A plot could center around a mystery that only Princess Luna and King Sombra can solve together. There is an ancient magic at play that is causing chaos in Equestria. Luna's connection to the night and Sombra's dark magic knowledge are both needed to decipher the mystery. Along the way, they face challenges that test their abilities and also their new - found trust in each other.
Well, one possible plot could be that they start as enemies as in the original lore. But then, an external threat forces them to work together. They gradually learn about each other's pasts and find some common ground. Maybe they both had difficult upbringings in different ways. And in the end, they form an unlikely alliance that changes the power dynamics in Equestria.
In terms of the plot, it could start with Sombra's return or some sort of threat that he poses. Luna then steps in to deal with it. The setting within the My Little Pony world would be important. It could be set in Canterlot or some other location. The fanfic might also introduce new characters or use existing ones to support the main plotline between Luna and Sombra.
Their relationship could develop in a more complex way. Maybe Sombra has a hidden past that Luna discovers, which makes her pity him. This could lead to her trying to help him reform. Sombra, on the other hand, might be initially distrustful but then gradually open up to Luna as she shows him kindness. They could end up as friends or at least allies who have a deep understanding of each other.
One common theme could be the battle between light and dark. Luna represents the moon and has an association with the night, which can be seen as a time of mystery and sometimes danger. King Sombra is a dark character. So the fanfic may explore this contrast in terms of their powers and personalities.
One possible story could be that Princess Luna, with her connection to the night, tries to understand the darkness within King Sombra. Maybe she believes there is some good left in him despite his evil deeds. She could use her lunar magic to reach into the shadows that surround him and try to communicate with his true self.
The plot could revolve around a competition. Prince Artemis challenges Princess Luna to a series of tests to prove which one is more powerful in controlling the night - related magic. As they go through the challenges, they start to respect each other more. In the end, instead of a clear winner, they realize that by working together, they can achieve even greater things with their magic.
Perhaps in the fan fiction, King Sombra has a secret past that is linked to Princess Luna. He was once a pony like any other, but a dark magic experiment gone wrong turned him into the monster he is now. Luna discovers this truth and feels a sense of responsibility for him. She tries to reverse the magic that corrupted him. This involves going on a journey to find the origin of the dark magic, facing many dangerous creatures and challenges along the way. And all the while, Sombra is fighting his own inner demons, not sure if he wants to be saved or if he should continue his path of destruction.
One idea could be a story where Luna and Sombra meet in a dream realm. Luna, being the princess of the night, has the power to traverse dreams. Sombra, once a powerful and dark figure, could be lost in this dream realm. Luna tries to understand his past and help him find redemption. It could explore themes of forgiveness and the power of understanding.
Perhaps in the fanfic, Luna has a nightmare about her past as Nightmare Moon. She wakes up crying because she fears that she could lose control again and turn back into that evil form. This would show her internal struggle with her own identity and the fear of repeating her past mistakes.
Power and corruption is another common theme. King Sombra was power - hungry in the original story, and fanfics expand on this. They might show how his thirst for power not only affects himself but also those around him. It can also explore how power can corrupt even the best of intentions.
No. King Sombra is a baddie and Luna is a princess. Their relationship is more about opposition in the story, not love.
