There are some out there. In these fanfics, Jon Snow's journey to becoming the king of dragons can be really exciting. He might face challenges from other claimants to the throne or from those who fear his new - found power with the dragons. It's a really cool concept that allows for a lot of creative storytelling.
In such a fanfic, first of all, Jon Snow's Targaryen lineage plays a big role. It's what often gives him the connection to the dragons. Then, there's the part about taming the dragons. Each dragon has its own personality, and Jon has to figure out how to work with them. And of course, the political aspect. With the dragons on his side, Jon has to deal with other lords, kingdoms, and potential rivals. He might have to use the dragons' power to enforce his rule or fight off invaders. This all makes for an exciting and complex story.
Jon Snow could potentially have allies like the Mormonts. They have always been loyal to the Starks. Maybe even some of the Dornish houses might side with him. They have their own reasons to oppose the current power structure in Westeros. And of course, his friends from the Night's Watch who left with him or believe in his cause could be his allies in this conquest. He might also gain the support of some of the maesters who see the value in his leadership for the future of Westeros.
The wildlings might be his allies. After all, Jon Snow has had interactions with them before. They are fierce fighters and could fight alongside him against a common enemy.
In this fanfiction, one of the key battles Jon Snow might participate in could be the Battle of the Whispering Wood. His skills as a fighter would be put to good use there, sneaking around and taking out enemies. Another could be a fictional battle near the Wall, where he defends against some new threat that has emerged during Robb's war.
He might go back to Winterfell and claim his rightful place as a Stark. This would change the whole power dynamic in the North and also his relationship with his siblings.
His reign would likely be one of justice and fairness. Jon has always been a character who values honor and doing what's right for the people. He would probably focus on rebuilding the Seven Kingdoms after all the destruction from the wars. He'd try to unite the different regions, regardless of their past grudges.
In this fanfiction, Jon Snow's character could develop in several ways. Firstly, his relationships with other characters might change. He may form stronger bonds with his fellow soldiers, learning to trust them more. Secondly, his understanding of politics and power could grow. As he is involved in Robb's war, he witnesses the political maneuverings that go on behind the scenes. This could make him more cynical or more determined to fight for justice, depending on how he interprets these events. Moreover, his combat skills are likely to improve, and this newfound strength could give him a different perspective on his own capabilities and his place in the world.
It's possible that he has a different vision for his life. He might have seen a different future for himself, one where he doesn't have to be bound by the rules and isolation of the Night's Watch. He may want to be more involved in the politics and power struggles of the Seven Kingdoms, rather than being on the Wall.
