One possible plotline could be their first encounter. Maybe Rhaegar, with his noble and somewhat mysterious air, meets Fem Harry in a forest. Their initial meeting might be filled with confusion as they come from different worlds but are drawn to each other's unique qualities.
A third plotline could be about a love triangle. Perhaps there is another character who is also in love with Fem Harry, and Rhaegar has to compete for her affection. This would add a lot of drama and tension to the story, exploring themes of jealousy and true love.
Perhaps in the fanfiction, Fem Harry Potter is a descendant of an ancient Targaryen who was sent to the world of Harry Potter for safety. When she returns to the world of Westeros, she meets Rhaegar. They could bond over their shared sense of duty. Rhaegar might be intrigued by her different kind of magic and her unique perspective on the world, and together they could work towards a more just Westeros.
One common theme is the clash of two different worlds. Harry comes from a world of magic with certain values and norms, while the Targaryen world in Westeros has its own set of complex politics and traditions. Their marriage often serves as a way to bridge these two worlds.
Rhaegar Targaryen is often depicted as a noble and chivalrous character. He is known for his good looks and his skill in combat and leadership. He has a certain air of mystery around him, which makes him all the more appealing.
They might have a love - hate relationship at first. Fem Harry Potter could be seen as an outsider by Rhaegar, and he might be suspicious of her magic. But as they get to know each other, the hate turns into love. Harry could be attracted to Rhaegar's noble and chivalrous nature, while Rhaegar could be drawn to Harry's strength and unique abilities.
One popular piece might be 'The Targaryen's Bride' which delves into how fem Harry adjusts to the Targaryen court and her relationship with Rhaegar. It has a great build - up of their relationship, from initial encounters to falling in love.
A plot could involve Fem Jon Snow being trained in the ways of the dragon by Rhaegar's spirit. Since Rhaegar was known for his connection to dragons, he could guide her to discover her own dormant dragon - riding abilities. This could lead to her uniting the remaining Targaryen forces and reclaiming the Iron Throne. Or perhaps they meet in a dreamscape where Rhaegar reveals the true purpose of her existence, which is to bring peace between the North and the Targaryen - ruled South.
One great fanfiction could be 'The Targaryen Connection'. It explores an interesting relationship between female Harry and Rhaegar. The story is set in a world where the magic of Harry's world and the politics of the Targaryen realm collide. It has well - developed characters and a plot that keeps you hooked from start to finish.
There could be a fanfiction where Bella somehow travels to the world of Westeros. Rhaegar, being intrigued by this strange girl from another realm, takes her under his wing. Their relationship might develop as he teaches her about the ways of his world, and she in turn shows him a different perspective on life and love. For example, Bella's concept of a monogamous and all - consuming love could be a new idea for Rhaegar.
One interesting fanfiction might be one where Rhaegar survives the Battle of the Trident. In this story, he could return to King's Landing and try to set things right in the realm. He might face the challenges of dealing with his family's legacy and the political unrest.
There might be a fanfiction where Rhaegar time travels to meet his ancestors. In this story, he could learn from them, perhaps about dragon - riding techniques that were lost over time, and then use this knowledge to his advantage in his own time. This could lead to a whole new set of adventures and power plays in Westeros.
