piper can talk them out!" Jason yelled. "Piper, do your thing!"

"What thing?" asked Valka.

"Well, it's a long story..." said Frank wavering off. "But we will sort things out later, but for now we better make Piper do her thing. Don't listen to her - pinch your arms or something when she starts speaking!"

"Eidolons," Piper said firmly. "Listen to me."

"We would never-" snarled Sven in a very not-so-Sven way, then stopped. All the eidolons turned to her. Piper took a deep breath and, with Katoptris trembling in her hands, said, "Gaia sent you here, did she not? Why are there more of you?"

"Our mistress was most displeased," hissed Tuffnut, "you made us swear on the Styx not to harm any of your crew."

"The mortals are not one of your crew," growled Ruffnut, "so we could use them. You did not make us swear on the Styx Gaia sent more of us from Tartarus to help. Their brains were easy to brainwash - especially when they had no idea of our existence."

"Your Astrid was very untrusting of you," whispered Astrid, "so she gave in to Gaia."

"Impossible!" yelled Jason. "Your mistress Queen Dirt Face misled her!"

"What is Astrid talking about?" asked Valka, bewildered, gripping her staff tighter. "And why are some Vikings have gold eyes and why do they look... possessed?"

"Questions later!" yelled Leo, waving a celestial bronze hammer at the possessed Vikings.

"Leave the bodies," ordered Piper.

"No," all the eidolons answered in unison.

"You will leave them," ordered Piper, like a mother who was losing her patience. Hiccup felt scared. Well, he'd thought that he was only scared of people who wanted to kill Toothless or any other dragons or people who wanted to bring down Berk, like Drago, for instance. "Leave them."

"Leave them," said the eidolons, and Hiccup suspected a dreamy tone in their voices.

"Swear on the River Styx never to possess anyone here on Berk, or any dragon or creature that resides here."

"We swear on the River Styx."

"Now go!"

Suddenly, Hiccup felt as if a darkness was disappearing, a curse lifting up from a kingdom. The cold shivers Hiccup had experienced were gone. Then all the Vikings slumped.

Hiccup caught Astrid, and Jason and Piper got the twins. Everyone else got the remaining Vikings, except for Snotlout, who fell to the ground without anyone bothering to catch him.

"Mom, bring them all to Gothi, and when you come back, I'll explain everything," ordered Hiccup. "Frank, Hazel, Leo..."

"On it," the three demigods nodded in unison. Valka nodded, but she looked confused and worried; Hiccup didn't blame his - this world of Greek and Roman gods and monsters... and to think about it, he was scared of the stories about the Norse gods! He'd always been terrified of Ragnarok, the Day of Doom. Well, he'd never seen the Norse stories for real... Besides, if what the demigods had said were right, then if they were too late to stop her, Gaia, the Earth Mother, would fully awake, and it would be the Day of Doom. Everyone would die.

Leo, Hazel, Frank and Valka took some Vikings and left for Gothi. Frank looked relieved he did not have to turn into a dragon.

"Well," said Percy. "That was... refreshing."

Hiccup panted. "I think you'll have to tell my mother..." He placed Astrid down gently.

"Well, your mom deserves to know," replied Annabeth. "And Astrid... she was untrusting of us."

"Yippee, now there'll be three mortals who'll know about us," said Jason.

"Well, I guess my mom does need to know," replied Hiccup. "I mean, when Percy and Annabeth have gone to bed, she keeps on asking me questions. If I'm keeping secrets from her. If I know stuff that she doesn't know. And Astrid... she was so untrusting of you. Maybe if you told her who you guys were, she'd lay off you guys."

"Agreed," said Percy.

Then there was silence. Percy, Annabeth, Piper and Jason hung their heads. Was that... guilt?

"Guys?" asked Hiccup, looking at the four. "What's wrong?"

Annabeth spoke up. "We're sorry."

"What?" spluttered Hiccup. "What the Helheim are you sorry for? It wasn't your fault that the eidolons possessed Astrid. Was it? What's wrong? Why are you sorry?"

"Well, the thing is..." Percy began.

"We're sorry for bringing all these things to Berk," finished Jason.

The words stabbed Hiccup like a dagger.

"What?" he asked slowly.

"Well, technically, it was our fault that the monsters are here," said Piper. "Gaia must've sent the Earthborn to attack us. The eidolons must've been sent by Gaia as well. We're putting you in danger. And time is running out. We have to leave soon."

Toothless purred. Hiccup felt sad that his new friends were going to leave soon - part of him had hoped they were going to stay here on the Isle of Berk. He'd forgotten the Argo II. He didn't want them to go.

"Hey, Hiccup," grinned Percy, as if he'd read the young Chief's thoughts. "Don't worry. We'll see you again... I hope, as long as we're alive still. Soon, we'll teach you something called Iris-messaging."

"Iris-messaging?" asked Hiccup curiously.

"It's how demigods and gods use to contact others," explained Piper gently. "We'll give you a bag of drachmas - Greek coins - to help you contact us. Hopefully, it'll work for you. Probably."

Hiccup nodded, and slowly, he picked up Astrid. He was never a strong man in his tribe - but he managed. "I'll take her to bed," said Hiccup. "Go look for the others."

The demigods nodded, and Hiccup went towards the Chief's Hut. Today was eventful, thought Hiccup.


LEO

Mucus Man - well, Snotlout - was freaking heavy.

Like, seriously. Leo dragged him for part of the way, and he was only a few metres away from Hiccup's house and he was already sweating like crazy. Leo, luckily, was able to steal a cart and put Snotlout on it (he wrote a small message on a Post-it note from his magic tool belt - IOU one wagon- from: ALL DA LADIES LUV LEO and stuck it on the back of the unaware owner of the cart). He got Frank, Hazel and Valka to put the Vikings on the wagon, and to help Leo push.

Jeez. Maybe scrawny ISN'T the new hot, thought Leo, who wiped the sweat off his forehead.

"This is easy," said Frank.

"Easy for you to say," grumbled Leo. "I'd rather spy on Hiccup and Astrid and sing 'Love is in the Air.'"

Hazel frowned. "What's that?"

"Never mind," said Leo, while Frank smiled.

Valka sighed, and watched the other Vikings go along. "I do know there's something Hiccup's keeping from me, and I have a feeling that it's about you."

The three demigods all looked interested in their shoes. Finally Hazel spoke up. "Well, we told Hiccup something. A secret. He swore not to tell unless we gave him permission."

"And that is...?" Hiccup's mother began to ask, but her voice began to waver off.

"We'll wait for when we get back," panted Leo, as he watched Frank push without effort.

Gods, why wouldn't his godly dad Hephaestus give him a growth spurt? Or rippled muscles? Or at least a six-pack. He grunted. Gothi, thank the Olympians, was close, but they still had to push.


PERCY

Percy realised he still had Riptide as a sword, so he picked up the pen cap from the ground, and placed it on the tip of the blade. Sure enough, the bronze sword morphed back into a pen. No point making a scabbard. They were going to confess about them being demigods to another two mortals.

Piper took a deep breath and said, "Gaia managed to possess mortals. Oh gods, I mean, I know she can do it anyway, but still, it's scary."

Annabeth nodded. "Yeah. Gaia's stopping at nothing to kill us. Or to get two of us for the blood of Olympus. So she can fully wake."

Hiccup came to them, and said, "Astrid's awake. Maybe it's best to... you know."

Percy, Piper, Jason and Annabeth nodded. They headed inside the house, Percy first inside. Oh gods, he thought. What is she going to do to us?

He saw Astrid sitting on a bed - the bed Percy had been sleeping on. She had blonde hair like Annabeth, but unlike Annabeth, her hair was braided and she had a half fringe. She had blue eyes like Thalia Grace. She had a fur hoodie, metallic shoulder pads with mini spikes, and large thick bracers covered in fur. She had a red shirt and a skirt with skulls. The skulls and the red colour reminded Percy of Ares, the war god - and it certainly didn't bring back much happy memories. It brought a bad taste to his mouth, like he'd just sucked on something that tasted disgusting. Her axe was by her side.

Percy saw Hiccup walk up to Astrid and whisper something in her ear. Astrid glared at Percy, as if to think, This is all your fault, and brought out her axe and swiped it, narrowly missing Percy's neck.

"Hey!" Annabeth cried indignantly.

"Hmph," said Astrid. "Hiccup, why did you bring them here? They're evil. They-"

"Astrid," Hiccup sighed, "I... haven't been really honest with you."

Astrid raised her eyebrows. "As if I didn't know that, Hiccup. You've been hiding something. It's about them." She pointed at Percy and the other demigods. "They're dangerous. They brought that strange giant thing-"

"Earthborn," corrected Jason.

Astrid glared at him, but continued, "and the weird Voice from the Earth told me I could prove you wrong, and Percy Jackson and his friends wished to destroy the world."

A shiver went down Percy's spine. It was as if Gaia was here, smiling a creepy smile. "Astrid," he said slowly, "was that 'Voice from the Earth'... did it sound sleepy?"

Astrid nodded. "Yes, but why do you want to know?"

Percy ignored the glances from his girlfriend, Piper and Jason. "What happened next?"

Astrid hesitated, but after an encouraging nod from Hiccup, she said, "Well, it was like this. I thought was a dream. The Voice asked me if I wanted to help her, to stop you. I said yes. Then I woke up, and then there was this small earthquake. I felt hot. The Voice said that I wouldn't regret my decision, and she would send one of her - I'm sure it was a her - her servants to help me. Then everything went fuzzy, and black. I don't remember anything else, except that I woke up."

"Astrid, that Voice was Gaia, the Earth Mother," said Jason.

"The Earth Mother?" asked Hiccup and Astrid in unison.

"Yeah," replied Annabeth. "She's evil-"

"No!" Astrid raised her axe at Annabeth's throat. Percy reached for Riptide in his pocket, and closed his hand around it. No... he wouldn't bring it out just yet. But if that Viking even lay a finger at Annabeth or any of his friends... well, Percy would be ready. "You're the ones who are evil! You're working for Drago Bludvist! You're also working for a really powerful enemy! You're lying!"

Hiccup held her back. "No, Astrid! They don't work for anyone evil! They don't work for Drago! They work for no-one!"

Astrid looked at Annabeth with loathing. "Explain." She turned to Hiccup and said, "Do you really believe them, Hiccup?"

Hiccup nodded. "Astrid, it's all complicated. But I promise, I'll explain to you. I promise. We'll just wait for the others to come back."

Astrid looked downright murderous - like Grover had been when he realised that the 'Humane Animal Transport' they were on five years ago was not humane at all. She sat back down on the bed and said nothing.

Hiccup looked at Percy. "I'm sorry," he apologised.

Percy nodded. "It's fine. We'll tell her the truth. When the others get back."

Suddenly, the door opened. Valka came in, followed by Frank, Hazel and Leo.

"Hola, amigos!" Leo waved, a large smirk on his face. "Nice to be back! So, what-" Leo stopped to a halt when he noticed Astrid. "Um..."

Valka looked at her son. "You said you would explain."

Hiccup breathed deeply, and looked at Percy. "Can I...?"

Percy nodded, "I, Percy Jackson, give you permission to tell these two about the truth."

Thunder rumbled outside.

"I thought it was a clear day today," said Astrid.

"Woah," said Leo, "are you going-"

"They deserve the truth."

Leo nodded. "Right."

Hiccup looked at his mother and girlfriend, and said, "They're demigods."

Silence for a few moments and finally, Valka said, "Demigods?"

"Like... the children of Norse gods?" asked Astrid, bewildered.

Hiccup nodded, and Percy began to speak. "Yeah. Except that we're the kids of Greek and Roman gods. A long time ago, there was the Greek civilisation, and then the Romans. They worshipped gods. They had different names, like Zeus for Jupiter, Aphrodite for Venus, but they were still the same beings."

Annabeth continued: "In the old stories, these gods fell in love with mortals - I mean, normal humans. They had children called demigods, or half-bloods. Some of the famous ones are Heracles, or Hercules in Roman form, and Theseus - the one who killed the Minotaur - a half man, half bull."

Valka nodded, though she looked amazed and puzzled at the same time. "These monsters are real? And you're really... children of gods?"

Jason nodded. "Yes. One of our parents were gods, and the other is a mortal."

"Anyways, according to the demigods," Hiccup said, "in modern times, well, the gods still fall in love with mortals and have children."

"Yes, but their lives are very dangerous," said Annabeth. "They have to fight monsters that want to kill them. Some demigods don't even get to reach the age of fifteen."

"That's sad," said Valka.

Piper nodded. "That's why there are camps for demigods. There are two of them - Camp Half-Blood, for the Greek demigods, and Camp Jupiter, for the Roman demigods. They keep the monsters away with magical borders. Camp Half-Blood have necklaces and orange shirts -" Leo, Piper, Annabeth and Percy showed their necklaces - "and Camp Jupiter demigods have special tattoos and purple shirts." Percy held back from showing his tattoo, while Jason, Frank and Hazel pulled back their sleeves and showed them their tattoos - lines for their service in the legion, SPQR and a symbol of their godly parent.

"We go on quests to prove our bravery and other things," explained Frank.

"And defeating this... Gaia has something to do with their quest," finished Hiccup.

"But who is Gaia?" asked Astrid and Valka in unison.

"Well, the Earth Mother, equivalent to that Norse Earth Mother Jörð that you have," said Annabeth. "She's evil. Yeah, I know it's hard to believe, but still. She wants to destroy the world with her sons the giants. We have to stop her."

"Wait," said Hiccup. "This reminds me of something. I had a dream."

Percy and the other demigods looked at him. "Well," said Percy. "We all have weird dreams-"

"This was definitely weird," agreed Hiccup. "I think I was in some room. There was this dead body, that looked like a corpse or a mummy. She spewed green smoke. She said these words: A half-blood of the eldest gods, shall reach sixteen against all odds-"

Percy looked at Hiccup with a jolt, like he'd waken up with a lightning bolt. He knew those words - the last Great Prophecy! Oh gods, how did Hiccup know about it? Annabeth looked at Hiccup the same way. Hiccup looked confused. "What? Why are you guys looking at me like that?"

"Hiccup," Percy said slowly. "Were the next lines: And see the world in endless sleep, the hero's soul, cursed blade shall reap? A single choice shall end his days, Olympus to preserve or raze?"

"Yes," Hiccup said worriedly. "How did you know-"

"Wait," interrupted Annabeth. "Did the Oracle-"

"What's an Oracle?" asked Astrid.

"You know, Oracle. That dead mummy thing is - I mean, was the Oracle, until Rachel Dare took over."

"Who's she?" asked Valka.

"We'll tell you later," said Percy. He turned to Hiccup. "Did the Oracle say anything else?"

Hiccup nodded. "She said, 'Know the present for the future', then she said, Seven half-bloods shall answer the call, to storm or fire the world must fall-"

"An oath to keep with a final breath, and foes bear arms to the Doors of Death," the demigods finished.

"How did you-" began Hiccup.

"Well, those two were prophecies."

"What are prophecies?" asked the Vikings in unison.

"Prophecies... well they're hard to explain, but you can't go on a quest without one," explained Annabeth. "There's a Great Prophecy - like a big prophecy that could change the course of the world. The 'half-blood of the eldest gods' one was the previous Great Prophecy."

"Thanks for reminding me about the war with Kronos," Percy muttered. He remembered the war very clearly - how Kronos had taken Luke Castellan's body, because Luke hated his father Hermes and wanted to tear Olympus down, but had ended up as a hero of Olympus. He remembered all those others who had died - Charles Beckendorf, Silena Beauregard, Michael Yew, Ethan Nakamura, and others who had died during the invasion of Manhattan. It was painful. Not to mention Zoë Nightshade, Bianca di Angelo, Daedalus, Castor, Lee Fletcher, and countless others.

"You said that it was the previous Great Prophecy," noted Valka. "What's the current one?"

"Oh - that one is the 'seven half-bloods shall answer the call' one," replied Percy. "The one that we're having right now, while we're trying to defeat Gaia."

"What do the prophecies mean?" asked Astrid. "They sound confusing."

"Well, prophecies don't come clear until the events come to pass," explained Hazel. "So we're not sure what the lines mean exactly. But we do know the first line: Seven half-bloods shall answer the call. Seven half-bloods, some Greek, some Roman, answer the call to defeat Gaia before she fully wakes."

They all nodded. "Wait, who are your parents?" asked Astrid and Valka and unison.

"The godly side?" asked Percy. "Well, my dad is god of the sea in his Greek form, Poseidon."

"Mine's also Greek; my mom's Athena, goddess of wisdom and battle," said Annabeth.

"My mom's Aphrodite, goddess of love and beauty," said Piper.

"And my dad is Hephaestus - god of blacksmiths and fire - the most SUPERCOOL OLYMPIAN GOD EVER!" Leo yelled, punching his fist in the air.

"Oh, come on, get to the point, Leo, he's not," said Jason gently. "Frank, Hazel and I are the Roman demigods. My dad's Jupiter, king of the gods, god of lightning, thunder, the skies, etc, etc."

"My dad's Mars, the god of war," said Frank.

"And my dad's Pluto, god of the dead, the Underworld and riches," finished Hazel.

Hiccup opened his mouth, as if to ask something, but closed it.

Astrid gaped. "You're lying."

"No, none of us are lying!" said Percy. He remembered Hermes saying to Percy after the war against Kronos: They'll believe anything but the truth. But somehow, all the Vikings could see through the Mist. "I swear on the River Styx!"

Thunder boomed, sealing the deal.

"Why does thunder always boom when you swear on the Styx?" asked Hiccup.

"An oath on the River Styx is the most serious oath you can ever make," explained Annabeth. "Break it... and you can suffer a fate or punishment worse than death. So... you don't break an oath on the Styx. Ever."

The Vikings nodded.

"I'm shocked, but I believe it," said Valka.

"So do I," agreed Astrid. She turned to Hiccup. "The... demigods told you the truth already, didn't they? You swore on the Styx not to tell, didn't you?"

She's smart, thought Percy. She'd be a perfect daughter of Athena.

Hiccup nodded. "Yeah."

"Now you two have to swear on the Styx," said Frank. "Do you swear on the River Styx not to tell anyone about our true identities or our parents or anything demigod-related until we give you permission?"

"We swear," Valka and Astrid said in unison.

Thunder boomed, sealing the deal.

Suddenly, Percy heard a familiar voice in his mind, Yo, boss! Need a handsome horse?

Shut up, Blackjack, Percy thought back. I'm not in the mood to answer you! Where are you? And don't call me boss!

I'm on the roof, boss!

Well, get off, because I don't think the Vikings will be happy.

Say please, boss...

PLEASE! thought Percy angrily. I'll call you when I need you!

Fine, fine, boss, Blackjack answered, and Percy heard faint clip-clops that disappeared. See you later! I'm off to eat somethin'. Don't freak, the horny helmet people haven't seen me yet.

Percy sighed.

"What?" asked Hiccup.

"Oh - nothing," Percy replied quickly.

"So... what do we do now?" asked Piper.

"We go back to normal business, and pretend that the previous stuff never happened?" suggested Leo, building a tower that looked like the Empire State Building out of twigs.

"That, would be a good idea," said Hiccup and Percy in unison.

"Hey," said Hiccup. "The dragon races are tomorrow, do you want to come and see?"


No cliffie!

But... there might be some exciting stuff happening probably next chapter, as well as the Dragon Races.

Please review! See you for Chapter 8!
