In addition to the RWBY girls, there could be other characters like Ozpin. He is an important figure in the RWBY world and his knowledge and leadership could play a crucial role in a 'rwby vale or darkness fanfic'. Also, characters like Qrow might be involved as he has his own connections and abilities that could be relevant in the fight against the darkness in Vale.
The 'rwby vale or darkness fanfic' may be about the different aspects of Vale that are affected by the darkness. It could be about how the city's infrastructure, its people, and the Huntsmen and Huntresses within it respond. It might depict the RWBY team uncovering secrets about Vale that are related to the darkness, and how they use these newfound revelations to their advantage in the fight. There could be new characters introduced as well, either allies or foes in this battle between Vale and darkness.
Ruby Rose is often a common character. Given her role as the main protagonist in RWBY, it's natural for her to be involved in fanfictions set in the Vale of Darkness. Her courage and determination would be put to the test in such a dark and dangerous setting.
Since I haven't read this particular fanfic, it's hard to say for sure. But it could feature the main RWBY characters like Ruby, Weiss, Blake, and Yang. Maybe they are the ones who have to face the slithering darkness.
A plotline could also focus on the personal growth of a particular character as they navigate through the Vale of Darkness. For instance, Ruby might struggle with her own fears and insecurities in this dark and dangerous place, but through her experiences, she emerges stronger and more confident, with a deeper understanding of her role as a Huntress.
It's hard to say for sure without reading it, but it's likely to include Ruby, Weiss, Blake, and Yang as they are the main characters in RWBY and this is a RWBY - related fanfiction.
Blake could also work well as the main character. Given her past and her connection to the White Fang, she has a lot of internal conflict. The God of Darkness could either prey on that conflict or offer her a way to resolve it in a way that is both tempting and dangerous. This would make for an interesting exploration of her character.
Ruby could be one. Since she is a central character in RWBY, in fanfiction, she might be the one to face off against the God of Darkness or be somehow influenced by his presence. Another could be Salem. Given her connection to dark forces in the original RWBY story, she could have a more in - depth relationship with the God of Darkness in fanfiction.
In this fanfiction, aside from the core RWBY team, there could also be other important characters. Ozpin might play a role as he often has knowledge and guidance to offer. Qrow Branwen could also be involved as he is Ruby's uncle and has his own set of skills and connections. Additionally, characters like Pyrrha Nikos might make an appearance if the story is set in a timeline where she still exists, and she could be a powerful ally in the battle against the darkness.
The 'slithering darkness' in the 'rwby fanfic' might represent a metaphorical or literal darkness. Literally, it could be a new kind of creature with a slithering movement pattern that brings chaos and danger to the world of RWBY. Metaphorically, it could be the spreading of evil thoughts, a growing corruption within the kingdoms or among the characters. The fanfic could then be about the heroes' journey to combat this darkness, with all the action, character development, and exploration of the RWBY universe that comes with it.
There might be a character who is an expert in a particular field relevant to survival, like a former military person with combat and survival training. And there could also be a more vulnerable character, perhaps a young person or someone with a disability, who the group has to protect. This would add an extra layer of complexity to the story and the relationships between the characters.
