Adventure could also be a theme. Given that they are from the 'planes' world, they might embark on exciting journeys. For example, they could be on a quest to save their world from some threat or discover new lands and territories. There could also be themes of self - discovery. As they go through different experiences, they learn more about themselves and their capabilities.
I'm not sure of specific 'planes dusty and ishani fanfiction' stories offhand. But you could try searching on fanfiction platforms like Archive of Our Own. They usually have a wide variety of fan - created stories for different fandoms.
A common theme could be friendship. Given their characters, many fanfics might explore how they bond and support each other.
I'm not sure specifically as I haven't read it. But generally, a fanfiction about 'Big Valley' by someone named Dusty would likely be a fictional story created by a fan. It could be about the characters from 'Big Valley' in new adventures, relationships, or situations that the original show might not have covered.
There's also a fanfiction called 'Dusty's Discovery'. In this story, Dusty stumbles upon a secret that Dipper has been hiding. As they work through the implications of this discovery, their relationship takes an interesting turn. It delves deep into their personalities and how they interact with each other in different situations.
Dusty love novels often have a sense of nostalgia. They may be set in the past, like the Victorian era or earlier. The love in them is often more chaste and builds slowly over time. For example, in 'Jane Eyre', the relationship between Jane and Mr. Rochester develops gradually as they get to know each other's true natures.
Another theme is the power of friendship. Their initial friendship is a strong foundation, and many fanfictions build on this, showing how their friendship evolves into a deeper, more passionate love, and how that friendship helps them face the challenges that come their way.
One common theme is the struggle between heroism and normal life. Spider - Son often has to balance being a hero and dealing with school, family, etc. For example, in many fanfictions, he misses important family events because he's out fighting crime.
Another theme is redemption. Edgeworth has a past that he sometimes feels he needs to atone for, and in fanfiction, Wright is often there to help him through that. It's like in 'The Path to Forgiveness' where Wright helps Edgeworth come to terms with his past mistakes.
Transformation is a big theme. How the character changes physically and emotionally when they turn into a werewolf is often explored. Also, the concept of the moon is very common. Since werewolves are often associated with the moon, many fanfictions use the moon as a symbol for power, change, or even as a trigger for the werewolf's transformation. There's also the theme of the werewolf's inner struggle, like trying to control their animal instincts in a human world.
One common theme is love against all odds. Often, the two characters face many obstacles in their relationship, but their love prevails.
