One great MLP Princess Celestia fanfic is 'The Sun's Daughter'. It delves deep into her backstory and her relationship with Luna. It shows a more vulnerable side of Celestia which is really interesting.
A common theme is sisterhood. Given their relationship as sisters, many fanfics explore the deep bond between them, including how they rely on each other and support one another in ruling Equestria.
One possibility is that their parents were powerful celestial beings. They might have ruled over a vast and magical realm long before Celestia and Luna came into power. Their parents could have been responsible for creating the very fabric of the Equestrian world, with its unique magic and diverse landscapes.
It could be another powerful magical being. Maybe a long - lost love from another dimension who has the power to traverse realms and had a brief but passionate encounter with Celestia.
One common theme is mentorship. Since Celestia is a wise and powerful figure, she often takes on the role of mentoring the reader in fanfics. Another theme is adventure. The reader usually goes on some sort of adventure with Celestia, whether it's exploring Equestria or a more magical realm. Friendship is also a big theme, as the relationship between the reader and Celestia develops into a strong friendship in many of these fanfics.
Writing fanfiction about a non - human character like Princess Celestia and a human can be a creative and interesting concept in the realm of fan creativity. However, it should be done within the boundaries of good taste and respect for the source material. If it involves inappropriate or unethical themes, then it is not appropriate.
They could have the power of creation. Just as Celestia and Luna are associated with the sun and moon, their parents might have been the ones to create these celestial bodies in the first place. This power of creation could extend to the creation of life forms, magical creatures, and even the various elements of the Equestrian world.
It could be that their parents were the ones who first discovered the magic of the sun and the moon. They taught Celestia and Luna how to control these celestial bodies. The fanfic might delve into the family's secrets, like hidden spells or ancient prophecies that only their family knew. It could also show the relationship between Celestia and Luna as sisters growing up under their parents' guidance.
The fanfic could show their parents as travelers from a far - off land. They brought with them new kinds of magic that they passed on to their daughters. Maybe there was a family feud among the alicorns, and Celestia and Luna's parents had to make difficult choices to keep their family safe. This would add drama and intrigue to the story. It could also explore how Celestia and Luna's personalities were shaped by their parents' actions and decisions.
Well, Princess Celestia is a very interesting character. She's powerful, wise, and has a long history in the MLP world. Fanfics about her allow fans to explore parts of her character that may not be fully shown in the original series, like her early years or her relationships with other characters in more depth.
