Okay, so this is my Targaryen OC. This time it's a younger twin brother of Viserys named Aegon. Edit: I changed the story from the original story so bear with me. In this story, Jaime, after killing the Mad King, feels guilt over how he didn't protect Elia and her children. Varys then sees this and whisks him away to Dragonstone to protect the royal family. However they get separated and Jaime now has to care for Prince Aegon and Princess Daenerys. And I'll let the story explain for itself. For now, enjoy.

Jaime

My Prince,

I have a feeling that the Usurper's days are numbered. The Lannisters will try to take the country and destroy those who oppose them. I beg you my prince, you are ready for this. Take your army and cross the sea. There are many who will bend the knee to you. You are not your father or your brothers.

Please my prince, for the good of the realm.

The Spider

Jaime looked at Aegon the entire time he read the letter aloud to him. The new king of Westeros seemed to be deep in thought. He has been training for this for a long time now. Since he was five all he's ever done was train, in both body and mind. And he's proven himself to be a very capable leader. He did this by completely taking over the Golden Company at the age of sixteen. He challenged Myles Toyne to single combat and the first to yield would be either given the Company, or Aegon would have to look elsewhere. It turned out to be the former, and Toyne stepped down and Aegon took control of the Company. Jaime knew he would win because of the training he gave Aegon. It took a long time before Aegon got to be as good as he was, but he excelled beyond Jaime's expectations.

Ever since then he had been growing the Company's soldiers. When he started, they were about twenty thousand strong with two thousand horse. Now they were thirty thousand strong with ten thousand horse. Aegon did this by not necessarily invading, but conscripting warriors who searched for glory. And many came to him, men from Myr, Braavos, Norvos, even places like the Summer Islands and Qohor had men line up to join the young Targaryen prince in his conquests. During that time, he also proved himself in battle as well. When he was in Lhazar, Aegon had to contend with a Dothraki horde, ten thousand strong. However, he knew he couldn't meet them in open battle. So while they slept outside one of the villages drinking and fucking, Aegon had his archers, led by Black Balaq fire flaming arrows on their tents and take their horses, while he led his own cavalry to fight them. The victory was won though not without its casualties, Myles was killed by the khal Moro, who was later killed by Jaime himself. But the strategy worked and the Lhazareen people rewarded Aegon with a feast filled with lambs. Jaime jested it as "A Feast for Dragons" as Aegon once jested that a dragon eats lamb, when he actually saved them. From then on, whenever someone from another city with an army tried to oppose Aegon, he would beat them back. Aegon was looking at the scroll for a long time before turning back to Jaime.

"So. It appears that the time has come to lay my claim on the throne." He stated.

"That's what Varys tells us." Jaime responded.

"I have thirty thousand men and ten thousand horses. We need more."

"You can't." Jaime insisted.

"Are you presuming to tell me what to do?" He asked.

"No I'm telling you that we have no time." Jaime said firmly. The boy may be of age and older, two and twenty, but he still had much to learn, especially about his father. "My father will defend my nephew, his grandson to the bitter end. He doesn't care about anyone else, he cares about his legacy. The legacy of House Lannister. You know how your niece and nephew met their ends. My father will destroy hundreds of families if it benefited his house." He explained. Aegon sighed heavily.

"I know. Well, it looks like I have no choice then." Aegon said resigned.

"I know it seems like a hard choice. But this is the right thing. If we land now, we could deal with your enemies with ease."

"And who are my enemies?" Aegon asked. "If I set sail. Where will I land?" He pointed to the map. "Where would I land to get allies?" Jaime thought about it for a moment. While there were some places that could be useful, there was only one thing he could think of.

"The North." Jaime said. Aegon looked to him confused.

"The North?" He asked. "Why not Dorne? They would support me." He suggested.

"That would be a smart move. But the fighting is in the Riverlands right now. The Starks would have to gather their forces and defend it, due to Ned Stark's marriage to Catelyn Tully. My father is invading it right now. If we sail to the North and join their forces and retake the Riverlands, that will prove to the country that you care about your home. Remember your lessons? How the first Aegon took Westeros?"

"I know that. He took his dragon and burned Harrenhal. I don't have a dragon." Aegon said.

"No, but Aegon liberated the Riverlands from the grip of a tyrant. My father is invading, you defend it, and, well, you finish the rest." Jaime said. "That's all I can offer you lad." Aegon seemed to be in thought once again. Jaime studied him for a bit. Aegon always knew that a ruler doesn't win the people by proclaiming himself king or prince throughout the world. It's done by their actions. And those actions and Aegon the Conqueror's mercy won him the Seven Kingdoms. Aegon looked to Jaime at that point.

"So the North? But won't they hate me when I arrive? My father was responsible for their lord and his heir's deaths."

"Your father, not you. And I can vouch for you. I saw it happen. And I knew it was wrong then." Jaime responded. "You just need to prove yourself to them as well. The Northerners are proud people, they respect strength and honor. Your houses may have had some better times but recently it all fell apart. Some may be wanting to kill you, but not if you prove your strength by helping them deal with my father."

"You may be right." Aegon said. Then he looked determined. "Alright then. We have our fleet here in Pentos, four hundred of them. We use it to transport out men west. Let's hope the seas won't give us any trouble. Or pirates."

"Pirates won't give you any trouble." Jaime told him. "Just ask Euron Greyjoy's eye." They both chuckled at that. A few years ago, they were caught off guard by Euron Greyjoy's fleet, they fought them off bravely though at a high cost losing several of their ships in the process. They had about nine hundred ships when they fought Euron and he had only a few hundred. But he managed to sink them. However not all was lost. Both Jaime and Aegon and some of their best men managed to board Euron's ship. Jaime fought him in single combat but Euron somehow managed to subdue him, but it was all for naught. Aegon came and dueled with him and Jaime never saw a duel more brilliant. Aegon managed to cut Euron's eye blinding him for a moment before getting to Jaime and retreating back to their ship where Euron retreated as well. There were a few prizes though for Aegon when they fought Euron. The men had managed to capture armor that resembled Valyrian steel and a strange horn, but Aegon heard of it. It was called the Dragonbinder. He immediately set fire to it and the thing went up in smoke. Aegon later told him that no one should try and control dragons, only his family would be worthy enough to ride them. If anyone else had it then the world would suffer, especially in the hands of someone like Euron. Jaime didn't argue about it.

"Well in any case, we should prepare." Aegon said strapping his sword to his waist. The sword in question was one of two swords that was reforged from another sword. That sword was Brightroar his family's ancestral sword that Tommen Lannister lost in his voyage to Valyria. The sword was found in Valyria itself. Though Aegon almost didn't make it out with his life. He lost one hundred men trying to find it, and another fifty trying to get out of there. He eventually brought the sword to Qohor where they demanded a blood sacrifice to reforge the sword. One of their men volunteered a Lyseni man and the sword was remade into two. The one Aegon carries with him, it's color was all black and the sword that Jaime now carries the color all red. Both swords were named Balerion's Flame and Lion's Roar respectively. Aegon gave Jaime the other half of the sword because of his service to his family and because the sword was a Lannister sword. He went outside to find all the troops in assembly in good order. Black Balaq was ordering the archers while Strickland was ordering his troops in good order. Jaime was confident in the men despite Strickland not being much of a soldier, but he held the Company together. Jaime could feel it in his bones that this could work. They could get the kingdoms back. But Aegon would have to win over the kingdoms, in the way his ancestors did, with steel and fire. He could see Aegon getting on board his ship, The Black Dread. Jaime followed him to his cabin where his prizes were hanging about. The Valyrian armor, the sword and to even Jaime's surprise, four dragon eggs. Aegon had found them as well as Brightroar when he went to Valyria, each of the eggs had different colors. One was a dark blue color, one a ruby red, another a violet color, but the last one was an all-black colored egg. It reminded Jaime of the stories of Balerion the Black Dread. Though thankfully the eggs would never hatch.

"So the journey to White Harbor could be a few weeks at best. Once we land, we will raise a white flag and speak to Lord Manderly and let the Lord of Winterfell know that we are there to help. Hopefully they'll be able to listen." Aegon commented almost to himself.

"They will. Have faith." Jaime said. "You can convince them you did the same with the troops here, you'll do well."

"Well, it's your family we're going up against. Are you sure you're alright with that?" Aegon asked him. Jaime knew the answer to that.

"I am. My father never cared for me. All I was to him was a legacy. Same with my sister and brother. Of course, well, my sister… let's just say I wouldn't mind seeing her die." He said. It was true, they had parted on bad terms. She thought he was an idiot for mourning the Targaryen children and Elia, calling her a useless whore. That drove Jaime over the edge. That's when he took Varys' offer to protect Aegon and his family. He also knew about Cersei's children. Joffrey was his seed, nothing more. But Tommen and Myrcella must have been fathered by someone else.

"But, it's your family." Aegon insisted.

"Tyrion is my family. My uncles and cousins are family too. My father and sister can go to all the hells in the world. My nephew Joffrey too." He said, making a point to call Joffrey his nephew instead of his son. Only he and Cersei knew the boys true parentage.

"Alright." Aegon said sympathetically. Just then the door opened to Aegon's sister, Princess Daenerys. Even at seventeen she was a breathtaking beauty. Jaime once told her she reminded him of her mother. She was brought along with Aegon after Queen Rhaella gave birth to her and died. The three remaining Targaryens went on separate ships, but Viserys' ship was caught in the storm and sunk. That just left Aegon and Daenerys for Jaime to care over. Not that he minded, both of them were like the children he never had. They were more his children than Cersei's. "Dany." Aegon greeted. "What's wrong?" He asked gently.

"Everyone is moving about. Are we going somewhere? No one is telling me anything." She replied.

"We are going somewhere Dany. Home." Aegon said.

"Home?" Dany asked hopeful. "It's time?"

"It is sweetling." Jaime replied. "You and your brother are heading home. But first we're going to the North, I'll explain more when we set off." Dany ran up to Aegon and gave him a fierce hug.

"We're finally going home." She whispered in his chest. "Home." Dany said again before leaving.

"Well then, we should get some rest. We have a long journey ahead of us." He said before bowing his head. "Ser Jaime." He said. Jaime bowed his head.

"Your Grace." He replied before leaving the cabin. As he left, he felt a swell of pride in his chest. They would win this. He knew it. And House Targaryen would rise above the ashes. The next day, the army was setting sail to Westeros, to take everything back. For Aegon, Jaime would die if it meant Aegon would sit the throne one day. And Jaime would be content with that.

Okay, so I know this will probably seem similar to DannyBlack70's "The Golden Dragon" considering Aegon has the Golden Company and has fought Euron, but here's the thing I've found out in Fanfiction. There are many people who copy other's work and just change the name of their characters claiming it's theirs. That is not my intent with this story. There are story changes, one of the big ones is that Jaime left for Essos and raised Aegon. Viserys is dead and Dany is with Aegon, who is a much better older brother to her, though not in the traditional Targaryen way. They won't be a couple. Aegon had to win his place as leader of the Golden Company. They grew to about thirty thousand and have faced the Dothraki. So I hope that sort of clears it up, but this is the story, and hopefully I did it alright. I'm already working on the next chapter, so maybe that'll be up in a few days, maybe a week. Who knows? Leave a comment and reviews and I shall see you next time.
