Note that things can be created as "side effects", including geographic features. The mountain or river, the town or the kingdom don't need to be the main aspect of your story or chapter. You can just write in your story about meeting a wise man in the mountains - and with that put those mountains on the map. The kingdom can be mentioned as a part of the background, but get created through that.
What is a Creation and what not does not depend on what is in the spotlight, but what you spend Prime on.
