In a 'Game of Thrones Epilogue Fanfiction', it could be about the adventures of the next generation. The children of the main characters might discover new threats or mysteries. For instance, they could find hidden secrets about the White Walkers that were not fully explored in the original series, leading to a new quest.
Another plot might focus on the relationships between different regions. With the war over, trade and cultural exchanges could be explored. The Iron Islands might finally fully integrate with the mainland, and Dorne could share its unique culture more widely. This could lead to a more unified but diverse Westeros.
The children of the original characters would be likely main characters. For example, Jon Snow's (if he has any) descendants. They could inherit his sense of honor and face new challenges in the post - war Westeros.
One possible plot could be Ron getting lost in the Seven Kingdoms. He'd have to use his wits and some of his basic magic skills to survive. Maybe he'd get involved with a group of rebels against a tyrannical king, using his knowledge of fighting dark forces from the wizarding world to help them.
One possible plot could be that Naruto characters are transported to the Game of Thrones world. Naruto, with his strong will and ninja skills, might get involved in the power struggles. He could form an alliance with some of the noble houses, perhaps using his Rasengan as a display of power to gain respect. The 'lemon' aspect could be a romantic sub - plot between Naruto and a GoT character, like Arya. They might have a secret relationship that adds an interesting dynamic to the overall story.
One possible plot could be that Draco Malfoy is magically sent to Westeros. He gets caught up in the power struggle between the Starks and the Lannisters. Maybe he tries to use his knowledge of magic to gain an advantage, but soon realizes that the politics of Westeros are far more complex than he expected.
One possible plot could be that a giantess emerges from the far North, beyond the Wall. She could be a remnant of an ancient race. The characters in the Game of Thrones world might initially see her as a threat. For example, the Night's Watch could fear she is allied with the White Walkers. But as the story unfolds, it turns out she has her own motives. Maybe she is seeking a lost relic that was stolen from her kind long ago. And she might form an unexpected alliance with a group of outcasts in Westeros to achieve her goal.
A plot could revolve around a dragon in Game of Thrones having similar characteristics to the dragons in Dark Souls. Maybe the Night King has some connection to the Abyss from Dark Souls. A character from Dark Souls could team up with Jon Snow to fight against the White Walkers. The Dark Souls character could introduce new ways of forging weapons and armor that are far more advanced than what is known in Westeros, giving the good guys an edge in the fight.
Perhaps Daenerys comes to Winterfell seeking refuge from the approaching White Walkers. The people of Winterfell are initially hesitant to welcome her, but as they see her determination to fight the common enemy, they start to accept her. Daenerys then discovers some ancient secrets in Winterfell's crypts that could potentially help in the battle against the undead. Her dragons also start to interact with the magical elements in the North in strange and unexpected ways.
One possibility is that it delves deeper into the mysteries that were left unsolved in the movie. It could explore the origin of some of the powerful cards or the true nature of the dark forces that were hinted at. The fanfiction might also introduce new characters who are related to the existing ones, like a long - lost relative of Kaiba who has some secrets about the Millennium Items.
A possible plot could be that a powerful sorceress in the Game of Thrones universe discovers a long - lost spell. This spell, when cast on a character, causes a slow and unexpected breast expansion. It could be used as a form of transformation to either gain power or as a curse. For example, if it was cast on a female character in a noble house, she might initially be shunned but then learn to use this new 'gift' to her advantage in the political games of the Seven Kingdoms, perhaps using it to charm potential allies or intimidate enemies.
One possible plotline could be the characters in the afterlife having to atone for their sins. For example, characters like Joffrey might face some sort of punishment or redemption arc in the afterlife realm. Another could be the great heroes of Westeros coming together to fight against some new threat that exists even in the afterlife. Maybe they have to stop a dark force from spreading chaos among the souls. And perhaps the Starks and Lannisters could put aside their differences and work towards a common good in this afterlife scenario.
