Boromir might develop a sense of wonder. Earth has so many different cultures, landscapes, and technologies. This exposure could make him less rigid in his thinking. He could start to question the way things were in Middle - earth and consider new ways of living. He might see how different races interact here in a more peaceful way compared to the tensions in his own world and strive to bring that back to Middle - earth if he ever returns.
One common theme is redemption. Since Boromir's character in the original story had some flaws and made mistakes, in these fanfics where he lives, he often gets the chance to redeem himself. For example, he might make amends for his actions regarding the One Ring.
I'm not sure if there is such a specific fanfic. Fanfics cover a wide range of themes and scenarios, but this particular one seems rather unorthodox. It might exist in some corner of the vast fanfic universe, but it's not a common or widely known concept.
One common theme is the clash of cultures. Boromir is from Gondor and Catelyn is from the North in Westeros. Their different upbringings and values often lead to interesting interactions and conflicts in fan fictions.
A good 'boromir x reader fanfic' should have a strong understanding of Boromir's character. His noble yet flawed nature needs to be accurately portrayed. For example, his pride and his loyalty to Gondor are important aspects.
One popular Boromir OC fanfiction might be those that explore an alternate universe where Boromir survives. In such stories, the OC could be a character who helps him on his new journey, perhaps a healer from a far - off land. They could develop a deep friendship or even a romantic relationship as they face new challenges together.
One common theme is the clash of different cultures. Since Boromir is from Middle - earth and the 'Harry Potter' series has its own unique magical world, there's often exploration of how their different values and ways of life interact. Another theme could be the idea of heroism. Both Boromir and the characters in 'Harry Potter' are often seen as heroes in their own right, and fanfictions might compare or combine their heroic journeys.
A common theme could be the clash of different worlds. Boromir is from Middle - earth with its medieval - like setting and magic, while Caitlyn is from a more modern - ish, steampunk - inspired world. So, stories might explore how they adapt to each other's worlds. Another theme could be their combined skills in combat or problem - solving.
One great 'boromir x reader fanfic' is 'The Unseen Bond'. It beautifully captures the essence of Boromir's character and his relationship with the reader. The story is filled with adventure and emotional depth.
