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.
One common theme is mentorship. Celestia is often Twilight's mentor, so the fanfics explore how Celestia imparts knowledge and wisdom to Twilight. Another theme is friendship.

Twilight sleep could be a plot device in fanfic. It might be used to show a character's vulnerability or to set up a situation where they are in a different state of consciousness.
