One interesting plotline could be the White Wolf's adventures in uncharted territories beyond the Wall. Maybe he discovers a hidden civilization or a powerful magic that was previously unknown.
The lion (Lannisters) and the wolf (Starks) are significant in Game of Thrones fanfiction as they are two of the most powerful houses. Their emblems, the lion and the wolf, represent their distinct natures. The Lannisters' lion shows their dominance and aggression, while the Starks' wolf represents loyalty and wildness. In fanfiction, these symbols are often used to enhance the drama and conflict between the two houses.
One possible fanfiction could be about a group of survivors who are captured by the White Walkers. They might be used as some sort of bait to draw out other humans. For example, the White Walkers could leave a trail of the captured ones, leading the Night's Watch or other northern forces into a trap.
Well, the White Walkers story in Game of Thrones had so much potential. However, it did seem like the show threw it away. They had been a looming danger for seasons, and fans were expecting a more epic and drawn - out battle and resolution. Instead, it ended quite quickly. There were also some plot holes in how they were defeated, like Arya's sudden ability to take out the Night King. It made the whole build - up of the White Walkers' threat feel a bit wasted.
In Game of Thrones fanfiction, the relationship between the lion (Lannisters) and the wolf (Starks) is often complex. They are mostly rivals. The Lannisters are known for their cunning and power - hunger. The Starks, on the other hand, are more about honor and family. Their values clash which leads to many conflicts in the fanfiction as well as in the original series.
One reason could be time constraints. As the show went on, they had a lot of plotlines to tie up and not enough time to fully explore the White Walker story. So they just rushed through it.
Perhaps a plotline where the wild wolf has some sort of special power that it discovers and uses to influence the power struggle in the Seven Kingdoms. It could be a power related to its connection with nature, which is different from the normal magic in the 'Game of Thrones' world. This would lead to other characters either trying to use the wolf for their own gain or trying to destroy it out of fear.
