First story, so let me know how it is. Originally planned it as a one-shot but if theres interest I will make it into a full story. Thanks!

Jon awoke with a gasp. He blinked his eyes quickly, adjusting to the light coming from a window. When his eyes finally came into focus he looked around the room and realized it was his old room at Winterfell. Looking down at his own body, he realized he was much smaller, there was no excess muscle from training with Longclaw, there were no scars from his brothers at the Night Watch or during the many battles he faced and the main thing that was missing was the giant hole in his chest where the Night King had skewered him with a large ice spear.

That was the last thing he remembered, he rode on Rhaegal as Daenarys rode on Drogon. Together, along with the armies of the North and South they marched on the army of the dead. Wielding dragon glass and fire they fought them on the plains to the east of Winterfell. Jon had watched as Drogon decimated the enemy lines with his fire and as the Dothraki rode down the dead, watched as the Unsullied, in their stiff formations charged them with their spears tipped with dragonglass. But it was not enough. The power of the Night King was too much and his army too great, Jon saw as they swarmed over the Northerners like ants on a hill, killing everything in their path before the dead joined their ranks.

Jon had decided to find the Night King, killing him would end it. He remembered Rhaegal being pierced by three ice spears from the other white walkers as the dragon breathed flames on all those around them. He remembered falling and falling until they impacted the snow covered plains. His right arm had been broken from the landing and he knew a few ribs were aswell but he got up and drew Longclaw and marched towards the Others. He managed to kill two before the Night King marched towards him, with a spear as tall as he was and twice as thick as his blade. They fought, Valyrian steel against ice, the clang of their weapons ringing in the air, but Jon realized he was outmatched, the Night King had thousands of years of practice, while he was a simple bastard, raised at Winterfell, trained only by a master-at-arms at Winterfell and Castle Black.

When the ice spear slashed against his leg, he had collapsed, blood seeping from many cuts across his body into the snow below him. He had looked up into the icy blue eyes of his enemy and closed his eyes in resignation that he had lost, the North had lost, and the world would descend into darkness and death. Jon barely felt the spear as it skewered him, passing through him and lodging in the ground behind him, keeping him in his kneeling position.

As he slowly lost consciousness he thought he heard Dany yelling his name before everything faded to black.

Yet here he lay, in his bed, in Winterfell. He got up and crossed to the window and looked down upon the courtyard. He could see many people running around, yelling about this and that, it was much busier than it normally would be. Thinking hard he thought about what day it could be. Looking at his body he knew he was around 15 or 16. This must be the day King Robert arrives.

Jon sat for nearly an hour, thinking about what he should do. If he did nothing, the Others would win again. He couldn't allow the war to spread through Westeros like wildfire again. And Dany...his aunt, but also his love. He loved her, with all his heart he loved her. Right now she would be in Essos, about to be sold to a Dothraki in a few months. But if he went to get her, first she would never believe him and second...all those slaves. She had suffered, she had told him that much, but she had done a lot of good. And one night while sailing back North from Kings Landing he had asked her, if she had the chance to change anything, if she would. She had shook her head and smiled at him, saying she wouldn't have changed a thing.

So Dany would be left alone, to discover her own path again. But how to stop the war that was coming in Westeros. He ran out of time to think when there was a knock at his door.

"Jon, you need to get ready. The King should be here soon." A voice he recognized as Robb said.

"I'll be down in the courtyard soon." Jon replied, having to keep his voice even after hearing his dead brother once again. Robb had always been like a true brother to him, never looking down on him or making fun of his status.

Dressing quickly in a black leather doublet and covering himself with a thick dark grey cloak he descended to the courtyard to await the king with the rest of his family and servants. Before he left he made sure to have a dagger on him, a sword would be too hard to hide but a dagger wouldn't attract attention. After so many years wearing one, he felt naked without steel at his side.

The King's arrival was the same as he remembered, Robert was as fat as ever, Joffrey was a sadistic bastard and Jon wanted to drive his dagger into Cersei's heart, if she even had one. The feast had begun nearly an hour ago and he could hear the loud laughter and chatter from the Great Hall. Nobody would notice his absence so he had spend the time gathering a few things. He had visited the Library and searched for a book that he now held under his left arm. He also went to the armory and grabbed the best sword he could find which was now strapped to his left hip, opposite his dagger.

Taking a deep breath as he approached the doors leading into the Great Hall he steeled himself. He had decided to act now, to end the war before it could ever begin. What he was about to do could save tens of thousands of lives or it could mean his death. Either way he had to try.

Entering the hall he kept to the shadows as he walked close to the walls. He could see many stark soldiers and lannister men at the tables, drinking and eating. At the head table sat his family and the King's family, behind the King stood three Kingsguard. It was hard to tell who it was since they all wore helmets but Jon assumed at least Ser Barristan Selmy was there.

He was now half way across the hall and approaching the head table, still nobody had noticed his approach, which he thanked the gods for. He drew his dagger slowly and hit it in his hand that was covered by the large book under his left arm. His arm right was still free, ready to draw his sword if needed.

Luckily Robert and his father were further down the table, as were the Kingsguard and they wouldn't notice him until it was too late. As he slowly snuck behind the head table he readied himself. His hands were shaking slightly and sweat was starting to bead on his forehead. But he was Jaehaerys Targaryen, rightful ruler of the Seven Kingdoms and he would save them. He quickly moved forward and threw the book under his arm down onto the table, causing a loud thud sound to echo in the hall causing most to look towards the noise, he then quickly went behind Prince Joffrey and wrapped one arm around his neck while the other pressed the dagger to his throat. Now all noise ceased, all except the sound of the Kingsguard drawing their swords and moving around him.

The entire hall was now looking at him with wide eyes, his father was looking at him as if he had never seen him before and it nearly broke his heart to see his family looking at him this way.

"Jon, what are you doing?" His father asked as he slowly stood up and approached him. Joffrey squirmed a little under his arm and he held tighter, pressing the dagger so hard into his neck a bead of blood dripped down his neck.

"Saving the realm." Jon said, as he looked at the King, who was red with rage and the Queen who was glaring daggers at him, but he could see the fear in her eyes. He knew she always loved Joffrey best.

"Let him go Jon!" His sister, Sansa screamed, seated right next to him.

"I'm sorry Sansa. I can't do that." He said with a twinge of regret.

"Why not Jon? Let the prince go." Ned said as he continued to approach him from further down the table.

"I'm sorry father, but I can't."

"What is your bastard doing Ned!? Let my son go!" The King shouted, looking ready to charge at him at any moment.

Jon simply looked at him with pitying eyes before looking at the book that still sat on the table in front of Robb who was still staring at him with wide eyes.

"Robb. Brother. What book did I drop on the table?" Jon asked.

Robb looked at him with a furrowed brow before leaning over and turning the book to read the cover. "The Lineages and Histories of the Great Houses of the Seven Kingdoms." He read aloud.

"Who cares about the damn book!" Cersei shouted. Although Jon thought he saw more fear in her eyes. "Kill the bastard!" But still nobody moved, they all knew that if any attempted to attack Jon that he would kill the prince.

"Father. You have raised me to be honorable and to show courage. And that is what I am doing. Robb, open the book to the section on the Baratheons." He said.

Robb again looked confused before complying and flipping the pages until he came upon the coat of arms, a black crowned stag on a golden field.

"Now read the description of the members of house Baratheon." Jon ordered, keeping a close eye on Cersei and the Kingsguard

Robb took a small sip of his water before reading from the book, "House Baratheon was founded by Orys Baratheon, Married to Argella Durrandon. He had black hair and black eyes. Orys was the first Lord of Storms end and..."

"That's enough Robb. Next person please. Read the description only." Jon said. He could see many people in the hall looking at him with questioning looks, wondering where he was going with this.

And so Robb continued, reading the name of each person followed by their appearance. Black hair...black hair...black hair...black hair. Over and over it continued until Jon told him to stop and skip to the last four entries.

"Renly Baratheon. Black hair. Joffrey Baratheon...golden hair...Myrcella Baratheon...golden hair...Tommen Baratheon...golden hair."

Jon saw many faces now showing signs of understanding. The King still looked confused but Jon saw Cersei looking quite pale.

"This is not your son, your grace. Joffrey Baratheon, is actually Joffrey Waters. A bastard." Many shocked gasps escaped from those who did not get it before. Many now looked at the King and Queen. The Queen kept her cool mask, her eyes still glaring at Jon, but she was paler than normal. Robert on the other hand was completely pale, the rage he once had now changed to despair.

"Who?" He whispered, loud enough to carry across the silent hall. "Who's child is it!?" He shouted, rounding on Cersei.

She didn't answer. She kept her head high as she looked across the hall with pursed lips.

"Jamie Lannister of course." Jon said. All heads snapped to him as the words escaped his lips before all heads turned to the man who sat at the end of the table.

"Guards! Seize him!" Robert bellowed. Many men drew swords and approached the kingslayer, he too drew his sword and made ready to cut down any who approached him. Except a dagger went sailing through the air and tore through his hand, causing him to drop his sword as half a dozen men approached and seized him.

Everyone turned to Jon who had released Joffrey and thrown the dagger at Jaime. Joffrey, now realizing he was free, went to grab a knife to drive into Jon, but Jon grabbed the lads wrist and twisted it painfully, causing him to cry out and fall to the floor on his knees.

Cersei yelled at the Kingsguard to kill Jon but they did not move. All in the hall now knew the truth about the royal children. "Put her in chains, I'll deal with her when I return to the capital." Robert said and more men moved to grab her. She shrieked and protested but eventually she was dragged from the room, crying out for her children.

Not a sound could be heard in the hall after the sounds of Cersei's shrieks was cut off by the closing of the doors to the Great Hall.

"How? How could she do this to me!" Robert bellowed.

"Because you never loved her." Jon said in the silence that followed. "You've only ever loved one, one who never could love you in return."

"What do you mean boy!" Robert shouted. Being drunk and dealing with the betrayal of his wife had caused his anger to spike to epic proportions and he was ready to lash out at anybody.

"Your entire rebellion was a lie, Robert. Lyanna could never love you because she loved another. Rhaegar never kidnapped Lyanna. She went with him willingly. They loved each other. Hell they got married in secret!" Jon shouted.

Robert shook his head, willing the words to exit his head. "No...No! She loved me! She was mine!" He shouted.

"She did not and never could. Rhaegar dissolved his marriage with Elia after she couldn't have any more children and married Lyanna Stark in secret before taking her to the Tower of Joy. Where she died, not from rape or murder. But from childbirth." Jon said, earning shocked gasps from the men and women in the hall.

"Who is it? I'll kill the child!" The King howled.

Jon shook his head before drawing his sword, causing the Kingsguard to move forward protectively.

"Then come and kill me Robert. I am the child of Rhaegar Targaryen and Lyanna Stark. I am the union of ice and fire. I am the rightful ruler of the Seven Kingdoms!" Jon shouted at the man.

Robert paused, looking at him with wide eyes before they burned with a new rage, he charged at Jon, grabbing the sword from the hand of one of the Kingsguard and moved to hack Jon to pieces but Jon easily met the swing of the King. Robert was not the man he was at the trident, years of drinking and whoring had left behind a shadow of the man that once stood tall and proud with his warhammer.

"You never wanted to be King Robert. Go and return to Storm's End. Take Myrcella and Tommen with you. They are kind and gentle and you will grow to love them and they you." Jon said as he pushed Robert back.

"No. No! I am the King!" Robert bellowed as he swung his sword around, nearly decapitating Tommen if Jon had not grabbed the child and threw him to the floor. Robert swung so hard he spun in a full circle and then came face to face with an angry Jon, who swung hard with his fist and connected with Roberts jaw, sending him sprawling to the floor unconscious.

Jon kneeled down to the young boy and helped him to stand. "You okay?" Jon asked, giving the boy a small smile. The boy nodded and Jon stood, ruffling the boys hair before turning to the rest of the hall who were too shocked to move.

"I, Jaehaerys Targaryen, son of Rhaegar Targaryen and Lyanna Stark, claim the Iron Throne as my birthright. Do any of you contest that?" Nobody moved until Lord Eddard Stark approached and looked Jon in the eye, before a smile appeared his face and he knelt before him. The other northerners quickly followed suit, kneeling before him and after a second pause the Kingsguard as well knelt before him. Jon immediately allowed them to stand again and when he looked into his father's prideful eyes. He knew he had made the right choice. He was born to be a King. It was time to take the Seven Kingdoms and prepare them for what was to the North. Winter is coming.

Let me know what you think!
