As a little side project, I entertain myself with the idea of writing fiction that blends fantasy and mega-structures engineering.
The first step will be to ideate a consistent magic system, but of course, to make the story interesting, I'll have to come up with interesting characters and their conflicts. Do you know about any good story, long or short, that revolves around or has as background mega-structures, that I can be inspired from? Fantasy or extreme science-fiction would be the best.
