A/N Hi! So this is my first Game of Thrones Fanfiction :) I got the idea from reading theories about Cersei's first child with Robert before her and Jamie started having kids. The first chapter is kind of short but I just wanted to see if this concept was any good. Let me know what you think and if you like it I'll continue. Thanks :D-IlyriaMaslan

"Bite down on the silk, your grace. It will ease the pain." The midwife knelt in front of her propped legs, watching for the crown of the infants head.

"I cannot, Lyrindise. My jaw aches from the cursed cloth!" Cersei cried out, twisting in agony and filling the hollow room with her screams. Her breathing became more labored as the birth progressed.

"It should not be too much longer, your grace." Lyrindises voice changed from a comforting lull to a sharp seriousness, "You must push, Cersei." Her brother, Jamie had prompted her, squeezing as close to her side as he could get. The midwives, Casslyn and Harma, knelt on either side holding her weak hands and encouraging her to continue. She gave her strongest might and collapsed down, a weeping broken mess. They continued to urge the nearly unconscious queen until they were met by a cry much higher pitched cry than hers.

"It is a son!" Lyrindise rejoiced and laid the crying child on her mothers chest.

"First child of mine." Cersei weakly cooed to the infant as the midwives gathered round to lay eyes on the Prince. He looked exactly like Robert. If this did not win the kings affections then he had no heart. Moments later the queen jolted violently, letting out another loud scream and clutching the boy tightly to her chest

"Your majesty, what is it?" Harma asked in a concerned tone. She did not reply, she only let out agonizing screams as she did minutes ago.

"Casslyn take the Prince." Lyrindise spat urgently, opening the queens legs again and dropping her jaw. "Another child!" Jamie stared at Lyrindise with utter shock and rushed to the hand that Casslyn had left un held. Harma took the queens other hand and helped her to push again. Her screams of pain echoed throughout the room again as she dedicated her last effort to delivering the unexpected child. With one large push another cry was heard.

"A daughter, your grace." Lyrindises smile was large at the gift as she placed the baby upon her chest. Cersei looked down at her newborn daughter with surprise. The brown was prominent in her hair, a Baratheon trait, but her eyes were as grey as the Northerners. 'Let us hope your child does not resemble the person you hate most.' She recalled the statement her brother, Tyrion had taunted her with upon the announcement of her pregnancy. How could he have been so right? As she looked into the face of the daughter she had bore, she saw the face of her husbands only love. The woman whose name he had cried out during her children's conception. Her worst enemy. The room was silent as they watched her interaction with the child. It was not nurturing, though she did not turn her away. She simply stared at the infant, who stared back. This had to have been a curse set upon her by a witch. Or perhaps it was the Gods sick way of exploiting her indiscretions with her own twin. 'Jamie..' She thought with hurt, only now seeing that she had given birth the exact way her mother had to them. Jamie had been born clung to Cersei's heel and they grew together as lovers, knowing nothing but one another's touch. Though it was the truest love she had known, she didn't wish for her children to lead the same life. She had longed to love Robert the way she had known love with Jamie but she would never be Lyanna Stark, The She-Wolf. That realization caused a dry lump in her throat as she looked upon the face of a woman deceased in her own baby.

"What shall you name your son, sweet sister?" Jamie had returned to her side with the sleeping prince in tow.

"Sylas Baratheon, First of his name." She dubbed her son with a small smile, gazing upon the sight of her brother rocking the small boy.

"And your darling daughter? A princess should not be nameless." His chuckle invaded her now darkened thoughts. It pained her but she knew there was no name in the realm that suited this girl besides the one she hated most and no other name Robert would call her. She did not see her 'darling daughter' as the product of Robert and herself, but as the child Robert and Lyanna might have bore had she lived. Jamie saw the disdain in her eyes and instructed the handmaidens to begin preparation of sweets and bread for the queen.

"Lyanna.." The name lingered on her tongue like the taste from a bitter cup of wine. This girl did not belong to her and she couldn't pretend to show her love until she was married off. The only other option she could imagine could only be entrusted to one person. It was a horrible deed to task upon her brother but what other choice did she have? Was she to live with the constant reminder that the one person with whom who daughter shared resemblance had managed to steal the heart of not only Robert but Rhaegar as well? One had killed for her and one had lost his life with her in mind. It didn't seem fair. Her eyes met Jamie's and it seemed in almost an instant that he knew what his sister wanted him to do.

"Are you so jaded that you cannot show your own daughter mercy simply because of her resemblance to the Stark girl?" This had been the first time that he could recall being truly angered by Cersei. He kept his voice to a low growl directed towards her.

"Robert would fall for his own daughter at first glance. It is a greater mercy to rid her of this life than allow her to live under beliefs of false love." Her raspy voice matched the tone of her brothers voice. She took Sylas from Jamie's grasp and motioned to the little girl. He hesitated and looked into Cersei's unchanging eyes for any sign of love before bringing the infant into his embrace. He took in her overwhelming facial features and sighed sadly, rising to his feet and taking one last menacing look around the room. His eyes rested on the only 3 maidens that had been present.

"I suppose they shall meet the same fate?" Cersei had not yet thought of the maidens who had witnessed and aided in the birth. She merely nodded her head once and continued to coddle the baby boy in her arms before speaking in their directions, "Harma, might you take Prince Sylas to be bathed? I will keep hold of Princess.. Mercy. I do not wish to be away from both at the same time." Her smile was hardly genuine, but it was believable considering her current state. Harma lifted Sylas gently into her arms, turning towards the bath chamber door and closing the door behind her.

"You may take their lives here," She coarsely whispered looking at the other women's backs, "But not hers. You know the secret doors to the outside from here. Take her to the deep woods with Harma and Sylas. Make it seem as if she died trying to steal the prince and hide the girl. The king will not know of her existence." The statement stunned Jamie. She had wished the death of her child but could not bear witness to it? This assured him that she did harbor love for little Mercy and it only hurt him more. He set her back on Cerseis chest and inched towards the girls. With a quick motion he unsheathed his blade, Sliding it effortlessly across Lyrindise and Casslyns throats before they could alert the guards that stood outside in the halls. Cersei watched with a slight sadness as their bodies slumped to the ground. Lyrindise had been her handmaiden since birth and she knew she would never be given another such as her. Jamie turned on his heel to face her and knelt down to retrieve his niece.

"Tyrion tore mother in half and was born with a face father couldn't bear to look at..but he did not send our brother to his death." She flinched at the piercing words as her brother disappeared with her daughter.
