In many Dance of Dragons fanfictions, Jon Snow often emerges as a key figure. He might bring his unique leadership skills and moral compass. For example, he could use his experience with the Night's Watch to unite different factions in the Dance of Dragons' chaotic setting. His connection to the North could also play a role, perhaps rallying northern support against the dragon - ridden Targaryens or other power - hungry groups.
In some fanfictions, Jon Snow could gain control over a dragon. Given his special connection to the supernatural, it's not entirely far - fetched. This would make him an extremely powerful player in the Dance of Dragons, able to tip the balance of power in any direction he chooses.
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.
You could try searching on popular fanfic websites such as Archive of Our Own (AO3). It has a vast collection of fan - created stories, and there's a good chance you might find the 'Jon Snow has 3 girls dragons fanfic' there.
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.
One idea could be a story where Robert Baratheon discovers Jon Snow's true parentage earlier. This could lead to a complex relationship where he sees Jon as a potential heir or a powerful ally. He might take Jon under his wing, train him in the ways of leadership and warfare, much like he did with Ned Stark's other children.
