Tanya the Evil (Youjo Senki) x HOTD / Fire & Blood. Tanya is reborn in her third life as the daughter of Viserys Targaryen and Aemma Arryn. The story prior to the butterfly effects Tanya's existence brings in, will be a mixture of the the HBO House of the Dragon timeline and the the Fire & Blood book timeline, with some minor alterations to make continuity make sense. Book plot points will be introduced and the story will borrow from both.
A Young Woman's Inevitable Dance of the Dragons 
is a crossover fanfiction between The Saga of Tanya the Evil and A Song of Ice and Fire by Failninja, who also wrote A Young Girl's Game of Thrones.
This fanfiction contains examples of:
- Abusive Parent: Otto sees his daughter as nothing but a pawn for his ambitions and doesn't care that he's driven her to extreme paranoia over the non-existent threat of Rhaenyra executing her and her children upon her ascension to the throne nor does he care about the problems he's been putting on her plate since he made her marry Viserys.
- Adaptational Nice Guy:
- Thanks to having a consistent and competent parental figure in his life, Aegon is almost completely devoid of all of the behavioral problems that made him a Hate Sink in the show. He still has a temper, but he actively attempts to keep it under control.
- Zigzagged with Aemond. He’s still as prideful, haughty, and mean as he is in canon, and as he avoids the eye-for-an-eye incident, he doesn’t experience his mother fiercely defending him; causing him to look down on her. But he greatly admires and respects Elaena, and tries to emulate her politeness and diplomacy. It’s also hinted he may be developing a sister-complex because of her.
- Always Second Best: Aegon is regularly surpassed by Aemond in many things, from their studies to their training, despite being the older brother. It’s only due to Elaena's teachings that it's not affecting him worse than it would have.
- Ambiguous Situation: Unlike Failninja’s other crossover, this story is told entirely from the perspective of the people around Tanya, rather than Tanya’s herself. It’s thus an open question just how much she truly understands the familial-divisions that exist around her, and can potentially lead towards civil war, and her exact views on individual people; or if she’s once again horribly misjudging things due to her classic miscommunication and assumption problems.
- It’s also heavily implied Elaena is using magic, but how much she has, and what precisely she can do with it, especially in combination with a dragon, is also never elaborated.
- Big, Screwed-Up Family: The Targaryens, unsurprisingly. Half of the family split along matrilineal lines is plotting to kill the other and vice versa, while King Viserys remains oblivious to the brewing catastrophe.
- The Chessmaster: It’s implied Elaena is this, as she strives to endear herself to as many members of the family as possible, so that both factions view her favorably, and is using her close relationship with Viserys to enact her own agenda.
- Dramatic Irony: Almost no one realizes that Elaena is more interested in maintaining the peace within her family and is the "Dark Storm" everyone credits Laenor for, and is a de-facto Black only because she respects the rules of obeying a king’s explicit command, and on the condition that Rhaenyra abstains from kinslaying.
- Thanks to Elaena’s influence over Viserys, her refusal to solidly declare for any faction through their colors, and willingness to pursue policies that would be genuinely beneficial to House Velaryon, while not being as easily swayed as her father, Otto Hightower not only comes to view Elaena as a Black, but believes Rhaenyra is the true brains behind everything Elaena does.
- Conversely, Daemon has no idea that Elaena is the reason Viserys was convinced to let him return to King's Landing, and believes Elaena is a Green because Otto is (begrudgingly) working with Elaena on policy compromises with Elaena's efforts to retain concessions beneficial to the Blacks being lost on him. This is on top of him constantly antagonizing Elaena who, it must be restated, is already committed to defending Rhaenyra's right to the throne (the irony only redoubles when he plans for Laenor to dispatch Elaena in the event of war).
- Evil Is Petty: After Elaena judges Cole to have defeated Daemon in their tilt, by which she looked at their lance placement, her uncle decides that he needs to avenge this affront to his pride by physically harming his young niece in the celebratory feast. It is also implied that he used his contacts in the city watch to spread salacious rumors about her.
- Fake Ultimate Hero: Because Elaena prefers that no one knows that she joined the war against the Triarchy, Laenor is credited with bringing the Stepstones to heel, slaughtering the Triarchy's troops by the thousands and bringing their leader's head to the gates of Tyrosh. For this, he is dubbed "The Dark Storm".
- The Hedonist: Rhaenyra primarily concerns herself with the lover's circle she amassed for herself, which involves Harwin Strong, her uncle Daemon, and her cousin Laena.
- How They Treat The Help: Elaena is beloved by the smallfolk of King's Landing. This started from small acts like generally treating them with human decency, to saving a handmaid from physical harm and royal reprisal when a young Aegon threw a tantrum, to regularly patronizing the works of the city's artisans and networking with them, up to giving them grand opportunities for upward mobility with the Knights of Victory and offering the services of the Dragon Bank to wealthier merchants and guilds. She became so well-regarded that when goldcloaks started spreading rumors that one of her Knights of Victory took her maidenhead, angry citizens murdered them for daring to slander her virtue.
- Jurisdiction Friction: The establishment of the Dragon Bank, while an overall net positive for the Seven Kingdoms, is seen by some lords as overstepping their authority when Viserys grants its creditors and debtors the right of appeal.
- The Medic: Elaena secretly serves as this for her family, as she regularly mitigates Viserys’ illness so he doesn’t deteriorate as quickly as he did in canon, and always attends every time a family member goes into labor to ensure both mother and child survive.
- Mistaken for Gay: It’s implied Elaena believes Criston Cole’s brutal beating of Joffery during a tournament is because he’s in love with Laenor and jealous of their relationship.
- Mythology Gag: After false rumors of her having trysts like Rhaenyra, are discovered, Elaena uses the same method as Princess Myrcella did in A Young Girl's Game of Thrones, and Tyrion did in canon, by telling the servants around her different versions of a story to try to discover The Mole. It fails this time simply because her Nice to the Waiter tendencies results in all the maids and servants around her being so utterly loyal, they’d snub heir to the throne to her face rather than reveal anything.
- Not Helping Your Case: Rhaenyra, despite being the designated heir, faces an uphill battle to maintain legitimacy as future monarch, yet she constantly undermines her own position through extramarital affairs and offspring, lack of interest and knowledge in statecraft, and her association with Daemon.
- Elaena inadvertently does this by trying to convince Viserys to eat healthier in order to combat his illness. Because she regularly and secretly uses her magic to heal him, Viserys is free to indulge in any food he wants, and not feel any worse for it. Elaena comes to realize this when she discovers Viserys has been going behind her back in regards to his eating habits, and cuts off her magical healing till Viserys suffers the consequences long enough to agree to her diet method.
- One-Man Army: Every dragon rider is this, but Elaena and her dragon Viktoriya take it even further despite their youth and relative small size, due to Elaena’s experience with war and aerial combat, and possibly magical enhancements. So much so, she near single-handily destroys the entire army of the Triarchy and Dorne.
- Parental Neglect:
- Alicent is a largely absent mother to all of her children, paying no attention to their needs and wants and is only concerned with how they can advance the Green cause.
- Save for Elaena, with whom he speaks and dines with nearly every day, Viserys is barely in any of his children's lives.
- Daemon is displeased that his (legitimate) firstborn son is malformed, opts to name him Maegor, after which he ignores him entirely.
- Parental Substitute: Elaena takes care of her half-siblings by Alicent, seeing to their education and well-being even more than their own mother, leading to them seeing her as the most important figure in their lives.
- Poor Communication Kills: A good amount of hostilities is driven by the fact that malicious intent is assumed as the default when compromise happens, or a coincidence of bad luck to one's allies, or information is otherwise omitted and the intentions never known.
- Royal Brat: Rhaenyra is this as in canon, being more interested in pursuing her own pleasures than in running a kingdom, while still feeling entitled to the throne. It gets notably averted with all of Alicent’s children, thanks to Elaena’s influence as their parent figure.
- Royal Inbreeding: A Valyrian tradition that Rhaenyra, Daemon and Laena are actively practicing while Aegon and Helaena are matched to do so once they come of age. It is notable that Elaena is averse to this practice (thanks to her knowledge about the problems of inbreeding), and insists on finding a husband outside the family, much to her brothers' disappointment, though Viserys has told her that he will have her marry Aemond if she is unable to select a suitable man when she goes on tour around the kingdoms.
- Secret-Keeper: Laenor keeps Elaena's involvement in the pacification of the Stepstones to himself and is tormented by that fact enough that he eventually confides this in Joffrey.
- Seers: Helaena has visions of events from both the canonical Dance of the Dragons and of Tanya's time in the Great War.
- Spared by the Adaptation:
- Thanks to Elaena's intervention, Joffrey Lonmouth survives his tilt with Criston Cole. He has to contend with being crippled for the remainder of his life, however.
- Harwin Strong survives his canonical death at Harrenhal, waking up and escaping before the fires should have consumed him.
- Again thanks to Elaena's healing magic (though nobody knows it) both Laena and her son with Daemon survive, where in canon neither survived long after the birth.
- Weak, but Skilled: Elaena and Viktoriya are both younger and smaller than many of her fellow dragonriders and dragons respectively. However, thanks to her military experience from her previous life, and possibly magically boosting her dragon’s abilities, Elaena has such exceptional aerial combat skills that, under the guise of the Dark Storm, she inflicted such catastrophic damage against Dorne and the Triarchy as to be compared to, if not surpassing, Aegon the Conqueror.
- What Would X Do?: Aemond bases his decisions and general approach to life on Elaena's teachings and considers how she might resolve some of the situations he finds himself in.
- With Us or Against Us: Both Otto and Daemon have this attitude when evaluating people, and both of them to believe that Elaena is siding with the other faction because her actions support family members regardless if they're Black or Green.
- Would Hurt a Child: Daemon feigns drunkenness to bruise Elaena's arm at a feast, and later he tries to buzz her during a dragon flight to give her a scare. He also plans to have her killed once the impending civil war kicks off and Otto intends to do the same.
