In some fanfictions, the ice dragon might have a connection to the White Walkers. It could be a powerful weapon that was once used by them but has now broken free. This would create a complex situation where different factions would try to either use it against the White Walkers or prevent it from falling back into their hands.
One interesting plotline could be the ice dragon's role in changing the power dynamics in Westeros. It might side with a particular house and help them gain an upper hand in the battles for the Iron Throne. For example, if it allies with House Stark, it could turn the tides against their enemies, freezing their forces and creating a path to victory.
One idea could be the Ice Dragon forming an unexpected alliance. Maybe it teams up with a group of outcasts in Westeros, like a band of wildlings and a disgraced knight. Together, they journey across the frozen North, facing White Walkers and uncovering ancient secrets about the dragon's origin.
Jon Snow is often associated with the ice dragon in many fanfictions. Given his connection to the North and his role in the fight against the White Walkers in the original series, it makes sense for him to be linked to such a powerful and ice - related entity like the ice dragon.
One possible plotline could be a character's accidental transformation. For instance, a young character exploring an ancient ruin stumbles upon a magical artifact or spell that causes them to transform into a dragon. This then sets them on a journey to find a way to reverse it or to use their new form for good.
One interesting plotline could be Harry using his magic skills in the world of Westeros. For example, he might use spells to defend against the White Walkers. Another could be his interactions with the different houses, like forming an alliance with House Stark through his friendship with Jon Snow.
One interesting plotline could be a different ending for some of the main characters. For example, instead of Jon Snow going to the Wall again, he could become the king of the Seven Kingdoms. Another plotline might involve Daenerys not going mad and ruling Westeros in a more benevolent way. There could also be fanfictions where Arya Stark uses her skills in a completely new adventure, perhaps exploring new lands beyond Westeros.
Another plotline might involve reincarnation as a wildling. The character then tries to unite the wildlings in a more organized way, using their knowledge of military tactics from the modern world. They could form alliances with some of the northern houses, changing the whole dynamic of the conflict between the Night's Watch and the wildlings.
One interesting plotline could be the different fates of the Stark children. For example, in some fanfictions, Sansa might use her new - found political acumen to completely reshape the North, not just as a lady but as a true leader, making alliances that were never seen in the original series. Another could be about Daenerys. Maybe in a fanfic, she lands in Westeros and instead of immediately going for the Iron Throne, she focuses on building strong relationships with the common folk first, which changes the entire power dynamic in the Seven Kingdoms.
One interesting plotline could be a Kingsguard member having to choose between loyalty to a tyrannical king and protecting the innocent. For example, if the king orders unjust executions, the Kingsguard might struggle with their oath.
One interesting plotline could be them ruling Winterfell together. Jon as the military leader and Sansa handling the political aspects. It gives a different perspective on how the North could be governed.
One interesting plotline could be a modern-day retelling where the political intrigue of Westeros plays out in a corporate setting. Characters might battle for control of a powerful company instead of the Iron Throne. For example, Jon Snow could be a young, idealistic employee trying to expose the corrupt practices of his superiors, much like the power struggles in the original series.
