My name is Gerold Lannister, I died in the real world and got Sent to Game of Thrones to fuck everything up, I was presently speaking six years old, and already made House Lannister richer with my knowledge of technology far outstripping this world's.

(Tywin Lannister POV)
----------------------‐------------------
Tywin was often said to only smile when Joanna was near, but the revolutionary things his son Gerold came up with were making House Lannister Wealthier and stronger still, and that always brought a smile to his face.
The boy came up with new Drinks that kicked like a stubborn mule when you swallowed. Designed new Ships to increase Lannisport's Naval Superiority and defense. Designed new machines of war that put old technologies such as The Ladders and Battering rams to shame.
His mind was brilliant but so too was his Sword arm, skilled with a blade unlike anything Tywin had ever seen before or dared to dream of. His son had eschewed a Broadsword in favor of a Longer curved Sword with a bent handle.
This sword was revolutionary, the bent grip allowed for more power to be exercised when swung or swept and the Curve of the blade made it strange to fight with, but stranger still to fight against, even stranger with the bent grips. Gerold was a Prodigy, his brilliant young mind was what Tywin attributed mostly towards Joanna.
Gerold had already asked him to rebuild Castamere and Tarbeck Hall so that his future siblings or sons may have somewhere to call their own, and so that Gerold might gain experience before becoming his successor.
Tywin had never been more proud in his life. This son of his was something else entirely....

(Joanna Lannister POV)
----------------------‐------------------
Joanna watched from afar as her Gerold was busy practicing his Swordsmanship, fighting his Uncles Tygett, Gerion, and Kevan to a standstill even as his Lionsguard watched their Lord's three Generals and uncles losing badly.
Gerold wore a blindfold, he had been training in using sound to survive in the event he was blinded temporarily in battle. It was humiliating for the three to not be able to touch Gerold, even blindfolded, he fought with all his senses. Sight, Smell, and hearing, but it was when one of those was blinded that Joanna noted he was at his most dangerous.
Joanna adored Gerold, he was a perfect amalgamation of her and Tywin.
Joanna watched as Gerion was disarmed and Tygett kicked to the dirt, leaving only Kevan still standing sword in hand.
''That's enough!'' Tywin's voice cut through and Joanna noticed Gerion and Tygett exchanging Coin with the Lionsguard, With Tygett being the apparent losing side.
''Let this be a lesson, even blinded a Lion is a formidable foe!'' Gerold says before looking at his father. ''But an Arrogant Lion is too easily felled, physically blind or not, arrogance will blind you martially.'' At this Joanna smiles, he is confident but not arrogant. The perfect Lannister.....

(Gerold Lannister POV)

''You fought well my son, you have long since surpassed me. And this is good, Because now I must return to the Capital, Aerys needs me.'' Says Tywin.
''He needs a therapist more.'' Says Gerold, having long since explained that little joke to his father. Tywin barks out a laugh, before ruffling his Hair affectionately.
''Take care of your mother and inform me when you believe her pregnancy nears it's end.'' Tywin instructs.
''Yes Father, so long as you abide my the Wager me and Uncle Gerion set.'' Durran says, having bet considerably on the fact Cersei and Jaime would be born next. Gerion bet Tywin a Million Gold Dragons, while Gerold bet an undisclosed future favor to be called in at any any time, as his prize, which he planned to use to get House Lannister into the Rebellion covertly.
He took special joy in getting Tywin smile. See in his old life he had a father and mother who dumped his infantile ass on her parents, best thing they ever did, now his gramps? Didn't particularly like Charles Dance, but his personality as Tywin was so similar to his grandfather that getting a reaction like that out of Tywin was a way to remember his old life without being drowned in sorrow at not having his old life or his family.
Gerold Lannister wanted to create a Dynasty the likes of which will surpass Tywin's own expectations and he knows how to get just that...This was gonna be oh so very Fun...
This plus Black Storm will be part of a prequel series, not sure if it's gonna be strictly a two story prequel sequel series or a few more, also no harems for this or Black Storm anymore
