So, I'm in the process of writing my first big story, which is supposed to be the first in a series. The full story is called "Black Moon" and it's set in a fantasy world which has a very gothic and Victorian aesthetic, with some Steampunk-esque technology, mainly in the form of trains and more down-to-earth things, as that aspect isn't the focus. Anyway, I'm here today asking for ways to make this world more interesting, like, what details I could have or mention that'd add to the world without specifically showing or telling every little thing. The three main locations I currently have planned for the characters to traverse from their starting point to their destination are: A huge desert, a diseased and insect-ridden forest and a town of cultists. Should I have any other major areas to this world in this first story? What sort of locations would fit the overall theme and aesthetic? I specify that, yet there's a desert, which has nothing to do with any of the ways I described this world If anyone has suggestions on what I could add or change to what I mentioned here, feel free to reply, and thanks in advance.
