Apologies, I’m not sure if this is the right forum or not…
I’m not necessarily asking how to write a sequel. I’m asking about how to leave a story open for the possibility of writing a sequel or even turning it into a series (depending on the success of the original ofc). It is pretty clear in Hollywood at least, when a story hasn’t been thought through to the end, a sequel doesn’t quite fit, or unexpected success creates several seasons.
It seems a cliffhanger is one way of doing it. An unanswered question leaves room for multiple possibilities, but that wouldn’t work for a series. Is it something that needs to be seen throughout the original story in order to fit in? How do you make it all feel cohesive? The point of my question is to avoid it seeming like a sequel came out of nowhere and that it doesn’t fit with the original story.
And how does this compare with writing a story in the same world but is not necessarily a sequel?
