Hey everyone, this idea has been on my mind for a while now so I decided to write it. Most stories I see are about Percy going to Eragon's world, well I wanted it to be the other way around. I hope you enjoy. Disclaimer: I own nothing, it belongs to their respective owners
SET AFTER THE EVENTS OF HEROS OF OLYMPUS SERIES.

ALSO! I have another story, The Darkness Rises, an inheritance cycle fanfiction, not a crossover. Please check that out, prologue to chapter 2 are not written as well as 3,4 and 5. That is because there was a major gap before I updated again and in that time my writing improved a lot. But it would be great if you checked that out.

Summary: Galbatorix has won, even in death he gained a victory. Eragon and Saphira are transported from Alagaesia and arrive in another world. How will they cope? Danger lurks on the horizon and Eragon must help deal with a threat beyond anything he has had to deal with before while also trying to make it back home...or will home find a way to him?

This is an extract from a chapter in Inheritance, I added it in so you can see the change from the original book and the little bit I added for my story.

Two things happened at once, then. Elva let out a shriek and fainted and Galbatorix shouted, "Waíse néiat!" Be not. Eragon had no time for words. Again drawing upon the Eldunarí, he cast a spell to drag himself, Saphira, Arya, Elva, Thorn, Murtagh, and the two children on the dais over to the block of stone where Nasuada was chained. And he also cast a spell to stop or deflect whatever might harm them. They were only half way to the block when Galbatorix vanished in a flash of light brighter than the sun. Then all went black and silent as Eragon's protective spell took effect.

Eragon P.O.V

Two things happened at once, then. Elva let out a shriek and fainted and Galbatorix shouted "Waíse néiat!" Be not. Eragon had no time to react as the king launched himself at Eragon and gripped him in a tight embrace to prevent him from moving. The others were about to move in and help when Galbatorix started to glow and get brighter and brighter by the second. The Eldunarí lent their strength to Arya who cast a protective spell over the group in case they were to somehow be harmed. Eragon struggled to get out of Galbatorix's iron grip but to no avail. Galbatorix whispered some words in the ancient language that Eragon could not make out but the king managed a weak laugh as he whispered in Eragon's ear.

"If I go, you're coming with me" and then the king vanished in a flash of light brighter than the sun. Eragon didn't have time to think of a single thought as his body was blasted away by the explosion and everything went dark.

Blackness was all that surrounded him, his body floated in the pitch black darkness that was around him. Was he dead? Was he just dreaming? He did not know. Soon a patch of earth appeared under his feet. A figure walked out of the darkness and into the patch of earth that Eragon was standing on, it was Galbatorix. Eragon quickly drew his sword and pointed it at the king, the mad king just laughed.

"I am already dead Eragon, you cannot do anything to me even if you tried" Galbatorix taunted, Eragon's eyes widened.

"Am I dead?" the blue Rider asked, Galbatorix's face contorted in disgust.

"No unfortunately, but before I pass on to the afterlife I just wanted to let you know, I have won" the king sneered, he gave the king a questioning gaze.

"I cast a spell in the final moments of my life, if I have to leave Alagaësia forever than so shall you and your wretched dragon. I made sure that the release of magical energy from my death would transport you and Saphira to somewhere that you will never return from. Even in death I still win Eragon, you could never have beaten me!" Galbatorix mocked. Eragon was furious and lunged at the king with Brisingr and made to decapitate Galbatorix but as the sword made contact, his body dissolved into smoke and he was gone.

He refused to believe Galbatorix's words but somehow, he knew that he wasn't lying to him. The thought of Angela's prophecy comes to his head 'Your fate will be to leave this land forever. Where you will end up I know not but you will never again stand in Alagaësia. This is inescapable. It will come to pass even if you try to avoid it…' never before had those words impacted him like they did now. He curled up into a ball and began to cry softly, feeling like a young boy again. What if he would never see his friends again? Arya, Nasuada, Orik and Angela, has his fate finally come? Will he never return to Alagaësia, had he seen them all one last time in the throne room? These thoughts ran through his mind as he cried.

But he remember that Galbatorix said that Saphira would be transported with him, so where was she? He could feel her, she was so close but so far away, he pondered on why this was. After hours of thinking he came up with an answer, he is dreaming. But that would not make sense, if he is dreaming then does that mean everything that happened was false, not true? He hoped so but at the same time he felt like did happen and that it was not just a dream. Light started to appear all around him and he was blinded by it. He knew that now it was time wake up and discover the truth.

Eragon opened his eyes with a groan, his vision was blurry and his body ached in pain. Soon his vision cleared up and he found himself on some beach with Saphira by his side who was also waking up.

"Where are we?" he asked as he looked around, a forest was behind him, nothing looked familiar. He started to panic as he realized that everything Galbatorix had said was true, he was no longer in his home land.

He looked at Saphira and saw she was slightly shaking as she too realized that they were not where they were meant to be.

'He didn't lie…' She said and he knew that Galbatorix had appeared and talked to her as well. He went over and placed his hand on her neck for comfort.

'It's okay Saphira, we are alive and we can work this out and get through this' he said weakly, half of him did not believe those words and it showed across their connection. Saphira looked at him before standing up and heading towards the edge of the forest.

'We cannot give up hope yet, Galbatorix has not defeated us yet! We can make it back!' She said, determination and hope pouring through their link, it surprised Eragon that she still had this much determination in her. It boosted Eragon's hope and he vowed to himself that he would not stop until he and Saphira made it back home.

He took a step towards the forest, what could be in there? He didn't know. This place looked peaceful enough but he wouldn't let that fool him, who knows of what kinds of evil things that might lurk in that forest.

'I am going to go in the forest and have a look around, you stay here at the beach and I will be back in a few hours and I need your help I will call for you but I should be fine' he said, the blue dragoness sent him a sceptical look.

'And why should I stay here?' Saphira asked.

'Who knows what dangers lurk in the forest, I don't want you to get hurt' Eragon replied, she snorted and shook her head slightly.

'If anything you would be the one to get hurt, but I shall stay here but I swear, if you are so much as attacked, I am going to strap you in the saddle so you can't go wondering off without me ever again!' She warned, he smiled at her and then started to walk into the forest.

He had only walked for a few minutes and already he was amazed at how different the trees and plants were compared to the ones in Alagaësia. It was incredible, so far he had not seen anything out of the ordinary that might be dangerous. He walked for a bit longer until he got to a creek, he noticed a blue flag standing in the mist of some trees. It intrigued him and he approached it. He stood before it, it looked like nothing special but it was strange that it was standing out in the open like this with nothing much else around. Eragon reached out to touch the flag when he heard a voice from behind him.

"Who are you?!" the male voice said, Eragon span around as quickly as he could and drew Brisingr, the blue blade gleaming in the sunlight. The male wore a strange bronze looking amour, his eyes widened in surprise and awe of the blade and Eragon himself and he produced a small object, he clicked a button and it grew into a sword. Eragon was surprised and shocked at the weapon and took a second to admire the blade the man held. After a few seconds of staring at each other, he did not know whether to attack or not, but he soon came to the conclusion that Galbatorix sent him here and that anything and anyone could be dangerous and working for him. And so Eragon launched forward to attack his opponent.

Percy P.O.V

Percy had been tasked to guard the flag for today's game of capture the flag. The teams were Poseidon, Athena, Apollo and Ares cabins versus Dionysus, Demeter, Aphrodite, Hermes and Hephaestus cabins. He didn't really pay attention to the battle plans at all, all he had to do was guard the flag, simple. He would be the only one guarding the flag for this game though. As the game began, everyone charged until out of sight. It was pretty quiet for the most part of the game, all he did was hide and wait for people to come and try to grab the flag, but no one did though. Most likely kept busy by the Athena and Ares cabins no doubt.

After sitting in the bushes hiding for ages, he saw something at the creek. A strange man was there casually walking along the creek and then he noticed the flag that Percy was guarding. He gave a questionable look and walked towards the flag. Percy didn't get a good look at the man but judging from his armour and clothes, he was not from around here and was definitely involved in a battle recently. Percy crept out of his hiding spot and walked up behind the strange man.

"Who are you?!" Percy called out, the man turned around so fast and drew a blue blade within a matter of a second.

Percy got a good look at the man now, he was average height but his build was incredible, he was ripped and lean. But what got Percy the most was his facial features, they were almost cat like and his ears were pointed, he had never seen anything or anyone like him before. His blue blade was the most beautiful sword Percy had ever seen, absolutely no flaws at all, the blade also had a gem in the hilt, he wasn't sure what that was for, the last thing Percy noticed was a strange marking etched onto the blade. He had one question about the blade, what was it made out of? Percy pulled out his pen and withdrew Riptide, as it grew into a sword he saw the man's surprise that the weapon had just appeared.

After a few seconds of just staring at each other with swords drawn, Percy began to feel power radiate off of this man but it wasn't normal, it was a different kind of power. Suddenly the man launched at Percy with incredible speed that it startled him. Percy was able to block the strike to his chest and jumped backwards to avoid being stabbed. He rushed forward and swung his sword at the man's side, but he blocked it with relative ease, again and again Percy lashed out with attacks only to have them blocked.

The man decided it was time to go on the offensive, quicker than Percy thought was possible to move, he unleashed a series of complex moves and most of them found their mark on Percy's armour. He staggered backwards after the fast and violent assault but fortunately none of the attacks had been able to draw any blood.

Percy charged as fast as he could with his sword raised and quickly brought it down only to slam against the blue sword, the impact sent a small shockwave through the air. With their swords locked together, he tried to push the man backwards but he would not budge. 'Damn he is strong!' Percy thought to himself. Percy freed his sword quickly slashed at the man's arm to his surprise, it met its mark. Blood began to flow down the man's arm but that only served to make him fight harder than before.

Their swords clashed once more but Percy felt his leg kick him in the gut and send him flying into the creek. Instantly Percy felt his power return to him, he stood up in the creek and grinned. He summoned powerful jets of water at the man who was blasted backwards in the air with a look of pure confusion on his face. Percy also summoned a personal hurricane to surround him, as the man got back onto his feet his jaw dropped at the sight of the hurricane roaring around Percy.

"Impossible!" The man said and Percy could only grin.

Soon everyone from Camp Half-blood appeared at the source of commotion that Percy and this man had caused. They were shocked to see the sight before them, especially the man that stood before Percy, for his looks and his sword, everything about him was different. As the man began to look at all the people that surrounded him, Percy used this moment of distraction to charge straight at him, the man only just saw this at the last second and raised his palm that had a strange scare, symbol on it.

"Letta!" the man shouted, Percy had no idea what he had just said but the man's palm glowed and then suddenly Percy was unable to move, he was stuck in mid-air and his hurricane faded also.

"I can't move!" Percy shouted in frustration, though he was stuck, he summoned a sphere of water around the man and started to drown him. As he did this he felt the strange power that had kept him still stop and he was able to move again. Chiron shouted at Percy.

"Stop this at once Percy! You are going to kill him!" Chiron shouted at him.

Percy was about to stop when the sphere of water exploded outward in all directions. The man's palm glowed again like it did before. He quickly got up to face Percy but staggered slightly, Percy could see that he was exhausted from fighting or maybe it was from something else. Percy raised his hands as a sign of peace and slowly took a step forward.

"If you are quite done trying to fight me, maybe you could settle down and tell me your name" Percy said, as he said this the man narrowed his eyes in suspicion.

"Are you in league with Galbatorix?" the man asked, this only confused everyone who was watching the scene unfold before them. Chiron walked forward towards the man, the man's eyes widened in disbelief and shock that Chiron was half horse.

"We know not who this Galbatorix is, please, let us put our weapons away and talk things over" Chiron suggested. The man looked away and appeared to be in deep thought and didn't say anything for a few minutes. He soon looked back to answer.

"Very well, but I swear if you are lying to me, I shall kill you were you stand. Let us talk and for the record, my name is Eragon Shadeslayer"

There we go, hope you liked it. Battle scenes are hard to write, that is going to be my goal, to improve and write even better fight scenes. Please leave some feedback and I will see you all at the next chapter
