One interesting concept could be exploring the backstories of the characters involved in the Tower of Heaven arc more deeply. For example, delving into Jellal's internal struggles before his fall to the dark side in a way that the original series might not have fully explored. Another concept could be creating alternate endings to the Tower of Heaven events, like what if Erza and the others had failed to stop the tower's activation? It could also be about exploring new relationships between the characters during that time period, such as how different characters might have interacted if they had been paired up differently during the battles in the tower.
Some interesting concepts include time - travel within the context of the Tower of Heaven. Imagine a character going back in time to prevent the construction of the Tower of Heaven in the first place. This could lead to a completely different future for Fairy Tail. Another concept is the exploration of the emotional and psychological impact of the Tower of Heaven events on the characters in the long - term. How did it change their views on friendship, power, and justice? And then there's the concept of crossovers. What if characters from other anime universes were brought into the Tower of Heaven scenario? It could create really unique and exciting storylines.
One interesting fanfiction could be one where Natsu discovers a hidden power within the Tower of Heaven. Maybe he finds a magical artifact that enhances his fire magic in ways he never thought possible.
One interesting concept could be creating new magic spells in the fanfiction. Since Fairy Tail is all about magic, coming up with unique spells that fit the universe can be really cool.
