Perhaps a young knight who is given a lordship as a reward for his heroism in a great battle. He is inexperienced in ruling but has a strong sense of justice. He has to learn quickly how to manage his lands, deal with political intrigue, and protect his people from bandits and rival lords. He is also a bit of a romantic, and his love interest could be a lady from a neighboring house, which adds another layer of drama to his story.
One idea could be a new lord who is a long - lost heir to a powerful but fallen house. He starts from nothing, gathering a small group of loyal followers, some outcasts and misfits. He uses his wits and new - found knowledge of forgotten battle tactics to slowly rise in power. He might form an alliance with a group of local peasants who are tired of being oppressed by the existing lords. Through their combined efforts, they start to build a new, more just community which catches the attention of the greater powers in Westeros.
Maybe it's a former soldier who has shown great courage during a battle. He could have been the one to hold the line at Moat Cailin during a crucial fight, and in recognition of his valor, he's made the new lord. His military experience would be a great asset in ruling the area.
The new lord of Moat Cailin in fanfiction could be a great hero. He might use his position to improve the lives of the people there. He could start by strengthening the defenses of Moat Cailin, making it a more formidable stronghold. He may also establish trade routes, bringing prosperity to the area. This could attract more people to come and live in Moat Cailin, increasing its power and influence in the North. And he could form alliances with other noble houses, not just for military purposes but also for cultural and economic exchanges.
One great 'Lord of the Rings and Game of Thrones Fanfiction' is 'The Convergence of Westeros and Middle - earth'. It combines the magic systems of both in an interesting way, like how the One Ring could interact with the magic in Westeros.
I really like the fanfic 'A Song of Rings'. In this story, the One Ring somehow finds its way to Westeros. The author does an amazing job of integrating the different lore. For example, how the power of the ring affects the power - hungry characters in 'Game of Thrones' is fascinating. It also shows how the characters from Middle - earth would react to the more brutal world of Westeros.
The 'forbidden love' trope can be really engaging. Imagine a love story between a character from 'Game of Thrones' and one from 'Lord of the Rings' in a crossover fanfiction. This trope can create a lot of conflict and emotional depth. And the 'rag - to - riches' or 'rise to power' trope is also seen a lot, as it shows the character's growth and transformation.
A very popular Jon Snow fanfiction is 'Jon Snow: The True Heir'. It plays on the idea of his true parentage and how that could change the power dynamics in the Game of Thrones realm. In this fanfic, he has to fight for his rightful place. Another one is 'Jon Snow's Unseen Path' which shows his journey through some less - explored aspects of the story. 'Jon Snow and the Alliance' is also quite good, where he forms unexpected alliances to survive the cutthroat Game of Thrones politics.
The biggest challenge is probably the different magic systems. In 'Lord of the Rings', magic is more ethereal and associated with certain races. In 'Game of Thrones', it's more of a mysterious and often dark force. Combining these two concepts without making it seem forced can be difficult.
Power struggle is a very common theme. Just like in the original series, the OC lords in these fanfictions often strive for more power, whether it's over a particular region or in the whole of Westeros.
