One idea could be a story about a young, inexperienced crew member on a voyage to the stars. They encounter a strange alien species that at first seems hostile but turns out to be in need of help. The crew has to decide whether to trust them or not.
Maybe a fanfic where the voyage to the stars is actually a mission to find a new habitable planet for humanity. Along the way, the crew faces internal conflicts, like power struggles and love triangles, while also dealing with external threats such as asteroid showers and malfunctioning ship systems.
Key elements would be the journey itself. How long does it take? What are the different stages of the voyage? Another important element is the relationship between the crew and Earth. Do they receive messages from home? Are they cut off? And of course, the unknown. There should always be something new and unexpected in a 'voyage to the stars fanfic', whether it's a new type of star system or a mysterious signal that leads them off - course.
One idea could be a fanfic that focuses on the backstories of the minor characters in 'Sea of Stars'. For example, exploring the life of a random villager before the main events of the game.

Or a fanfic that imagines an alternate ending to the game, like the heroes failing in their mission and how the world would be different as a result.

A time - travel plot in a Precure All Stars fanfic could be really cool.
