Is there a name for the trope where a story is high fantasy at first glance, except for it's not fantasy and is actually set in a post-apocalypse dystopian future?
I'm embarrassed to say that I have encountered this, this particular type of story on multiple occasions... So I got curious, is there a name to this trope?
That wouldn’t fall under a single trope, but would be a combination of several tropes. After The End would be a requirement, and for technology that is like magic to those who live in the world would be Lost Technology.
