Chapter One

…..

Hoster Tully has always known and expected for his daughters to be great. He is right in a way. His beautiful eldest, Catelyn Stark is now wife to the Lord Eddard Stark of Winterfell, and her heirs would be one with Tully Blood on the North, the largest region of Westeros. His second daughter is wedded to Jon Arryn, Lord of the Vale and Hand of the King.

Sure she had been a disappointment before, but now that she remembered her duty to family and country, she also made him proud. Now all that's needed for her is to bear an heir worthy of both Arryn and Tully bloodline. A bloodline that will rule the Vale and the Eyrie for centuries to come. Thinking about it alone in his solar makes Hoster over the moon. After all that haggling, fighting, quarrelling and breaking deals under the table, the time of the Tullys' of Riverrun have come in history of the Seven Kingdoms.

Of course not everything is well and off. His brother remains a widower and taking pleasure guarding the Bloody Gate as its knight. As far as Hoster is concerned, the Blackfish despite his reputation as a warrior is no better than a disappointment for being the bloody guard of a rather decaying gatehouse. He should be trying his damnest to improve House Tully's progress and reputation instead of running around with a sword in his hip. Any fool with a sword can do what he does.

Don't get him started on his son, Edmure also. The boy is nineteen already and the moron doesn't have a lick of sense in him. Sure he attends his lessons and is rather rudimentary with his skills with the sword. He is shit on the bow though and don't get him started on his riding skills. All in all, he is shaping to be a poorly replacement Lord of Riverrun in the event that something bad happen to Hoster. Normally Hoster would wait until some of Catelyn or Lysa's second or third sons come of age to check on their growth before deciding who to name the next Lord of Riverrun. There is however one issue.

Disappointed for the rather abysmal performance of his son at one of the new King Robert's tourneys (being unseated by a newly minted Knight who looks half drunk), Hoster in a fit of despair and shame got himself rather drunk and lost his way to one of the brothels at King's Landing. Lo and behold, nine months later and said whore appeared at his doorstep in the middle of the night at Riverrun carrying a bundle in linen before leaving.

And that is how Hoster Tully got himself a third daughter, Deliana Tully in his old age. Hoster would wonder himself why in the world did he not threw the bastard girl to the moat the very second he got her. Normally, he would do so. Bastards were born of sin and he just won a war. The last thing he needed was for his name to be tainted. Worse for some reason he cannot fathom, he even called the favor from Robert Baratheon about helping him win the war in order to fully legitimize the bastard girl the next morning he got her. Part of Hoster wondered if he was bewitched back then before kicking himself for thinking such nonsense. Magic is not real in this part of the world; only stories and legends from a bygone age. Still what's done is done and Deliana Rivers became Deliana Tully, in a fortnight.

And that is why Hoster Tully is thinking so much right now. Deliana in every way is not normal. Being able to read and write at the tender age of three and able to recite the entire Book of Lords of Riverrun without missing what House which Lord belonged to. It impressed the current Maester so much that he even sent a recommendation to the Citadel, a thing extremely unheard of since only boys are allowed to be Maesters. Worse, she was only three. Hoster of course thought that the Citadel would refuse due to those reasons alone but lo and behold, they accepted and his bastard daughter left for two years there to be "tested" about her talents. He had expected that he would see her again in a month but once more she achieved the impossible for not only being able to earn the right to study there, but also got private access to the hidden halls that were only reserved for Arch-maesters.

Hoster was bewildered as she read the letter with the Citadel seal on it. Not only did she got the former Arch-Maester of Mathematics, Science, Agriculture, and Philosophy kicked off by beating them in the three day session debates, she also introduced enough ideas that changed the Citadel thinking that women "might" also contribute something to the wellspring of knowledge.

When she returned after two years, Hoster was faced not with a child but a mature girl.

She literally commandeered nearly every aspect of running the business sector of the Riverlands and strong armed the leadership role of the castle from him. These days all Hoster does is sit on his solar or at the banquet hall thinking, eating and meeting the other Lords of Riverrun to reminisce old times as his daughter do whatever she wants.

A large part of Hoster fervently believes that the heir that he has been seeking out is literally in front of him and he needs not search any further. There is another part of him however that also refuses to accept this truth no matter what he does. History of Westeros had proven time and time again why it is a bad idea for women to lead. Worse still; a bastard being named a successor for a Lord Paramount. Yes, for now he will withhold his judgement and Edmure will be his heir. There is still time for his son to pull his head out of the gutter (He hopes).

…

If somebody would tell Harry Potter, wizard extraordinaire, the Man-who-Conquered, the Legendary Auror that brought down budding dark lords, Quidditch Three time World Champion, Veela's Choice, Leader of the Magical Resistance, and Bringer of Peace of Two Worlds, that he would be bodily transported out of his rather luxurious lifestyle of a pseudo billionaire into this Medieval World where there is even a lack of proper restroom, he might have willingly committed by Avada Kedavra at Voldemort's hand twice.

He had been lounging on his rather exquisite Jaccuzi bathtub enjoying the pleasures of life after ending the war between muggle and magical with a blood treaty when he was summarily pulled out of his timeline, into a tube and only got a few seconds to be given by Death how to be reborn in a new life: A.) Old Man trapped in a tree with roots growing inside him (Oh fuck no!) or B.) Baby girl with a future having a hot body (while drool worthy, he can't help the double take at the gender switch option).

Of course Death being the asshole it is, the moment it finished speaking, it had consumed nearly the entirety of the time with his explanation about how this world needs a savior and he was his best option. Thus Harry Potter the Great only had a split second to decide between "trapped old man" and "soon to be hot girl".

He had literally swallowed his pride by choosing the latter. That means bye-bye to his precious down below.

Of course Death as usual is a moron and instead of giving him a highborn life, he was born as a bastard and from a whore of all people. He might had accepted being the dally result of his Lord Father Fish boy and a noblewoman; but a whore? Seriously? If being a bastard at this new prejudiced world was already a bad thing, being born a bastard of a whore was much much worse.

Emergency situations need emergency action.

Thus without preamble and despite the fact that his magic was wild due to him being babyfide, he had literally thrown the most sharp compulsion at Hoster Tully's head in order to prevent him from making Harry an impromptu swim after her mother gave her to her father. He had no wish to know what Moat Water tastes like, thank you very much.

Thus begun Harry's life in Riverrun as Delianah Tully. He had to give himself brownie points for compulsing Hoster Tully again into naming him into his Skyrim Avatar's name. Might not be as scary as Voldemort's name but hey, he's a girl and going to be a hot one if Death's future picture might be taken into account.

First things first though as far as Harry is concerned; what he or in this case now, a she needs is a power base. If she was born as a Highborn, it might not have been a problem being the daughter of the Lord of Riverrun, but she was a basstard and everyone knows it. Thus once more compulsion is the key and her father went running to Robert Baratheon to legitimize her. Of course she knows by more mind reading that this move of hers was barely a step forward. A legitimized bastard was still barely a step up by a bastard. No, what she needed was to build her name that the other lords and ladies of Westeros might point higher than their stigma of bastardry.

It's not that hard for her as far as she's concerned. Her brother, the heir Edmure Tully was a fool and lackwit with zero ambition. It would not even be an effort for her to overtake him.

Thus begun Delianah Tully's road to greatness.

The Lords of Westeros might be Lords now but they all started on something. It is their repute and achievement that gave them their titles and names. Delianah would do the same. She will build her name so high that even the great Aegon Targaryen's name would be overshadowed by hers.

That is why at once she must put her stance to that of being invaluable. Easy; the old adage of knowledge is power applies here perfectly. After shamelessly mind reading every single being that lived here at Riverrun while still being babyfide; Delianah almost cackled in glee at the information she had gleamed.

Knowledge was lacking in this world. Thousands of years and the people barely made any advancement into anything, living like traditional peons, repeating the same song again and again. Maesters, Guardians of Knowledge were the only ones that can even be put into something more than being literate. The Highborn themselves were barely a step up from being learned and the smallfolk did not even know how to read and write.

Thus Delianah had her first goal. She would soar in the realms of knowledge and be something that this world had never seen.

It was no hard effort for her to impress the Maester of Riverrun at the age of three when she was learning her letters while raised as the child of Hoster Tully alongside some of the Fostered heirs here at Riverrun. She had to paint the image of her progressing so far as to even memorizing the Book of Lords in one go (Of course it's not that hard answering his questions when she can read the answers at his brain like an open book). With a mild confundus charm, she was able to influence the Maester enough to put her as a candidate to visit Oldtown despite her being a girl (she had to place the confundus due to his reluctance of her gender which no amount of knowledge can change).

Thus after literally enchanting the letters with the most powerful rune activated compulsion charms that react when the letters were opened. The letters were sent. She had to make sure to add those in order to bamboozle the old farts there. Some of the might have strong minds to resist the basic influencing charm and Delianah was not taking any chances of them saying no.

It worked like magic(no pun intended). The reply from the Citadel was quick and precise and a month after Delianah sent those letters, she was on her way to Oldtown to be "tested" about her gift of knowledge.

Of course there are two reasons as to why Delianah is going on the so-called knowledge trove of Westeros other than proving her mettle of being a once in a thousand year genius:

First is the simple fact that she wanted to avoid the two year "Babyfide" regimen of Westerosi ladies by Septas slowly molding their brains that they be nothing more than glorified housewives and broodmares. Delianah had heard enough simply by reading minds thank you very much.

Second is she wanted to know what in the world happened to magic in this world. It felt as if someone siphoned it off leaving literally nothing. Long and bitter experience as Harry Potter the Great, made him more than aware of the simple fact that all legends had an ingrain of truth in them. Westeros had more than one legend supporting each other. The truth was hidden and he wanted to know, why.

On a more personal matter at hand, he simply wanted to read books and enjoy the next two years rather than listening to the repetition as to how beautiful and wonderful it is to marry a knight and be all submissive and stuff. Plus he also wanted to try out his hand in writing a book (despite being abysmal about doing it); and she also needs time to get acquainted with her new gender and all the challenges it brings (Vanishing shit (In secret) is also much easier than using the privy).

Long story short, he or rather she literally turned the Oldtown Maesters upside down. She answered every question they had for her when she first arrived. She beat them at their debates, discussing ideas and philosophies that made many of them cross-eyed. She declared to them simple basic facts of science, mathematics, philosophy and the power of language and religion. Gravity, basic algebra, geometry, physics, statistics, words of wisdom(heavily plagiarized), Earth Science, history lessons and socialism she discussed in depth to them during her first few weeks. Simple subjects taught as general lessons by schools back home.

The result was six Arch Maesters kicked out, a couple more demoted, a horde of fans and admirers from the acolytes, and a unique once in a time only invitation from the Citadel granting her free access of learning to its halls despite having tits and a cunt (Sexist bastards). Thus for the next two years Delianah stayed at Oldtown basking on the admiration of hers truly from everyone there. Many in fact were grumbling that she would not be given a chance to be part of the Maesters. She however was given the chance to forge her chain links as proof of her stay there.

She was six years old when she left (with many a plead from the Citadel for her to stay) for her home back at Riverrun. To say that the reception she got when she arrived was a mixed one.

On one hand, some of the more pragmatic Riverlords were astonished and were more welcoming to her presence seeing the benefits of having a powerful force of nature at their good graces. The more traditional at the opposite side were wary of her. The history of bastards rising above their stations giving off warning bells inside their heads. The story of the Blackfyre Rebellion after all was a well known sample of bastards taking something that didn't belong to them.

Her father however was over the moon for her about it. Hoster might be an opportunistic bastard, but he had a good eye when locating someone worth noticing. Despite the fucker originally planning to ditch her at dirty moat water, she needed him at the time being.

Thus with her newfound renown and reputation, plus the shining credentials (forged links always on display cough2x); it was not hard of Delianah to take over the finances and managing of Riverrun. Normally it is Edmure's duty running Riverrun especially with Hoster getting on in age. However the supposed to be heir was more concerned with going out chasing girls and hanging out with the other rambunctious young lords. Delianah didn't even had to use magic to convince the man-child to run off to "enjoy" his time. Of course many protested by her sudden taking over of power. None however wanted to be in the place of being the glorified manager and accountant. Thus it falls to her and only her.

Now here she is looking over the finances and the stuff that makes Riverrun run. To say the least, Delianah isn't happy.

Other than the fact that the castle lacked a sewage system (she really misses toilets). Riverrun might be a step up from the hovel of the Medieval ages but emphasis though on Medieval Ages. Born and bred on modern society, Delianah wants her old comforts back. Sure she might not have all of them but she wants most of them back, especially the food. Food in Westeros is bland and lacks creativity, even for the Highlords. Fish tastes like fish, meat tastes like meat, fruit to fruit and that's it. She can't take it any more!

Grumbling to herself, she uses her six year old small hands to open the ledgers that account everything of the Riverlands. To say the least, she isn't pleased. Riverrun is literally the second poorest house of Westeros next only to the Northerners in their frigid icy homes. Being the battlefield of the warring houses throughout the centuries had done no favors to the land and the people. Add the fact that House Tully has literally zero renown other than the weird fish sigil in the Seven Kingdoms. The only reason they're not the first is because like the Reach, the Riverlands also have farmlands whose produce they sell mostly North. Other than that though, and the fish, they have nothing to be proud of.

The Northerners are well-known for their hardness, they are respected as warriors despite being called barbarians. The Westlanders are rich, period. The Reachers are the lauded knights, the heart of Chivalry. The Stormlanders are the best seamen in Westeros, second only to the iron-born and well-known for their loyalty and quick temper. The Crownlanders are the professional army of the royal throne and its levies. The Dornish have never been conquered. The Valemen are the best knights in the realm.

The Riverlanders on the other hand have…..fish. (Chibby scream!)

The hold of the Paramount is less than ideal with many houses stronger than it literally ignoring what generations of Lord Tullys' command them to do. All in all it is a slugfest mashup of a community each fighting for his own with literally no true loyalty to its Paramount Lord. The only reason they doesn't yet is because the Tullys' has the backing of the crown, by the Targaryens before and now by the Baratheons.

Closing the book in anger, Delianah stomps towards the windows where she can see the entirety of the Riverlands. Yes, a clean slate and Harry Potter the Great would make this middle-aged hovel formed country to his or this case her new playground.

Author's Note: Harry X GOT is always Harry of the North as a Stark or the West as a Lannister. I wanted to try something else. Meet harry as a Tully, and oh boy. He or she will bring something new to this Game of Thrones.
