Another plot could involve Merlin traveling to the future. He might see a desolate Camelot, destroyed by some unknown force. Then he has to return to his own time and figure out how to prevent this dark future from happening. This would involve him using his magic in new and creative ways to influence the present to change the future.
A third plot idea is that Merlin accidentally travels to different points in time in a sort of time - loop. Each time he goes to a different time, he has to solve a problem related to Camelot's history or future. He has to break the loop by finding the root cause of this time - traveling chaos, which could be a spell gone wrong by an enemy sorcerer.
One idea could be that Merlin accidentally casts a time - travel spell and takes Arthur to the future. There, they see a world where magic is accepted and Camelot has become a legend. Another could be Arthur traveling back in time to meet a young Merlin before he came to Camelot. This would change their initial meeting dynamic.
One idea could be that Merlin and Elizabeth go back in time to Camelot's golden age. They could use their modern knowledge to solve ancient problems. For example, they might introduce new medical techniques that save lives. Another plot could involve them trying to prevent a major disaster in Camelot's past that they know about from history books. They might also have to deal with the cultural shock of living in a different time period.
One interesting plot twist could be that when Merlin and Morgana time travel, they end up swapping their magical abilities. So Merlin has Morgana's dark magic skills and vice versa. This creates a whole new dynamic as they struggle to adapt to these new powers in a different time period.
One plot idea could be Merlin and Nimue teaming up to save a magical forest that is being threatened by dark forces. They could use their combined magic to fend off the evil entities. Another idea is a time - travel plot where they are sent to the future and have to adapt to the new world while also finding a way back. And perhaps a plot where they are wrongly accused of a crime in Camelot and have to prove their innocence together.
One idea could be Merlin having to deal with the political intrigue of being a king. He might face challenges from nobles who don't trust his magic. Another could be Merlin using his magic in unique ways to improve the kingdom, like creating new irrigation systems for farmers. Or perhaps he has to form alliances with other kingdoms while hiding his true identity as a powerful sorcerer.
One idea could be that Merlin, as a wizard, is hunted by vampires because his magic is seen as a threat to their existence. But then he discovers that some vampires are not as evil as he thought and they form an uneasy alliance to fight a common enemy, like a dark sorcerer.
One idea could be exploring a different magical realm within the 'the merlin conspiracy' universe. Maybe there's a hidden land where the magic is more primal and ancient. Another could be a story about a young wizard who discovers they have a unique connection to Merlin himself and must use that to stop a new dark threat.
A plot could involve Merlin getting cursed and the knights having to find a way to break it without Merlin's magic to guide them. They might have to rely on old legends and their own wits to save him. This could lead to some great character development for the knights as they face challenges they usually rely on Merlin to solve.
One plot idea could be Merlin, as a borrower, is discovered by Arthur. At first, Arthur is shocked but then becomes intrigued. He decides to protect Merlin from the other humans in the castle. Another idea is that Merlin, in his tiny form, uses his magic in new and creative ways to help the borrowers' community. For example, he could create miniature tools or defenses against predators. A third idea might be that Merlin has to go on a quest to find a magical item that can restore his normal size, all while facing the challenges of being so small in a big world.
One idea could be Yoda traveling back in time to train Anakin Skywalker differently, thus preventing his fall to the dark side. Maybe he goes back to the very beginning of the Jedi Order to gain more knowledge about the Force and bring it back to his own time.
