A fantasy - based night blooming cereus fanfic could involve the cereus being a portal to another world. A curious adventurer stumbles upon the flower one night and, as it blooms, is sucked into a magical realm filled with strange creatures and beautiful landscapes. There, they must find a way to return home while also learning the secrets of this new world related to the night blooming cereus.
Perhaps a fanfic where a night blooming cereus is the centerpiece of a love story. A young couple meets near the cereus every night it blooms. They share their dreams and fears under the moonlight while the beautiful flower is in full bloom. But then, one of them has to move away, and they struggle to keep their relationship alive, with the cereus serving as a symbol of their love.
Another option is to set it in a secret garden within a large, old mansion. The night blooming cereus is hidden among other exotic plants. The garden has old statues and fountains, and the cereus is protected by an ancient magic that the main character discovers as they explore the garden at night.
One idea could be to explore what happens after the events of the play. For example, how the relationships between the characters develop further. Maybe Hermia and Lysander have some small arguments as they start their new life together, and they have to learn to overcome them, just like any real couple would.
Well, perhaps the Pokeballs in this fanfic could be like the Command Spells in Fate Stay Night. A trainer might use a Pokeball to summon and control a powerful 'Pokemon - Servant' hybrid. And the different regions in the Pokemon world could be the battlefields for the Grail War. The trainers would travel around, catching and training their unique Pokemon - Servants while competing for the Grail.
A possible plot for the 'stay night and apocrypha crossover fanfic' is a story of redemption. A character from 'Apocrypha' who has made some bad choices in their own story, could find a chance at redemption in the world of 'Stay Night'. They could team up with a character from 'Stay Night' like Shirou, who is known for his selfless nature. This would lead to character development for both as they face challenges together. Also, the different magic systems in both series could interact in interesting ways, like how the Reality Marble in 'Stay Night' might be affected by the unique magics in 'Apocrypha'.
One idea could be to explore what happens when a new and very strange artifact is added to the museum. Maybe it has some sort of magical power that affects all the exhibits in unexpected ways. For example, it could make the dinosaurs start speaking in modern languages or the statues come to life with different personalities than before.
A plot could be that Mordred is summoned by a powerful ninja as a last - ditch effort to fight against an ancient evil that has emerged in the Naruto world. This evil has powers similar to some of the powerful Servants in Fate Stay Night, so Mordred's expertise is needed.
Perhaps a story where a secret society meets only in the dark of night. The main character stumbles upon their meeting and gets drawn into a world of secrets, power struggles, and ancient rites.
One idea could be exploring a different origin for the vampires in the 'Twilight' universe. Maybe they are not just a natural occurrence but were created by an ancient magic gone wrong. Another could be a story where a human character has the power to control the elements and how that changes their relationship with the vampires and werewolves.
One idea could be exploring Mae's life before she came back to Possum Springs. Maybe her experiences in college that led to her dropping out. Another could be a story focused on Bea's family business and how she copes with the added pressure. A third option might be a time - travel fanfic where Mae goes back to a crucial moment in the town's history.
Perhaps a group of misfits, who are all outcasts in their normal lives, are brought together in 'escape the night'. They initially don't get along but as they face the various deadly challenges, they learn to work together. They find out that there is a traitor among them, planted by the 'evil force' behind the 'escape the night' ordeal. They have to figure out who the traitor is while also trying to escape.
