Jason POV

294: Casterly Rock

He walked as fast as he could through the hallways of Casterly Rock, a pox had swept through the castle, his uncle Tygett, had already died a few weeks past. Now it looked like the stranger was finally coming for Lord Tywin of the House Lannister, the mighty Tywin Lannister, the one who drowned the Reyne's in their mine and brought Tarbeck Hall down on the Tarbeck's heads, killed by a pox.

He and his father had close when he was younger, but that all changed when his brother had married a common girl, Tysha a few months after the Lannisport tourney that his father had thrown. When the septon that married them had confessed to his father he became filled with rage. Ellyn Reyne's laughter had come back and haunted him, that laughter that he wanted to bury as deep as he could. The mere thought of a Lannister marrying a commoner had infuriated him, he searched every corner and ally of Lannisport. He found the girl, she was about a year older than Jason and Tyrion were, she had black hair and blue eyes, she was quite pretty for a peasant. Jason and Tyrion had met her while they were out riding just outside Casterly Rock, she was being chased by three men who were drunk out of their minds, likely wanting to rape this girl. The sight of Lannister colors that Jason had on his horse and the Valyrian steel that Red Rain was made of had likely given away his identity and they ran away. Tyrion took the girl to an inn and fed her while Jason chased after them to teach them a bit of a lesson in manners.

Jason knew Tyrion had fallen for this girl, quite frankly he was happy for his brother, he had married Margaery two years ago and their marriage had been a very happy one, with their one year old twins, Loren and Leo he wanted his brother to be as happy as he was. He didn't know however that Tyrion had married her, when his father had told him he was quite surprised, he didn't think that Tyrion could be stupid enough marry someone of a lesser station but he couldn't exactly blame him, most of Casterly Rock had teased him for his condition, Jason did whatever he could to prevent this going as far as to threaten Cerion Lannister, the Lord of Lannisport telling him that he'd have him fed to his grandfather's lions if Tyrion ever came to him crying about something he said again. But even Jason couldn't be with Tyrion at all times. So, Tyrion marrying this girl was somewhat understandable considering that the boy hadn't known a woman's affections and this girl had given him just that.

His father then had the girl practically dragged to the Rock and threw her in a cell. He tried to command Jason to tell Tyrion that Tysha was a whore that he had hired because he wanted Tyrion to become a man. Jason however strong willed as always had refused claiming that he wouldn't lie to his brother, Tywin commanded him to tell Tyrion that the girl was a whore and afterwards she would be given to the household guard in the barracks for a silver each and Tyrion would be last and he would be worth a gold dragon. Jason became red with rage when his father suggested that saying that dwarf or no this boy is a Lannister and his son, and a son of Casterly Rock. He marched out of his father's solar and gave the girl a bag of silver and put her on a ship to Oldtown, so she could start a new life. The girl hadn't even known that Tyrion was a Lannister and she told him that she truly loved him, making the whole situation even worse. After that event Jason and his father were never quite as close and they had once been, true his father still loved him and he loved his father but he hated acting as a mediator between him and Tyrion.

Now his father was dying, he barged into the room. In the room was his uncle Kevan, his aunt Genna, his brother Tyrion, and maester Creylen. He saw his father drenched in sweat, he had lost a lot of weight becoming a mere shadow of the father that told him stories of the nine penny kings and the Reyne Tarbeck rebellion.

"Jason, my son. Come closer." Tywin said his voice barely a whisper. "It's my time my boy, I'm going to see your mother. By this time tomorrow you'll be Lord Lannister, my legacy and everything that I've built is all yours. Do me proud son, you're a Lannister, a golden lion people are going to try to gain power and worm their way into Casterly Rock, be strong, allow them no power and should they rebel show them the price of defiance. You're a good lad, you've got more of your mother in you than any of your siblings, you're a better father than I could've ever been. Teach Loren and Leo to be Lannister's and to continue the legacy, and carry on the family name."

"I promise father, I promise I'll uphold the pride and power of House Lannister, I'll build us to greater heights than we've ever been, the world will hear me roar." Jason said holding back tears.

And with that Tywin Lannister died with a smile on his face at the age of fifty. His aunt Genna and uncle Kevan clearly upset had left the room when the life had left their brother. Tyrion however wore a blank expression, the man that tormented him all his life saw to it that he would always ensure that he knew that he killed their mother was dead, but at the same time it was his father, if he truly hated him he could've thrown him into the sea after his birth, but no, he raised him as a son of Casterly Rock gave him the same gold and education he gave Jason save the fighting lessons so he was clearly conflicted.

Jason left the room as quickly as he could when the silent sisters came. Walking, numb to the people offering him condolences and the bells that had begun ringing. He made his way to the chambers he shared with his wife. He found Margaery sitting on their bed reading a book in a soft silk nightgown.

"She had been waiting for me." He thought. As soon as that door closed his wife stood up walked to him and wrapped him in a tight embrace, Jason almost immediately burst into tears.

"Come my love, all men must die. It's a part of life, all we can do is mourn and honor their memory." His wife told him.

She released him and took his hand in hers and lead them to their bed. All night she comforted him as only a woman could.

A few days later his father was buried, his sister Cersei, his good-brother Robert, their children and her brother Jaime had just barely missed their father's last moments arriving a day after their father's death. All seemed sad except for Robert, the man was laughing, japing and drinking at his father's funeral. Jason was determined to make that fat drunk pay for every last jape he had made.

He sat in his new solar everyone still shaken from his father's death. In front of him sat his uncles Kevan, Gerion and Stafford, his aunt Genna, his brother Jaime and Tyrion, his sister Cersei and his cousins Lancel, Tion and Cerenna.

"So, I've called you into this solar for a reason. Father always had viewed Tarbeck hall and Castamere as monuments of his ruthlessness, and because of his ruthlessness House Lannister has quite a few enemies, the biggest of them being House Martell. So, I intend to make peace and create a few alliances, also I'll correct a few mistakes that have been made." Jason began. Everyone looked confused as to why they would be needed.

"I'll start with Aunt Genna, this marriage between you and that Frey man was probably the worst thing that grandfather did in his years. So since I technically can't undo this marriage, Emmon and the rest of the Frey brood except Tion will be sent back to the twins. Tion is the only one of your children that shows his Lannister blood, so he will become the Lord of Tarbeck hall when he comes of age, though I suggest that changing your sigil would be necessary a bridge wouldn't make sense, you can even start your own house if you want." He turned to Tion "I've seen how you and Joy are together so, I got Robert to legitimize her and you two will wed when she turns sixteen." Tion nearly tore his lips grinning so hard, causing everyone in the room to laugh.

"Next is uncle Kevan, now that Tarbeck hall has a lord it's only logical that Castamere has one too. So, I've already given the order for the mines to be reopened and the gold and silver found in those mines will be used to rebuild both Tarbeck hall and Castamere. Lancel as your heir will marry Gwyneth Yronwood when she comes of age. Cerenna, I'm trying to arrange for you to marry Prince Quentyn Martell, don't worry I've already invited Prince Oberyn and he'll come collect Gregor Clegane and Amory Lorch, plus if the Martells agree to the marriage he'll squire for Jaime or myself." Jason finished

"Uncle Gerion, I'm going to need you to take fifty men and arrest Lorch, Jaime you're probably the best fighter in the realm, after me of course" Jason japed. "Take one hundred men and get Clegane, bring them both back here, have them thrown in cells and chain them to the walls of the cell so neither escape."

"Excellent plan big brother, what of me." Tyrion asked.

"Well, since you've made it quite clear that you won't marry and that you enjoy whoring and traveling, I want to send you and uncle Gerion to the Prince of Pentos, the Sealord of Braavos and the Rogares of Lys, I need you to discuss trade deals with them to expand our own wealth. Uncle Stafford I need you to lead a mission to find some new mines, this current mine that we use will run dry in a few years and I can't let that happen. After much digging I found that Cerion Lannister has been stealing from the Rock and not paying his taxes so I may have sent him and his sons to the wall, meaning there's no longer a Lord of Lannisport so the Lannisport lands will be combined with that of Casterly Rock." Jason said with a smile. "I'm also making some changes to the household as well. The Castellan will be Uncle Stafford, Ser Benedict died of the pox not long after father so I've arranged for Strongboar to become master at arms and Edric Payne will become the High Steward of Casterly Rock. Oh, and I talked to Robert, Joff will serve as a page here and I'll teach him to rule just as father did with me, Jaime will be the kingsguard protecting him."

Cersei seemed quite conflicted, and everyone else looked quite satisfied.

"My lord I cannot thank you enough for the honor you've done me, I promise to serve you the best I can." Kevan said kneeling.

"Rise uncle, you've served House Lannister for nearly thirty years, it's about time you were rewarded for all your years of service." Jason replied.

"Well, seems House Lannister is in good hands, I always knew you'd make an excellent lord Jason." His aunt Genna said with a smile.

"Well, let's get to supper, I'm starving." His uncle Gerion said with a laugh.

Margaery POV

Loren and Leo were both a sleep in their cradles, both boys were very different. Loren was quiet and only really cried when he was hungry, Leo however was a wild child, he was full of life and extremely fussy. Her heart swelled with love at the sight of her two boys, Loren was a pure Lannister he had golden hair with his father's green eyes. He had the same jaw, cheekbones and pouty lips her husband had, very much his father's son. Leo however had more of her in him he too had golden hair but he had her big hazel eyes and her button nose, she knew he'd grow up to look just like Loras or Garlan when he grew.

The door to the nursery opened and she felt strong arms wrap around her. She turned back to see those beautiful green eyes that she loved so much. She had quite a happy marriage with her husband, she thought that he was putting on an act so that she'd consent to the marriage and once the marriage was consummated he'd turn into a whoring brute who only used her as a broodmare. But she was wrong Jason was kind, smart, funny and strong, he was almost godly beautiful to where women would giggle whenever he would smile at them. She always felt a bit of jealousy overcome her whenever she saw the way women were with him but he never failed to reassure her that he loved her and only her. Her grandmother told her to use him and to wrap him around her finger so that she could use him to gain power for her house, but she'd fallen in love with him and she couldn't bring herself to try to manipulate him for her families benefit. She however was his closest advisor, he told her everything and actually listened to her advice, which made her love him more.

"I haven't seen you nearly as much as I used to since the king arrived." Margaery said with a frown.

"Sorry Marge I try but being a lord is extremely time consuming work. With the King wanting to go hunting every other day and Cersei wanting me to teach Joffrey how to rule it's quite difficult for me to have time for myself." After a moment of silence Jason continued. "But I'm their father and your husband too, I'll make more time for them my love I promise." Claiming her lips as his own. They walked into their new chambers and made love four times that night. Hopefully she'd give him another child, a daughter maybe? Yes, a little girl would be nice.

The next day she sat in the great hall next to her husband while he was sitting on the lion's throne while holding court, the Queen sat next to her while her husband's uncle Kevan sat next to him. The court was going as usual Jason dispensed justice and listened to people's complaints. When the servant called for the next person to come up three men wearing Frey sigils walked up to the front of the great hall.

"And who might you three be?" Jason asked.

"I am Black Walder Frey, this is my uncle Walton Frey and my cousin Steffon Frey" He began.

"We have come here on the authority of my father to demand that you return Lady Genna Frey to my uncle Emmon."

"Over my corpse, she is worth more that the entirety of your house combined." Jason snarled. "Tell your father, grandfather, great grandfather or whatever the fuck Walder Frey is to you that he can go fuck himself, you're in no position to make demands of me, I am the Lord Paramount of the richest house in all of the seven kingdoms, I descend from the blood of kings, so I'd advise the three of you to leave."

"We won't you will reinstate this marriage or else we'll have to take action." Walton said almost shouting.

"You've insulted the honor of our house you son of a whore don't you dare speak about our Lord Walder that way." Steffon said.

The entirety of the hall went silent, the tension was so thick you could cut through it with a knife. Cersei was almost red with fury, Jason however had a blank emotionless face, but his eyes were as cold as the lands of always winter. Margaery herself was quite worried, as well as she knew Jason did not know how he would react to this, his mother was always a touchy subject for him.

"Guards, seize them take them to the execution yard." Jason said his voice was as sharp as steel. He turned to his cousins Lancel and Devan. "Lancel, run up to my chambers, fetch me Red Rain. Devan go to the armory and find me something that I can use as a chopping block."

Both boys ran separate ways while the guards had grabbed the men and began dragging them to the yard. Her good-uncle Kevan looked at his nephew with a surprised look on his face while Cersei seemed delighted that the men that insulted her dead mother were going to die.

Some minutes later Lancel came back with her husband's sword, he took it and the entire began walking to the execution yard. All three men were then put down by the guards upon sight of their liege, Jason drew his sword and stood next to Walton Frey.

"If you have any last words Ser, now it the time." Jason said.

"Please my lord, I beg of you. Forgive me I was only following my father's orders." Walton pleaded.

With one swing of Red Rain Ser Walton Frey was dead. Steffon and Black Walder just Walton both pleaded with Jason to forgive them, but Jason would have none of it once he beheaded both of them he ordered their heads to be sent to the twins to serve as a warning.

As the did every night, the Lord and Lady of the west lay together Margaery's head on his bare chest as he explained what he intended to do with the Martells.

"If your plan was to work, you'd unite the South and we'd be the most powerful house." Margaery said.

"And you and I would be king and queen all but in name, we could make our way into the small council after that, the king owes me something like two million dragons, your father another million and the other houses of the west and the reach a combined million. The mighty Robert Baratheon would be our bitch." Jason said making Margaery laugh as she lightly slapped her husband's chest for his vulgarity.

Authors note: New chapters start tomorrow, I have a few ideas for the whole Martell thing, but it'd be quite similar to another story where the Lannisters have Robert by the balls. Oh and I need some original house names for the new house that rules Tarbeck hall, feel free to leave some ideas.
