One possible storyline could be Jon Snow learning the ways of leadership from Stannis. Stannis, being a strict and experienced leader, could teach Jon about military strategies and the importance of justice. Jon, in turn, might influence Stannis with his more empathetic and inclusive approach, leading to a change in Stannis' view towards the Free Folk.
In the fan fiction, it might explore how Jon Snow's identity as a Stark and his connection to the North play out while he is squiring for Stannis. Stannis may initially be skeptical of Jon due to his bastard status, but as Jon shows his loyalty and capabilities, Stannis could start to see him as an asset. This could also involve Jon having to make difficult choices between his loyalty to Stannis and his love for the North.
In this fan fiction, their relationship may develop in a complex way. Stannis may initially use Jon as a tool to gain more support in the North, seeing his Stark name as an advantage. But as Jon shows his true self and his unique skills, Stannis starts to value him for who he is. Jon, on the other hand, may be initially hesitant about serving Stannis but gradually realizes that he can learn a great deal from him. Their relationship could be full of power struggles, but also moments of mutual admiration and growth.
One possible plotline could be them uniting against a common enemy. Maybe they join forces to fight the White Walkers. Another could be a political alliance where they use their combined influence to take the Iron Throne.
Yes, there are some. You can start by looking on popular fanfiction websites like Archive of Our Own. Just search for 'female Jon Snow x Stannis' in the search bar, and you'll likely find a variety of stories with different takes on this pairing.
One possible storyline is that Jon Snow uses the ice dragon to fight against the White Walkers. The ice dragon's cold breath could be a powerful weapon against the undead army. Another storyline could be that the ice dragon helps Jon Snow claim the Iron Throne. Its presence would make him a very intimidating and powerful claimant.
The idea of destiny is a big one. Writers like to play with the concept of whether Jon is truly meant to be a hero or a king. His journey to fulfill what might be his pre - ordained fate is a theme that recurs often in Jon Snow fan fiction. It gives a sense of grandeur and purpose to his character.
Another possible storyline is that Dany and Jon have to deal with the political aftermath of their relationship. There could be opposition from different houses who don't want a Targaryen - Stark union. They would then have to navigate through the complex web of politics, with Dany using her dragons as a show of force when necessary, and Jon using his diplomatic skills learned from the North. This would be a story full of intrigue, power plays, and of course, their undying love for each other.
One common theme is the union of the North and the South. Jon represents the North and Daenerys the South in a way. Their coming together is seen as a way to unite the different regions of Westeros against common threats.
It could be an epic battle. Maybe they have a misunderstanding or are forced into a fight by external circumstances.
One that stands out is 'Jon Snow's Redemption'. It's set after the events of the show and imagines a path of redemption for Jon. It shows his struggle with his identity and his attempts to make amends for past actions. It's quite a thought - provoking read.
One interesting storyline could be them uniting the kingdoms in a different way than in the original series. Maybe they find a way to combine their different leadership styles and bring about a more peaceful and prosperous Westeros. For example, Dany's experience with ruling different cities and Jon's knowledge of the North could create a unique form of governance.
