I'm just mentioning everyone who replied (I think, if I missed you I'm stupid lol forgive me)
Storyhoppers are those who choose to go into stories or take what they want from them. They can gain allies, workers, items, whatever they want. They may experience the world of any story, even the ones they have written. Though nothing can be insane and exploited, characters may pick and choose what they want, though their actions may have consequences. Anything and everything is possible. Good luck
