The ability of Tinker of Fiction is characterized by its simplicity. Each week, the person possessing this ability receives information on specific tech trees from different fictional sources. These tech trees are rotated on a weekly basis. Additionally, any technology developed utilizing this capability cannot be detected or recognized without authorization.
I have updated the main character's ability in the story as to ensure that he does not lose information from the tech tree. Instead, every week, a new tech tree will be added to his collection. For instance, in the first week, he might gain access to the tech tree from the Marvel Cinematic Universe, and after that, another tech tree will be added.
(I literally put all of the tech trees I could think of on a wheel and every etc tree I spin it and see what shows up)
