I do not own Percy Jackson nor Game of Thrones, those writes belong to Rick Riordan and George R.R. Martin. Okay disclaimer out of the way only one I'm doing
Percy sat in the dark corner of his dirty cell, tears running down his dirty, bloody, and beaten face. Never in his wildest dreams could he have imagined his life turning upside down this fast. Yet, he still didn't regret accepting this quest. The second giant war had been hard on Percy, he had lost loved ones, suffered in Tartarus, and worst of all he had lost Annabeth. He had fallen into depression, and even attempted to take his own life before the gods stepped in and offered him a chance to start a new life.
The gods offered to send him into an alternate universe, one they had created, one free of the meddling of Greek gods, monsters, and primordial beings. The cost of Percy Jackson being reborn, was to send him on one last quest, till he could live his life peacefully, to defeat the White Walkers, and bring peace to the seven realms. Percy had agreed, not because he wanted to be a hero but because he had thought being reborn meant he would forget about his tragic past, forget about the pain about Annabeth, forget about losing all of his friends. However when Percy was born into this world, his name changing from Perseus Jackson to Perseus Stark, the gods had decided to leave his memories in tact.
Percy was annoyed by this in his younger years, being a defenseless kid again was awful, but having to go through puberty again was downright dreadful. As he got older however, he knew why the gods had left him with his memory, so he wouldn't have to re learn to use his powers, or how to fight with a sword. It all came back like muscle memory when he came of age. And he had all the knowledge of his past life, that of betrayal, pain, and battle letting him learn how to grieve and suffer but still keep moving. Something he had never accomplished in his past life.
When he was born into this world, well or transformed into a baby and inserted into this world, Poseidon had given him to Ned Stark. A blessing from the gods is what Percy was known as now, the blessed Stark, given to the warden of the north as a gift for Neds life achievements. A baby, and a sword is what Ned Stark road back into Winterfell with, and from that day Percy had become a Stark. The "second born" child of Ned and Caitlyn Stark.
Robb, was his older brother and heir to Winterfell, who was jealous of Percy when they were younger, but they grew to care for each other deeply as the grew. Jon Snow was his bastard younger brother who was hated by Percy's mother however Jon was Percy's best friend. Sansa and Arya were the two girls of the family, Sansa dreamed about being a high lady, or queen and day dreamed about living in Kings Landing. While Arya reminded Percy of himself in someways, she didn't want to be a girly girl, nor did she want to be married, or live the life of a normal women. She wanted to be a fighter, a warrior, ride in jousting tournaments, or anything opposite of what she was supposed to be. Bran and Rickon were the two youngest boys, and sadly Percy never really grew close to his youngest brother Rickon, who was really just a child. However The second youngest, Bran, Percy loved with all his heart, the little boy wanted to be a knight, or kings guard. He loved to climb, go on adventures, and would try his best to shoot a bow and arrow, which he was just as good as Percy which meant he was awful at it.
The for the first Sixteen years of Percy's new life, he had felt blessed with his new life. He had a family, a large family that all cared and loved for each other. Even if his "mother" (Percy would never consider her his real mother, as that title will forever belong to Sally Jackson) nor Sansa as she got older didn't care for Jon, Ned treated him like all his sons, and all the siblings cared deeply for each other. Percy sometimes would even go out of his way to show how much he cared for Jon, in front of his "mother" by giving Jon his dire wolf and whenever Jon was excluded from something Percy refused to attend unless Jon was present.
He was raised with the purpose of Honor, and that went very well with Percy's fatal flaw of loyalty. He had been blessed with an actual father, not that Paul wasn't a good step-father to him, but one that for his whole life gave him the fatherly advice and guidance he so desperately wanted and needed in his past life.
However, only ten days after his seventeenth name day, his life had started to go down hill. The king offered Ned the title of Hand of the King, and then Sansa was betrothed to the crowned prince Joffrey. Before he knew it, Percy's family was being torn into two. His father was bringing Percy, and his two sisters with him to Kings Landing. Sansa, as the future queen it would seem had to go, but Arya and Percy were both forced. He assumed his father wanted to find a suitable Bride for Percy, along with a husband for Arya when she came to age. Robb was to stay in Winterfell and he Warden of the North in his fathers place, Rickon and his "mother" were originally only going to be the only ones to stay with him, however after Bran fell from a tower during one of his climbing adventures and became crippled he too was set to stay in Winterfell. Jon, decided to go to The Nights Watch, something Jon had always talked about doing much to Percy's displeasure.
The long journey back to the capital had taken far to long for Percy, and often left him bored. However trouble came about when Aryas dire wolf attacked the Crown Prince, only to protect his sister of course. The queen, Cersei, was furious about the matter, and even if Ned and Robert were able to save Arya from being punished for fighting back against the Prince, they could not save Sansa's direwolf, which Percy was tasked to kill, resulting in Sansa hating him for killing her beloved animal.
When they finally reached Kings Landing, Percy began to hate his life. The city smelled like straight shit, the people were manipulative, and the city was filled with dishonest men and vile women. His rarely saw his father, as he was busy dealing with the politics of running a country, so Percy spent his spare time sparring, training, and carefully watching from the background to see those he could trust and not trust. It seemed his father, sadly had not thought about the trustworthiness of the men of the small council as they manipulated him in his downfall.
Nine months of being in Kings Landing, would have never prepared himself for the events that had just taken place in the last week. The King, Robert Baratheon had died in a wild hunting accident, and his son Joffrey was set to take the throne and become King. However it seemed Percy's father had uncovered a conspiracy, revealing that Joffrey wasn't Roberts son at all, instead Jamie Lannister's bastard child, meaning he was a product of incest as the Queen was Jamie's twin sister. His father had proclaimed that Roberts brother, Stannis, was the rightful heir. No matter what Percy's father had prepared, it didn't work out. As he was captured and accused of Treason. The consequences of the truth Percy's father had reveled, fell upon his children in an awful way.
Percy had been sparring with Arya, something he had started doing to help pass the time and to bond with his little sister, when the soldiers came barging into their tower. Winterfells soldiers, loyal to his father, were slain down. Shocked at the sight of men being slaughtered and clueless at the time of his fathers actions, did his best to save Arya. With out hesitating he had drawn his sword and stood in front of his sister protectively as he sliced down the men that had so suddenly rushed them. He screamed for his little sister to run, and thankfully she did leaving Percy some hope that she was alive and well.
He had no idea how many men he had killed before he was surrounded and beaten. He was thrown into a cell at first, before being released to being trapped in the comforts of his room. The only time he was let out was to try and convince his father to sign a paper and be sent to the Nights Watch, saving his children's lives and his own. All he had to do was bend the knee and proclaim Joffrey as the one true king of the seven realms.
He had thankfully convinced his father to agree, even though it meant him lying as he told Percy the whole truth. At the trial, Ned had done what was asked of him, before Joffrey seemed to change his mind on his agreement to send Ned to the Nights Watch and instead ordered to have him beheaded. Despite Percy's best efforts, he could not save his father from his fate, resulting in a devastating storm to hit Kings Landing. In Percy's anger, a hurricane of sorts had suddenly sprung from the sea, and the ground began to shake furiously which Percy supposed was an Earthquake. It took ten men to beat him unconscious, and then the storms stopped, revealing to all of Kings Landing that Percy was truly the blessed Stark of Winterfell.
That left Percy, sitting back in a cell beaten and bruised marked as a danger to society. He had no idea what his fate held for him now. If Joffrey and the rest of the Lannister's that now has control
over the throne and the seven realms, they would kill Percy. If they were dumb however, Percy would be kept alive and would be able to take revenge on those who betrayed his family, and killed his father.
