Another option could be 'Wisdom Guides Our Blades'. This motto combines the idea of martial strength (the blades) with wisdom. It suggests that the house doesn't just rely on brute force but also on intelligence and strategy. In the complex political and military landscape of Game of Thrones, such a motto would set them apart as a house that thinks before they act.
The new house might be centered around a unique religion or belief system. Maybe they worship a long - forgotten god that gives them special powers or abilities. Their knights might perform strange rituals before going into battle, like painting their faces with symbols related to their god. They could also have a strict moral code based on their religious beliefs, which sets them apart from other houses in Westeros. For instance, they might believe in total equality between men and women in all aspects of life, which is quite different from the patriarchal norms of most Westerosi houses. This would lead to female warriors and leaders being common in their house.
One idea for a new house in a 'Game of Thrones' fanfiction could be House Frostwood. They could be from a far northern region, beyond the Wall. Their sigil could be a white wolf on a blue field, symbolizing their connection to the harsh, cold environment and the wild wolves that roam there. Their motto might be 'In Ice, We Endure'.
One impact could be on the religious beliefs of the characters. If a new god appears, existing religions might face challenges. For example, the Faith of the Seven could see a decline in followers as people turn to this new deity.
Hermione could potentially belong to House Lannister. Now, the Lannisters are known for their cunning and wealth. Hermione's intelligence could be seen as a form of cunning. She could use her magic to help the Lannisters in their financial schemes, perhaps by using magic to find hidden treasures or to create valuable items. Also, she could use her magic to protect the Lannisters from their enemies, which would be highly valued by the family.
One way is to focus on a unique location. For example, a house in a long - forgotten part of Westeros, like a hidden valley. Give it a distinct sigil, perhaps something related to the local fauna or flora there. And develop a code of honor or a particular set of values for the house members that sets them apart from the other houses in the story.
In fanfiction about House Reyne, we could see alternate storylines. For example, what if the Reyne's had managed to avoid their brutal end at the hands of the Lannisters? Maybe they could have formed an alliance with another powerful house against the Lannisters. Their sigil, the red lion, could be a symbol of their resurgence in these fictional tales.
A house gardener could fit in as a keeper of secrets. The gardens often have hidden corners and old trees that could hide things. He might stumble upon a hidden cache of weapons or a secret meeting place. His presence is often overlooked as he is just a gardener, so he can observe a lot without being suspected.
Daenerys Targaryen would likely see the new land as an opportunity to expand her rule. She would approach it with her leadership skills and her dragons. However, she would also have to be careful as the new land may have its own powerful forces. She might start by trying to make alliances with the local tribes or kingdoms, much like she did in Essos, but she would soon realize that the new land has its own unique challenges that require a different approach.
Another plotline might involve a Reyne character getting involved in the political intrigue at King's Landing. They could use their knowledge of the Lannisters' past deeds against House Reyne to manipulate the situation and gain power for themselves and their house.
One great 'Game of Thrones House Arryn fanfiction' is 'The Arryn Ascent'. It focuses on the rebuilding of House Arryn's power. The author beautifully describes the Vale's landscapes and the political maneuverings within the house.
