I'm not sure specifically as there could be many different interpretations of this fanfiction. It might be about a lone knight in the Remnant world of RWBY, perhaps on a quest or facing some great challenges.
Since I haven't read this specific fanfiction, I can't say for sure. But it could be the Remnant knight as the main character, and perhaps some other RWBY - related characters like Ruby, Weiss, Blake, or Yang might make an appearance.
Some fanfictions might focus on the relationships the Remnant Knight has within the RWBY universe. For example, how they interact with Team RWBY. They could be a mentor figure, teaching the team about ancient Remnant lore and combat techniques that are unique to the Remnant Knight's heritage.
The'mother of remnant' in RWBY fanfiction is a highly variable concept. It could be a long - ago queen who united the early tribes and laid the foundation for the kingdoms, so she is seen as the mother in a metaphorical sense. Or it could be a being from another dimension who came to Remnant and started the cycle of life and death there. Fanfic writers have a lot of creative freedom with this concept, so there are countless possibilities for who she could be.
In RWBY fanfiction, 'mother of remnant' often represents a very important and often mysterious figure. It could be a character who has a profound influence on the history or the very essence of Remnant. Maybe she was involved in the creation of the kingdoms or the origin of the Grimm. It's a concept that allows fanfic writers to explore the deep lore and untold stories of the RWBY universe.
First, do a lot of research on both the US culture and the RWBY Remnant world. Know the rules of Dust, the different kingdoms in Remnant, and how Huntsmen and Huntresses operate. Also, understand the typical US values and behaviors. Then, create an interesting plot that combines elements from both. For example, a US student exchanges into Beacon Academy and has to deal with both schoolwork and Grimm attacks.
One great 'rwby white knight fanfiction' is 'The Knight's Return'. It really delves into the relationship between Weiss and Jaune in a very interesting way. The story has a great plot that involves them facing challenges together and growing closer as a result.
In RWBY fanfiction, the 'Black Knight' could be a variety of original characters created by different authors. It might be a mysterious figure with a dark backstory, perhaps having some sort of vendetta against the main characters or being involved in a shadowy plot within the RWBY universe as envisioned by the fanfic writer.
Ruby could definitely be a main character. She has a curious nature and would be very interested in exploring the new American - influenced elements in Remnant. Weiss might also be a main character as she comes from a wealthy and influential family, and she could play a role in how the new American - like concepts are received in the upper echelons of society. Blake could be involved as well, perhaps using her knowledge and experience to analyze how these new ideas might impact the Faunus community. And of course, Yang, with her bold and fearless personality, would be right in the middle of any action or change related to the American influence in Remnant.
Another concept might be the crossover of powers. In some fanfictions, Earthlings could gain the powers of the RWBY characters, like semblances. This would lead to all kinds of new storylines, such as how they would use these powers for good or evil. It could also explore how the RWBY characters would train Earthlings to control these newfound abilities.
