In the TV show Robb is about 20 so I made Myrcella about 16. She was heading to Casterly Rock for safe keeping.

"Uncle Jaime, why is it taking so long to get to Casterly Rock?" Myrcella asked, a whining note in her voice as she brushed through her hair one night at camp. It was so tangled from the ride that she struggled with getting the brush through it where she sat on her cot with her legs folded beneath her like a child as she sat there in her shift. "I know we're not going directly there. I do know which way is west and east."

"Cella, there are plenty of enemies between us and Casterly Rock." Jaime told her. "And I have more things to do than get you safely there."

"Mother said you were going to see me there." Myrcella said. "I do not like traveling on horseback. By ship is much nicer for me."

"You should have told your mother that." Jaime told her. "Then you would be in a ship right now instead of a tent with soldiers."

"Yes, and how am I supposed to feel safe here?" Myrcella demanded. "In the open, I thought there was war going on with the North...the stories I've heard..."

"Don't you worry, Myrcella," Jaime said. "You have the best fighter in all of the seven kingdoms protecting you."

Myrcella looked up at him, her green eyes large. She looked just like her mother did at her age. "Robb Stark hasn't lost a battle."

"You met the boy a few years ago, do you really think he could beat me?" Jaime asked.

"Maybe not. But his wolf could. They were large as puppies, Uncle. I don't like thinking about you out here. Or Tyrion, wherever he is now."

"He is with your grandfather. There is nothing to worry about." He told her. "Now go to sleep. We have another long day ahead of us."

Myrcella stared at her uncle for a moment, before she plaited her hair. "I'm still worried. If mother felt the need to send me away, it can't be safe there, can it?"

"She's just making sure her only daughter is safe." Jaime said. "And I am the only one she trusts to get you there."

Myrcella pouted. "I still say a ship would have been easier. There are no armies that way."

"But there are Iron Islanders. Ships from the Free cities. Ships from Dorne." Jaime listed.

"I get it." Myrcella said. "I understand. People want to kill me. They don't know me, but they want to kill me."

"They don't want to kill you." Jaime said. "If they have any mind for war they'll want to ransom you, but even then that doesn't mean you'll be safe."

"You mean they would rape me?" Myrcella asked. "I know. Mother told me."

"So you know how serious this is." Jaime told her. "Now go to sleep. I have a meeting to go to." He said before sweeping out of the tent.

"Goodnight to you too." Myrcella said softly, before getting under the blankets on her cot. She didn't want to go to sleep, but she did know better than to think the next day would be easier than today.

It was cold out-or it was cold to her. She was used to the heat of King's Landing. The stone around her reverberating the heat back at her so it was hitting her at all sides. She curled under the blankets, her legs sore from the ride. She fell asleep quickly, far quicker than she imagined, and when she awoke she heard yelling and running around outside.

Myrcella's blood ran cold. She knew better than to think those yells were of joy or celebration. She reached for the dress she had worn yesterday, where a dagger was. A dagger Jaime had given her when they began moving west. As she shifted her clothes around, trying to find the metal, and not cloth she saw someone walk in. A man she did not know just as her fingers grasped around the hilt. She took it from its sheath and held it before her. He wasn't one of the Lannister men. He couldn't be. He was Northern, with his dark armor and his face covered with a helmet.

"Stay away from me." Myrcella said, her voice strong, but as she stepped back she stumbled slightly.

"I didn't know that Lannister kept a whore with him." The man said, pointing his sword at her. "Put the dagger down."

"I am not a whore." Myrcella said, but she didn't know if she should say who she is-she didn't know how her fate would change with her name.

"Doesn't matter." He said, stepping towards her as other men entered the tent, dressed similarly to the first man in her tent.

"We have the Kingslayer." One of them said. "Now get the girl and let's get out of here."

One of them jumped towards her, and she jumped back, only knowing that the point of the dagger was to go into the one attacking her. She didn't see any open skin on this one, but he did have a sword-unlike her.

"K-keep your distance." She told him. Her hand that held the dagger was shaking as she stood there in her shift. Hair from her braid falling out around her face.

The soldier grabbed her wrist easily enough, and twisted it behind her back, before hitting her in the head with the hilt of her sword, hard. Everything went black for Myrcella.

Myrcella awoke being carried over a man's shoulder. Her wrists were bound together, hanging below her head, which was throbbing in pain. She needed to get away. She needed to get home.

She didn't know exactly what to do other than her legs were being held rather tightly. She did have the strength to straighten her body. She just hoped that would be enough to make him stumble or something.

So she straightened herself, surprising the soldier enough for him to let her legs go and cry out, before letting her stumble to the ground. Her wrists were wrapped together, so she hit him across the face with both of them before turning and running.

"You bitch!" The soldier said, as more than just him went in pursuit of the young princess.

It was the commotion that caught Robb's attention, not the girl, but the blur of gold and white running towards him. The men were yelling, calling out bets on who could get the girl first. When they caught the girl, she fought back, hitting them where metal did not cover them. She screamed as two men took her shoulders, and a third grabbed her hair which hung loose around her in a light golden curtain.

"What is this?" Robb demanded walking towards them. Even from a distance, he knew the girl. He didn't know where, not until he got closer to her.

"We found the whore in the Kingslayer's tent, your grace." Said the man holding her hair as she struggled, forcing her on her knees.

"She's not a whore." Robb told them. "She's Myrcella Baratheon." He stared into her green eyes, who glared daggers at him.

She continued struggling against the three men, her breasts pressing against her dirty shift as she struggled, showing that she was not a girl anymore. "Where is my uncle? What have you done with him?" She demanded.

"Let her go." Robb said. "She will not run."

The three men let her go, and she rose to her feet slowly, with the grace her mother taught her to. She knew she was a prisoner now, but she also knew that she may be able to get away given the chance. Her mother would want her back home after this. Her mother would want her no matter what she had to do to return.

"It's been a long time, Robb Stark." She said. "I never expected to see you again. Maybe at your sisters wedding, but never like this."

"What are you doing in a war camp?" Robb asked her.

"Well, I was sleeping until your men awoke me." Myrcella said, though her voice was a bit stressed she didn't sound unpleasant. "And I'm sorry to say they did not allow me to get dressed before hitting me in the head and knocking me out. Now, where is my uncle?"

"He is being taken to his confines." Robb told her.

"And will I be given the same ones? To freeze in the elements?" She asked. "If you are to use me for ransom, that would not work in your favor."

"Why are you here, Myrcella?" He asked her.

"I believe I am still a princess, even if I do not look like one right now." She told him, though she was a small woman, she stood tall, with her shoulders back and her head high.

"Princess Myrcella, then. What are you doing here?" He asked her.

"I am your prisoner. That does not mean I have to speak." She held out her wrists to him. "I am yours."

Catelyn Stark sought Myrcella out the moment she knew of her existence, walking into a guarded tent while she was washing the mud from her skin from her chase. She even was able to get the dirt from her hair,

"How are my daughters?" Catelyn demanded, surprising Myrcella, and making her jump.

"Seven hells." She swore, a hand going to her chest. "Here I was promised that I could clean and dress in peace."

"Tell me how my daughters are, Myrcella." Catelyn told her, with the fierceness Myrcella saw in her mother when her children were involved.

Myrcella turned away from Catelyn as she finished scrubbing dirt off her hands. "Sansa is alive. Joffery isn't kind, but she is safe, for now. I don't know about Arya. I have not seen her since my father died."

"Arya isn't there? Your mother lied."

Myrcella's eyes widened-she didn't know she was saying anything that they didn't already know. She cursed herself. Too late now. She turned to face Catelyn. "She is not at Red Keep. I saw Sansa often, and Arya too, but not after my father died. I have seen Sansa since then." Myrcella didn't see a need to lie after that. She already gave everything up, might as well give the woman the truth of her daughter. "I am sorry."

"And what would your mother do to my daughter after she finds out that I have you?"

Myrcella paused, thinking of the beautiful red haired girl back at Red Keep. The girl who her brother was trying to break. "I suggest your son tells her that what Joffery does to her he will do to me. That will keep your daughter safer than anything else."

"Believe me, I will make sure that happen if they touch my daughter." Catelyn told her.

"Then you best make me bleed." Myrcella said, not frightened. "Joffery made of the Kingsguard hit her and her lip bled."

Catelyn seemed surprised that she spoke so defiantly. "I think you have more things to fear than me. Get dressed."

Cooler than ever, Myrcella walked to where one of her gowns was, and slowly put it on, thankful the laces were in the front before she pulled on her riding boots. "What are you going to do to me?"

"It is not my choice. It is Robb's." Catelyn told her. "I will only take you to him.

Myrcella's hair was wet, and dampened her dress, giving her a chill when she followed Catelyn out of the tent. "And what will he do to me?"

"He will probably be kinder to you than your brother was to his sister." Catelyn told her.

"That is not a comfort to me."

"It was not supposed to be."

"As long as my uncle is still alive I will be fine." Myrcella said, her voice calm though her heart was beating out of her chest. She wasn't wearing a corset-she wasn't able to, not in here. At least the top of her dress was tight to keep her breasts in check, but it all just felt a bit wrong.

She knew the man who held her captive. They were younger then, but they had spoken before. She was at Winterfell long before all this happened. She wanted to believe that nothing was going to happen to her. That they would still see her as the child she used to be, and now how she grew up. She knew she could easily be raped, but she didn't think she would be killed-she was too valuable. Her mother would get her back, and her Uncle Jaime. She had to.

But her mother was the one that sent her away in the first place.

"I don't want you to go, but you will be safer at Casterly Rock than you are here."

"But are you safe here?" Myrcella asked.

"As safe as I can be. I cannot leave, sweet girl, I am regent."

"Why can't I stay with you?" Myrcella asked.

Cersei frowned, as she took Myrcella's hands in hers. "Because of all the things I need, I need you to be safe, and after all this is over you will come back here."

Myrcella paused. "Are you sending me off to be married?"

"No." Cersei said. "I would not do that to you. You are not something to be traded. Not to me."

A part of Myrcella now wished that she was sent to marry someone-then she wouldn't be taken captive, even if she was to marry a stranger. Then again...she didn't know if she would be safe there either. Her mother had taught her that.

Myrcella was brought into a tent, where Northern men stood around a table. Myrcella felt as if she was on a trial. For what, she did not know. She knew she couldn't have hurt anyone. The worst any of the soldiers got from her was a bruise. She was on trial for being a princess. She was on trial for being Joffery's sister.

"What were you doing in the war camp?" Robb demanded again.

Myrcella stared at him, completely emotionless. "I told you, I was sleeping. Ask your soldiers that found me, I'm sure they'll tell you exactly how they found me."

"But why were you there?" Robb demanded.

"Seemed like a good time to go camping." Myrcella said. She didn't exactly know why she shouldn't tell him, but she already messed up about Arya not being in King's Landing. She didn't know if she was going to give anything else away. Not to the people who had held both her uncles at some time, and wanted her family dead.

"Do you really think we are not going to find out?" Asked a bearded greying man.

Myrcella stayed quiet, staring at the older man.

"Put her in a cage until she is ready to talk." Robb said. "On her own, mind you. We don't need the same treatment given to my sisters."

One of the men that stood before her, a younger one, one that Myrcella recognized as well; Theon Greyjoy. He took her by the arm, and she did not struggle as he led her out of the tent.

"May I see Jaime?" She asked as politely as she could.

"No."

"Please?" She asked. "I just want to see that he is all right. I won't try anything." She didn't even know how she could try something. She wasn't strong enough to know someone out with a single strike. She wasn't strong enough to run out of the camp with no supplies, and no protection. She had never been without a member of the Kingsguard at her side, and now the only member was in a cage.

"No."

"You know me, Theon." She said. "Do you really think I have the capabilities to cause trouble?"

He looked down at her, the princess with the big innocent green eyes. "Yes, I do."
