In a fanfiction about Princess Luna's sick day, it could start with Luna waking up feeling unwell. She tries to hide it at first because she doesn't want to worry the other ponies. But as the day goes on, her condition worsens. The ponies then notice her strange behavior and find out she's sick. They all come together to create a comfortable and healing environment for her. They might bring her warm blankets, her favorite foods like moon - berries, and tell her stories to keep her spirits up.
Well, it combines the unique character of Princess Luna from My Little Pony with the 'lemon' genre. Usually, it might explore different aspects of her character in a more adult - oriented or romantic light that is not typically shown in the original series. This can make it stand out as it gives a different perspective on the character.
One popular theme is Luna's redemption. Since she had a dark past in the show, many fanfictions explore how she fully overcomes her inner demons and becomes a more beloved princess. Another theme is her relationship with other ponies, like Twilight Sparkle or Celestia.
Princess Celestia can raise the sun, has strong magic for ruling and protecting Equestria. Princess Luna can raise the moon and also has magic related to the night, like controlling the stars.
Princess Celestia is the ruler of Equestria, responsible for raising the sun. Princess Luna was once envious and turned into Nightmare Moon. Celestia had to banish her to the moon. But later, Luna was redeemed. They both play important roles in maintaining the balance of day and night in Equestria.
Fluttershy would also be great. She has a gentle nature and is good at taking care of others. She could bring Luna some herbal remedies she's collected from the forest and stay by her side to keep her calm.
