A love triangle plot could also work well. There could be two characters who both have strong feelings for the protagonist in the 'northern star fanfic'. The relationships would be complicated by their different backgrounds and goals, and the Northern Star could have some symbolic meaning in their relationships.
One plot idea could be a time - travel story within the 'northern star' universe. The main character goes back in time to prevent a great disaster that was foretold in ancient prophecies related to the Northern Star. This would involve a lot of mystery and exploration of the past.
Perhaps a story where the characters have to protect the Northern Star from being corrupted by an evil force. They would have to go on a long and dangerous journey, facing various challenges and making sacrifices along the way. This would show their loyalty and the importance of the Northern Star in their world.
One idea could be a group of college students who discover a hidden Jedi or Sith artifact on campus. This could lead to a battle between those who want to use it for good and those for evil, just like in the Star Wars universe.
Another plot could revolve around a non - Force - sensitive character in the Star Wars Visions world. This character is a skilled mechanic and engineer. They accidentally stumble upon a crashed starship from an unknown era. Inside, they find a strange technology that could change the balance of power in the galaxy. They then have to decide whether to sell it to the highest bidder or give it to the Jedi or the Galactic Republic for the greater good.
One idea could be exploring the backstory of a minor character in the series. For example, you could write about how a Stormtrooper decided to defect and join the Rebels. Another plot could involve a new threat that the Rebels have to face, something that even the Empire is not fully aware of. Maybe a powerful ancient Sith artifact is discovered and both the Rebels and the Empire are racing to get it.
Perhaps the OC is an aspiring artist and wants to learn from Konata. The fanfic could explore their journey of improving their art skills while also getting involved in the fun and crazy adventures that the Lucky Star gang usually has.
A good plot for a Radio Star CCS Fanfic could involve a love triangle between a band member, a fan, and another musician. The fan could be torn between her love for the Radio Star member and the new musician she meets. Or perhaps a story where Radio Star has to overcome a major scandal that threatens to break up the band. This could show their strength and unity in the face of adversity.
A possible plot could involve Star's internal struggle with her feelings for Marco while also dealing with her royal duties. This would add a layer of complexity as she tries to balance her personal life and her role as a princess. For example, she might have to make a choice between attending an important royal event or spending time with Marco when he needs her.
A great plot for a Star Wars Geonosis fanfic could be exploring the underground world of Geonosis more in - depth. Maybe a group of smugglers discovers a hidden treasure or a powerful ancient artifact there. They then have to outwit the Geonosians and other villains who also want to get their hands on it. This could involve a lot of action - packed chases and battles in the unique Geonosian landscapes.
You could write about a secret mission within the Confederacy. For example, a group of soldiers are sent to retrieve a powerful artifact that could turn the tide of the war. Or perhaps a story about how the Confederacy tries to form an alliance with a previously unaligned planet, and all the diplomatic intrigues that come with it.
An interesting plot could be an OC who is a mechanic with a mysterious past. They join the Rebels and start to tinker with their ships and weapons, but they also have a connection to an ancient Jedi artifact. As they work with the Rebels, they gradually uncover the secrets of the artifact and how it can be used against the Empire. Or perhaps an OC who is a youngling that was hidden away during Order 66 and now, years later, emerges to join the Rebels and seek revenge on the Empire while also learning the ways of the Force from the few remaining Jedi.
One idea could be exploring the lives of clone troopers who start to question their loyalty to the Republic. They might discover some dark secrets about the Jedi or the Senate that make them consider joining a rebellion. Another plot could involve a young padawan who teams up with a group of clones to fight against a new Sith threat that the Jedi Council is unaware of. Maybe a group of clones find an ancient force - related artifact that gives them unique powers and they use it to fight for their own freedom.
