Jon Snow would be a great choice as he has strong ties to the North already. His story of being a bastard and rising to leadership could be further explored in a North - centered fanfiction.
Arya Stark could also be a main character. She has the skills of a warrior and her time in Braavos could give her unique insights to bring back to the North. She could use her Faceless Men training to fight against threats to the North, like the remaining traitors or new invaders.
A new character could be the main character too. For example, a young girl from a small fishing village in the North. She discovers she has a special ability, like being able to communicate with the direwolves, and uses this ability to unite the different clans of the North against a common enemy.
It could be a young apprentice wizard who has just discovered his powers. He is eager to prove himself and protect the North from all the threats it faces.
Most likely the Starks would be main characters. Jon Snow, as he has strong ties to the North and is a natural leader. Sansa Stark too, with her new - found political acumen. Arya could also be important as she has her own brand of justice she might bring to the North's cause.
In some fanfictions, the powerful North could be about the Stark family members unlocking their latent abilities. Maybe Arya Stark returns to the North and uses her skills as a Faceless Man not just for personal revenge but for the good of the North. Bran could use his greenseeing abilities to foresee threats and guide the North's strategies. Sansa, with her political acumen, could help in forging international relations that strengthen the North's position. All these together could make the North a very powerful entity in the Game of Thrones fanfiction world.
In fanfiction, the North could become a superpower if it were to harness the power of the Wall. Maybe there are secrets within the Wall that can be used for defense or offense. The Night's Watch, which guards the Wall, could be reformed into a more powerful military force in these stories. The North also has a rich cultural heritage that could be explored in fanfiction to give it an edge, like their unique forms of art that could be turned into a form of psychological warfare against other regions.
In some more creative fanfictions, an outsider, like a mysterious traveler from the Free Cities, could be her love interest. He could bring new ideas and perspectives to the North, and their relationship could be a way to bridge the gap between the North and the rest of the world.
In Game of Thrones fanfiction, the 'Strong North' often represents a concept of a powerful and independent northern region. Writers may explore how the North, with its unique culture and strong people, resists outside threats. For example, they might depict the North's military strength, like its large number of well - trained soldiers and its ability to withstand sieges. This could also involve the loyalty of the northern houses to each other and to their leaders.
One possible fanfiction could be about a young lord in the North who unites the various houses against a new threat from beyond the Wall. He uses his wits and the strength of the North's people, along with their loyalty to their land, to form an army that is not only strong in numbers but also in spirit.
One idea could be a story about a young mage in the North who discovers an ancient magic that can control the weather. This magic was long forgotten but is now resurfacing. The mage has to learn how to control it while also dealing with the political unrest in the North.
The North in Game of Thrones has always been a place full of mystery, especially when it comes to magic. In fanfiction, you could explore the idea of the North having a connection to an elemental magic. For example, the ability to communicate with the spirits of the earth, ice, and wind. This could be used to protect the North from invaders.
In fanfiction, the North can be a superpower in 'Game of Thrones' by having unique resources. For example, its vast forests could provide an endless supply of timber for building strong fleets and fortifications. The Northmen's tough and hardy nature also gives them an edge in warfare. Their loyalty to their lords and the land makes them a united force that can withstand attacks from other regions.
