Prologue

Casterly Rock 282 AC, Three months before Robert's Rebellion.

Pacing around the halls of Casterly Rock that held his and his wife's chambers was a rather impatient Tywin Lannister, his daughter Cersei was off somewhere stitching and he had no idea where he dwarf son Tyrion was, not that he really cared at this moment in time. His second wife Layla Marbrand was giving birth to their child, he didn't love his current wife like the way he had loved Joanna but he did have respect for her.

However Layla had been in the birthing bed for well over 12 hours now and Tywin was certain that there was complications with the birth, after Joanna's death, Tywin didn't think he would ever marry again, but with his son and heir Jaime being named a Knight of the Kingsguard, Tywin was left with Tyrion as his heir and he would be damned if he was going to let the little monster that had killed his beloved Joanna become the next Lord of Casterly Rock and the Westerlands.

So when his vassal Damon Marbrand suggest Tywin marry his daughter Layla, a young and quite beautiful maid of six and ten, Tywin agreed with the hope of producing a more worthy heir to inherit The Rock. Tywin was suddenly pulled from his thoughts as the door to his wife's chambers opened and a young handmaiden stepped out and gave Tywin a small curtsey as Tywin could hear the cries of a baby coming from the room.

"It is done my lord, you are free to enter." The maid said before scurrying off.

The sight that greeted Tywin when he entered the room wasn't a pleasant one, his wife was sweaty, her hair sticking to her forehead, a large amount of blood staining the sheets of the bed, but in her arms was a small baby, it was a boy too.

"My lord, I must tell you that I don't expect your wife to make it through the night, she lost a lot of blood during the birth and I didn't notice any signs of her healing, I worked on it as much as I could but I'm afraid there is no more I can do." Maester Creylen said in a quiet tone before he left the room, leaving Tywin with his wife whilst some of the other maids worked around them.

"We have a son my love " Layla said with a weak and tired voice as Tywin knelt beside her and the baby's cries ceased..

"That we have my lady, he has your face." Tywin said with a ghost of a smile, the last time he had smiled properly was when Joanna was still alive. Layla too smiled as much as she could at his words.

"But he has your golden hair and green eyes, have you thought of any names husband?" Layla asked him, her attention fully focused on her baby boy.

Tywin had thought of plenty of names but he decided he would let Layla name him, it was the least he could do for her. "You should be the one to name him, I'm sure you've thought about many a name." Tywin told her and again Layla smiled.

"Hmm, I like the name Ryon, what do you think?" His wife asked him as she looked up at him.

"I like it, it is a fine name, thank you Layla." Tywin said to his before she offered him to hold their son.

"I think I'd like to rest now, do you think you could send in the maester with some milk of the poppy, if I am to pass I would like to do so peacefully and painless." Layla said with a whisper, she knew she was dying and wouldn't last the night but she had done her duty, she just wished she could watch her son grow up into a man.

"I will see to it my lady, I am sorry this has happened to you, if you are to pass, would you prefer to be buried here or back at Ashemark?" Tywin asked his wife, it was something he was willing to arrange, after all Layla had given him a possible new heir to replace Tyrion if he couldn't get Jaime back from the Kingsguard.

"I'd like to be buried back at Ashemark if it isn't to cause too much trouble." Layla told him before her eye's slowly closed.

"It shall be done my lady." Tywin said quietly before leaving the room to find the maester,little Ryon Lannister in his arms, the possible future of house Lannister in his arms.

Hi, thanks for reading, this is an idea i've had in my head for a while, I've always wanted to write some asoiaf fan fiction but never really had the time.

If you could let me know what you thought of it and where I can improve that would be great, also I don't have a beta so sorry for any mistakes and I hope I can get this as accurate as possible, also Layla was an oc too just in case anyone was wondering.

And if you have any ideas you'd like to see in this let me know, I should warn you as well that Ryon won't be perfect, he will have his flaws and he's going to be raised by Tywin so don't expect him to be the most kindhearted of people.
