World-building-heavy trilogies I've read, primarily in science fiction, fantasy, and dystopias. I'm talking maps, magic systems, political systems, the lot. I'll take suggestions, but will need evidence/verification from a few other sources or will need to read them myself. Prequels or standalone books set in the same world will not be added, unless they come in a trilogy version of their own. Also taking suggestions on emojis because I don't know what fits well here lol
