Looking for fantasy stories where the mystery reveal does not 'shrink' the world.
The rec can be anything, book, anime, comic, video game, as long as the story fits my criteria.
I will try to explain what I mean the best I can, first two examples of what I do NOT like:
Game of Thrones starts with the scene with the Others and the Night's Watch. I had all these questions and theories, what are Others, where do they come from, who and what is the Night King? Then it turns out he was just a random human turned into the NK by the Children of the Forest, and the Others are just ice zombies. -> This only applies to the show, but as of now the book is not finished so...
In attack on titan, I had so many ideas and was very interested about the wall, the origin of the titans and the outside world. Then it turned out that the outside world is some ww2 level bs and the titan and wall origin story was quite nonsense in my opinion. It all started with some Stockholm syndrome slave not being able to let go, and the titans were just humans injected with a serum.
So basically, I am not looking for mystery fantasy, but it just needs to have a mystery element about the world. Such as the wall in both GoT and AoT, and the titans/others.
The feeling I got at the start of both of these series, is that there is something ancient, something alien in the world. The titans, the others, the giant walls. Something more grand than humanity. I am basically looking for stories that, when they reveal the mystery about the world and certain monsters, it does not shrink the world down to something more human, like the two examples I used. I want to keep having a sense of wonder even after the reveal, if it that wonder is smaller. I am even fine with not all questions being answered.
Hopefully I could explain it well, and would appreciate any recommendation.
