Another theme might be self - discovery. The characters' darkest desires could lead them to discover new aspects of themselves. For instance, a werewolf might find out through his darkest desire that he has a stronger connection to the spiritual side of his nature than he thought. And the primal instinct could be a driving force in this self - discovery journey, as they learn to accept or control these instincts.
Love in the face of primal instincts and darkest desires could also be a theme. In the 'Twilight' world, love often has to overcome the differences between species and their inherent instincts. In this fanfic, the characters' darkest desires might test their love in new ways. For example, if a character's darkest desire is power, it could put their relationship at risk as they might be tempted to sacrifice love for the pursuit of that power.
I haven't read this specific fanfic, but generally, a 'Twilight' fanfic might explore different aspects of the original 'Twilight' world. It could delve deeper into the primal instincts of the characters, like vampires' hunting instincts or werewolves' territorial instincts. And the 'darkest desire' part might involve some hidden, perhaps more morally ambiguous wishes of the characters.
It's likely that the main characters would include some of the original Twilight characters like Edward Cullen. Since it's a fanfic about 'darkest desire', Edward's struggle with his own vampiric desires might be explored more deeply. Maybe his desire to fully embrace his vampire nature while also being in love with Bella could be a central aspect.
One interesting plot could be a new vampire character with a 'darkest desire' that challenges the existing power dynamics in the Twilight universe. For example, a vampire who desires to expose the vampire world to humans for some self - serving reason.
Survival is a very likely theme. The Darkest Dungeon is a harsh place, and the Crusader and Vestal must do whatever it takes to survive. This could include making difficult decisions, facing their fears, and using their unique skills to stay alive. Additionally, the theme of sacrifice might be present. The Crusader, being the more combat - oriented, might be willing to sacrifice himself to protect the Vestal, and the Vestal might sacrifice her own well - being to keep the Crusader alive through her healing, showing the depth of their relationship and commitment to each other in the face of danger.
Well, it's the exploration of new concepts. For example, the idea of instincts in the Twilight universe can lead to different power dynamics, relationships, and storylines. It allows fans to see a different side of the familiar world. It might explore how an instinct for survival changes the way a character approaches a situation, or how an instinctual attraction can create new romances. There are so many possibilities that make these fanfics really engaging.
Love could also be a theme, although it might be a bit more complex given the different natures of their respective stories. Maybe it's not a romantic love at first, but a love for each other's strength and the way they face challenges. The fanfic could explore how they come to respect and care for each other in a way that goes beyond just a simple acquaintance, and perhaps over time, that could develop into a deeper form of love that is unique to their combined story.
One possible theme could be freedom. Just as the Emancipation Proclamation was about freedom in the real - world context, it could be translated into the Twilight universe as a character's journey towards freedom from certain constraints, like a vampire breaking free from an old - fashioned coven's rules.
One possible theme could be sacrifice. Maybe Twilight Sparkle sacrifices herself to save her friends or Equestria. Another theme might be dealing with grief among the other ponies after her death.
One possible theme could be redemption. A character who has made mistakes in the Twilight world might be seeking redemption and this is how they break their silence. For example, a vampire who has been living in the shadows of their past actions.
One possible theme could be the exploration of Bella's character in a different light. Instead of the innocent and somewhat shy Bella from the original, she might be shown as more confident and in - control in this stripper role. Another theme could be the contrast between her new life as a stripper and her old life in Forks. There could also be themes related to society's perception of strippers and how Bella deals with that while still being part of the Twilight world.
