Another plot idea could be a time - traveling adventure. What if the characters from 'the thief lord' were transported to a different era? They could face new challenges and learn different things about themselves and their relationships.
A third idea could be a crossover with another story. For example, if the characters from 'the thief lord' met characters from a fantasy world, they could exchange skills and knowledge. The Thief Lord could teach the fantasy characters about stealth and survival in a city, while the fantasy characters could introduce magic or otherworldly concepts to the 'the thief lord' gang.
One idea could be exploring the backstory of the time thief in more detail. Maybe they have a tragic past that led them to steal time. Another could be a story where the characters from the original work team up to stop the thief from stealing time from a particular important event or person.
One idea could be that the thief has a secret noble cause. Maybe they steal to return precious items to their rightful owners who were wronged in the past. For example, an artifact was stolen from a family long ago, and the thief is trying to make things right.
Perhaps the thief is actually a misunderstood character. In the fanfiction, the thief could be stealing to save his own family who are being held hostage. Sasuke and Sakura initially pursue the thief but end up sympathizing with his situation and decide to help him instead.
One idea could be exploring what would happen if Percy had a different set of powers. For example, instead of water powers, he could have some form of earth - based powers. This would completely change his interactions with the other characters and the challenges he faces. Another plot could be about Percy's journey in the Underworld if he had to go there alone, without Annabeth and Grover. It would be a much darker and more dangerous adventure, full of self - discovery.
Perhaps the gamer could start a new fellowship, not to destroy the One Ring but to study and preserve the magic within all the rings. They could travel across Middle - earth, gathering knowledge and artifacts related to the rings, facing challenges from both Sauron's forces who think they are trying to undermine their plans, and from those who fear the power of the rings being misused.
Perhaps Sabrina discovers a long - lost prophecy that links her to the Dark Lord in a way neither of them expected. This could lead to a journey of self - discovery for her as she tries to understand her role in this new revelation. They might have to form an uneasy alliance to face a greater threat that the prophecy warns about. The interactions between them would be filled with tension, mistrust, and moments of unexpected understanding.
One idea could be a girl who is stranded on the island before the boys arrive. She has managed to create a small, hidden shelter and a basic system for survival. When the boys show up, she initially observes them from afar, trying to decide if she should reveal herself. Her presence could change the power dynamics and the way the boys interact with each other.
One idea could be exploring the backstory of the dark lord before his rise. Maybe he had a tragic past that led him to embrace the dark side. Another could be the perspective of those who oppose the dark lord's rise, their struggles and secret plans to stop him. A third idea is to create a new character who gets caught in the middle of the dark lord's rise and has to make difficult choices between siding with good or evil.
Maybe the fanfiction could explore the backstory of the Lord of Darkness. How he came to be, his early life, and what led him to become the dark lord. It could involve a tragic event that turned him to the dark side.
A possible plot could be that a hobbit, who has a very charming personality, accidentally gathers a harem of female characters from different races. They join him on his journey, which is not just about destroying the One Ring but also about promoting unity among the different races in Middle - earth. This harem then becomes a symbol of hope and cooperation, showing that different races can coexist and work together.
