One popular theme could be friendship challenges. Since Celestia and Twilight have a mentor - mentee relationship in the original context, fanfictions might explore how their relationship is tested and strengthened in different scenarios. For example, a situation where they have a disagreement over magic use or how to deal with a new threat in Equestria.
One place to look could be on fanfiction - dedicated websites like Fimfiction. There are often a large number of My Little Pony - related fanfictions, including ones about Celestia and Twilight. You can use the search function to specifically look for stories with both of them in it and then browse through the results to find ones that seem interesting.
I'm not sure specifically which ones are the 'good' ones as lemon fanfics often involve inappropriate content. It's better to focus on non - lemon fanfics. For example, there are many fanfics that explore their friendship or adventures in a more positive and family - friendly way.
Probably not very popular in the general sense. Since it involves such a dark and against - the - norm concept for the My Little Pony franchise which is mostly known for its positive and friendly themes. But there may be a small niche of fans who are interested in exploring these more extreme and dark takes on the story.
A common theme is mentorship. Celestia often serves as a mentor to Twilight, guiding her in magic and leadership. Another theme is friendship. They develop a deep bond through various adventures.
A 'yandere' character in a fanfic is often possessive and extreme in their love or obsession. In a 'yandere Celestia and Twilight fanfic', Celestia being a yandere could mean she has an over - the - top, perhaps even dangerous, love for Twilight. This could lead to complex power dynamics as Celestia is often in a position of authority. Twilight, on the other hand, might be the object of Celestia's affections, and have to deal with the consequences of such intense feelings. It could also explore themes like loyalty, friendship, and how far one would go for love in the context of the My Little Pony universe.
Clop - related fanfiction is not something that should be promoted as it goes against the family - friendly nature of the My Little Pony franchise. Instead, consider exploring fanfictions that focus on their adventures, like them teaming up to solve a magical mystery in Equestria. You can search for such stories on various fan - created platforms and forums.
Another place to look is Archive of Our Own (AO3). It has a wide range of fan - created content, including many My Little Pony fanfictions. Just use the search function and type in 'Celestia Adopts Twilight' and you should get some relevant results. However, make sure to follow the website's rules and guidelines while browsing.
Well, it could be part of a really edgy or non - traditional fanfiction. It might be that the author is trying to create a shock factor. Sometimes in fanfiction, people like to break the norms of the original story, and this could be one such extreme example where Twilight Sparkle, who is usually a good - natured character, is made to be a killer of Celestia, perhaps due to some kind of power struggle or misinformation in the story they've created.
Well, there's a fanfiction called 'Celestia's Guidance for Twilight'. In this one, Celestia takes Twilight under her wing in a more in - depth way than in the original story. It shows their relationship evolving in a very interesting manner. There's also 'Twilight and Celestia: The Enchanted Quest' which is about them going on a quest together to save their magical world from a mysterious threat.
