Well, the Lord Beyond the Wall might be a figure who has been there since the dawn of time in the fanfic's version of the 'Game of Thrones' universe. Maybe he's a spirit or a long - lost hero who has turned into something more due to the magic and harshness of the far north. He could be a force that both the Night's Watch and the wildlings fear or revere, depending on how the story in the fanfic unfolds.
The Lord Beyond the Wall in 'Game of Thrones' fanfics can be interpreted in different ways. It could be a character who is a bridge between the living and the dead, controlling the undead hordes not as a simple villain but as a part of a greater, more complex plan. In some fanfics, he might have a backstory related to the First Men or the Children of the Forest, and his actions are driven by a sense of justice or revenge that is unique to the cold and unforgiving land beyond the Wall.
The role of the Lord Beyond the Wall in 'Game of Thrones' fanfic can be quite diverse. He could be a catalyst for change. For example, his actions might force the different factions in the Seven Kingdoms to unite against a common enemy. Or he could be a character that represents the unknown and uncontrollable forces of nature in the north. His presence might also lead to new alliances being formed, such as between the wildlings and some of the northern houses who realize that they need to work together to deal with this threat from beyond the Wall.
Well, he could be a character who has been reimagined. Jon Arryn in the original series was an important figure. In this fanfic, the 'Brightflame' addition might suggest some sort of connection to a more flamboyant or perhaps magically - inclined lineage. It's possible that he has abilities or a backstory that ties him to this 'Brightflame' concept, which could make him a key player in the fanfic's plot, different from his role in the original story.
Maybe they wanted to add their own creative twists and expand the story's universe to keep viewers engaged and offer something new.
Merlin could side with Jon Snow. Jon is a man of honor, much like Merlin himself. They both have a sense of duty towards protecting the realm. Merlin could use his magic to help Jon in his battles against the White Walkers, for instance, by creating magical barriers or enhancing the strength of Jon's army.
Daenerys Targaryen is often a popular character in these fanfics. Imagine her with the power of a wizard, she could use magic to control her dragons more effectively. Her already strong - willed and powerful character would be even more formidable with the addition of wizardry skills.
There could be a young, ambitious knight who has seen the injustices in the Seven Kingdoms and becomes a key figure in the uprising. Another might be an old and wise maester who secretly supports the uprising and uses his knowledge to help the rebels. Also, a strong - willed noblewoman who has her own reasons for wanting change could be one of the main characters.
In many 'Game of Thrones' fanfics, the Lady of Winterfell could refer to Sansa Stark. She had a complex journey in the series and in fanfics might be depicted as a strong leader ruling over Winterfell. She learned the hard ways of politics and survival, which would make her an interesting focus in fan - created stories.
There's no way to know exactly without reading it. However, in a 'Game of Thrones' - themed fanfic with 'no mercy' in the title, it's likely to have some of the fan - favorite characters in key roles. Maybe Arya Stark, with her assassin skills, could be a main character, showing no mercy to those on her kill list. Or it could be Cersei Lannister, being even more merciless in her quest for power and revenge than she was in the original series.
I really like the fanfic 'A Song of Rings'. In this story, the One Ring somehow finds its way to Westeros. The author does an amazing job of integrating the different lore. For example, how the power of the ring affects the power - hungry characters in 'Game of Thrones' is fascinating. It also shows how the characters from Middle - earth would react to the more brutal world of Westeros.
The 'forbidden love' trope can be really engaging. Imagine a love story between a character from 'Game of Thrones' and one from 'Lord of the Rings' in a crossover fanfiction. This trope can create a lot of conflict and emotional depth. And the 'rag - to - riches' or 'rise to power' trope is also seen a lot, as it shows the character's growth and transformation.
