Why this prompt works

Originally written for fan art of existing TV shows, this template is more useful, and safer, when you point it at your own world. It reuses the travel-guide structure (terrain map, miniature landmarks, white paths, labels and side checklists) but swaps attractions for characters and moments tied to each place. We invented 'The Lantern Isles', and the model produced a coherent archipelago with a Central Kingdom, Sky Temple, Frostpeaks, Ember Desert and Sunken Isles, plus lantern and compass props and a matching emblem. For game designers and novelists, it is an instant pitch visual. Replace every SHOW mention, including the bare one in the title line.

Tips

  • Describe 6–8 named regions yourself if you want specific places instead of invented ones.
  • Swap the TV-show 'official logo' line for 'an emblem matching the world' when using an original setting.
  • Don't use this for real franchises you don't own; the logo and characters are protected.
