There might be a character who is a bit of an outcast but has special abilities that become crucial in the story. They could be initially underestimated by others in the 'beyond duty' setting but end up being a key player.
One idea could be exploring uncharted territories in the 'beyond duty' world. Maybe the characters face new and strange creatures that test their limits.
The conflict. The struggle between duty and desire is a very relatable concept. In the Twilight world, it adds an extra layer of depth to the characters. For example, a vampire might have a duty to their coven but a desire for a human. It creates interesting storylines.
There is a fanfic named 'Duty's Call and Desire's Temptation'. In this story, it shows how the characters' sense of duty is constantly at odds with their desires. It's a great read as it keeps you on the edge of your seat, wondering whether they will choose their duty or give in to their desires. It also has some great character development.
One common theme is the exploration of different relationships. For example, fanfictions often re - examine the relationships between vampires and werewolves. Another theme is the expansion of the supernatural world, like introducing new types of magic or creatures.
One interesting aspect could be the unique take on the Twilight universe with a focus on royal duties. It might explore how the characters, like the vampires or werewolves, interact within a more formal, royal setting. For example, how their natural abilities play into their royal roles, whether it's for protection or governance.
Often in such fanfictions, we might see the main characters from Twilight like Jacob being reimagined in the 'beyond time' context. He could be a guardian of a time portal in the twilight realm. And then there could be a mysterious character, say Sophia, who enters the story from outside the normal Twilight universe. She has knowledge of both time and twilight magic and she guides the other characters through their adventures in this strange 'beyond time twilight' world.
I'm not sure specifically what 'a lion duty fanfic' is about as there could be many interpretations. It might be a fan - created story related to lions and some kind of duty they have in a fictional world, perhaps in a game, movie or book setting.
In Call of Duty Frost fanfics, the setting can be expanded too. Instead of just the usual war - torn landscapes, authors might take Frost to different parts of the world or even other planets in some really out - there fanfics. His skills can be enhanced or modified in these stories as well. It all depends on the creativity of the writer. Some fanfics may also explore Frost's family life, if he has any, which adds a whole new layer of depth to his character.
One common theme is the power of love to transcend the boundaries of life and death. In Twilight, the vampires are already sort of 'between' life and death, and when you add the concept of love beyond death, it becomes even more complex. Another theme could be sacrifice. A character might sacrifice their own 'undeath' or some other important aspect to be with their loved one who has passed on.
