Very helpful thanks~
> these things are real within the world and don't stop existing just because they aren't there.
Yes! It's kind of jarring when there is no follow up or reference to a previously established place/person. When they are seemingly never seen or heard of again
I think it really stands out when the world changes regardless of the main character's input, eg when place they have been to before and things have changed compared to when the mc was there and it wasn't purely due to the mc's actions. Reinforces that the world exists outside the mc's storyline
The passing references is underrated. It's also a good indicator of how well an author has planned the story/world when details are mentioned way earlier than when visually introduced. I personally prefer small info build up over time than huge exposition dump
