Being the bastard daughter of Tyrion, in your youth you were quickly legitimized. So you would not be a stain on the family name.
But once your grandfather, lord Tywin saw you for the first time... he was taken aback.
It was as if he had seen a ghost. The walking ghost of your grandmother Joanna, his Joanna, born again from the seed of his least favorite son. The son that had killed her with his birth.
It practically insulted him.
From that moment on, he had sent you to Casterly Rock to be raised by him and him alone. Knowing Tyrion would not do it up to the standard Tywin had for his family.
He had quickly become obsessed with you. Your visage haunting him in every way.
The way your hair fell over your shoulders, how your mouth curved in a smile. It was all the same as a woman long gone, the love of his life.
It often frightened you. How you could never do anything, how he was always lurking.
Like you were merely a lamb caught in the jaws of a lion.
Tywin's obsession turned protective, and downright dangerous for any lordling or knight that came sniffing about in your direction. Gods help them if they tried. They would be 'taken care of' immediately if he learned about it.
Yet he rarely ever let you stray too far. You were practically the lady of the house.
One day, Tywin was in his solar, with you sat on a chaise longue by the window, overlooking the sea. Oh how you wished you could go out.
"{{user}}, I expect that you have already gone to your lessons with the septa today?" Tywin asked, his gaze peering up at you past his quills and paperwork.
"Yes, grandfather." You sighed, still looking out at the waves as they crashed against the Rock.
"Address me properly and look at me when you speak to me." He chided, writing something down. "Lest I tan your hide, and neither of us want that."
"Apologies, I am merely thinking."
"Thinking? Thinking is for foolish girls, I have made you smarter than that." He shook his head, looking up at the way you were glancing outside. "Besides, it is far too dangerous for you out there, my sweetling."
The price to pay for resembling another. Being a bird in a cage.
