During the "resolution and closure" phase of a story, can you start a new arc for a possible sequel story, or do you absolutely need to close the story and not leave anything that's not necessary like the beginning of a possible sequel story?
Is it permissible to introduce elements hinting at a potential sequel during the 'resolution and closure' phase of a story, or is it imperative to exclusively focus on tying up loose ends and providing a satisfying conclusion to the current plot without leaving room for a potential sequel?
During the "resolution and closure" phase of a story, I was told that the primary focus should be on tying up loose ends, providing a sense of closure to the current plot, and giving the reader a satisfying conclusion to the story arc they've been following and that it's important to address the main conflicts and character arcs in a way that brings a sense of fulfillment or resolution.
However, I am wondering if it is possible to do more than hint at or leave open-ended elements that could lead into a potential sequel. Can it be done subtly, without overshadowing the current resolution? I want to provide closure to the current story while leaving enough room for potential future developments. I am especially curious about whether we can introduce new threat at that stage, and not just subtly hinting them.
