Casterly Rock was just as grand as she had been told it was. The castle sat proudly on top of a vast amount of rocks, looking out the glimmering sea. The views were spectacular and the castle decorated even more so. She wondered if she had ever seen such a sight before. She kept silent as she stood on the balcony, awaiting her parents to return to her. She kept her hands on the stone and her back straight. She did her best not to slump, recalling the manners which her mother and septa had taught her to have.

She continued to stare out to the sea, watching as ships sailed, her green eyes alight with wonder. At the age of ten and seven she often found pleasure in simple things she had not seen before. She had never been to the coast, but the sea air was so refreshing against her pale skin. She could not help the smile on her face.

It was only when she heard the door to the solar open did she turn around and look behind her. A simple net curtain was the only thing which separated the balcony from the solar. She placed her hands into her skirts as her parents wandered back over to her. She noted that they were not alone. A tall man walked behind them, conversing with her father of matters. Her mother beamed to her before opening her arms, urging her daughter to move forwards.

"Elena," she called and the girl slowly moved, her eyes still glancing between the three adults.

Her mother bent slightly and rested her hand on her daughter's back, just by the end of her soft brown curls. The green gown she wore was a deep colour with intricate flower detailing on the bodice. Elena bent into a curtsey in front of the visitor her father was speaking with.

"And this is your daughter?" he checked.

Elena met his cold stare. He had white hair on top of his head and was tall with a stiff posture. A lion pin occupied his chest and Elena wondered if this was the mighty Tywin Lannister she had heard of.

"Lady Elena," her father spoke. "This is Lord Tywin."

"Pleasure to meet you," Elena spoke and Tywin gave a stiff nod.

"Has she bled?"

Elena seemed confused at the intimate question. She looked up to her mother who answered for her.

"She was a late bloomer, but she has now bled," she promised him. "I have no doubt that she is fertile."

Elena could not help but allow her brows to furrow together and her forehead to crease. Why did it matter if she was a late bloomer or not? Why did any of it matter? She kept silent for a few moments and watched as her father smiled proudly.

"Good," Tywin spoke. "Perhaps we should take this conversation to my private rooms, Lord Marcel?"

Markus Marcel nodded in haste, leaving his wife and his daughter in the guest chambers before walking away. Elena then looked up to her mother, hoping that she could clarify what had just happened. Her mother continued to beam until the door was closed and then her eyes closed and her smile disappeared. She had to be strong for her husband. His word was law and he was deciding what was going to happen to their only daughter. She did not agree to it, but she had no say. She was a female and his wife. She had questioned him but it had not ended well.

"What is happening, mother?" Elena wondered. "I have a theory, but I do not want to be correct."

Mary Marcel nodded and looked to her daughter, taking her hand and leading her to the stone bench on the balcony. They sat down on it and Mary wrapped her arm around her daughter's shoulders tightly.

"There is a reason as to why we came to Casterly Rock," Mary admitted. "But I think that you know that reasons. Lord Tywin has a son...and...he wishes for him to marry. Your father thought that it would be a good match. House Lannister is powerful, much more so than House Marcel."

"Which son?" Elena asked.

She had always known that her time to marry would be upon her. She did not like it, but there was nothing that she could do about it. She could run away. She could run and forget her problems. She could forget the fact that she was nothing but a pawn for her father to pass of when he felt the time was right. Her mother had told her that too. Her mother had not wanted to marry her father, but their marriage was not entirely loveless...well...when her father was sober.

"Jaime," Mary spoke and Elena shook her head. "His sister is to marry soon and you are to marry Jaime should Lord Tywin allow it. We cannot waste Lord Tywin's time. He is Hand of the King and should be in King's Landing. It is a miracle he is here."

"But I would have to move here?" she checked.

"Yes," Mary said. "I tried to stop it, my love. I would keep you with me if I could. Believe me of that."

"I know," Elena said, her head resting on her mother's shoulder as she kept silent and still, wondering what was going to happen.

...

Tywin had dismissed Markus Marcel as soon as his son came storming into his office. At the age of eighteen, Jaime Lannister was a young man. His blonde hair gleamed in the sun and his youthful looks were enough to make him the envy of many men and the lust of many women. Tywin shifted through his papers and looked to his son who pushed past Markus. His eyes were narrow and he wore a simple shirt tucked into breeches with a coat over his shoulders.

"I will not marry her."

Tywin continued to glower, paying more attention to the papers in front of him than to his son. Jaime soon saw to that. He acted brashly, pulling out the chair to the desk and throwing it to the floor. It was only then when Tywin moved his stare back to Jaime.

"Do I have your attention now?"

Tywin ground his teeth together. He should have been prepared for his son's rage. He should have known that Jaime would act in such a manner. Tywin had caught wind of what had happened during Jaime's stay at King's Landing before he travelled for the Rock. Tywin knew what he intended to do and he would not allow it.

"You will marry Elena Marcel," Tywin dangerously spoke. "I shall not have you serve on the Kingsguard and throw everything away. I shall not have rumours spread about you and Cersei. You shall marry the girl, father her children and learn your role as Lord of Casterly Rock."

Jaime's eyes widened and he continuously shook his head during his father's speech. He would not do it. He would not have the girl.

"I do not want her."

"It is not a matter of what you want," Tywin assured his son. "It is what you shall do, and you shall marry her. Did you honestly think that I would let you leave for the Kingsguard. You are my son."

"You have another son," Jaime snarled.

"He is not fit to be my heir, nor will he ever be," Tywin spoke, his voice still level that Jaime wondered how he could be controlled and cruel at the same time. "Cersei shall remain in King's Landing and you shall stay here. I do not wish to listen to foul rumours spread of you anymore. We are not debating this, Jaime."

"I will leave-"

"-You will grow up," Tywin snapped and then stood up, his fists slamming on his desk as he did so. He lifted his gaze to meet Jaime's, noting how his son cowered slightly under his intense stare. How could he not? "You will be a man and you will do your duty. Elena Marcel is a comely girl. I am sure she will give you heirs. You will not disgrace the Lannister name anymore."

Jaime felt his teeth grind together. How could he accept this fate? How could he stand there and allow his father to dictate his life to him? He did not know, but he did know that he had nothing more to say on the matter.

"Now, go and prepare for the feast tonight. I make the announcement then and you shall wed and bed her by the end of next week."

"Shall I?" Jaime snapped back.

"Yes," Tywin dangerously replied. "Now get out of my sight and do as I say."

Tywin took his seat, only looking up as he heard his son leave the room. He knew that Jaime would contest his decision for many more days to come, but Tywin did not care. Jaime would do his duty; Tywin would see to that. He would do his honour and he would complain no more.
