There is no certain qualification or a course that one can do on world building; however, every story requires world building. It does not matter if your story is set in an imaginary place or in a real place, you will have to come up with characters for the reader to suspend doubt and be able to engage with your story fully.
The more difference we have in our world, which you introduce, the more you have to focus on having the details correctly. You need to do this in a way that they will almost fade into the background for the reader to pay more attention to the story and the characters. It would be wrong for you to create and explain all the aspects you have in your world in the first chapters. If the story does not develop in these few chapters, then the reader might not persevere in reading the book further.
For you to become a great world builder there are some things you should consider before you write a book. Below are some things you can consider before creating your story.
You should know what is important where you are. It is important for someone to have the main thing that is happening in a particular place at that moment or happened earlier. When creating your story, you should relate it to a real-life situation. This way, most people will be interested in reading your story because it can be used for remembrance, educating people or entertaining.
Create an imaginary world. Creating the imaginary world is a hard thing for most writers. Most people create an imaginary world in science fiction and fantasy. Here the writer invokes up from scratch every information of a world history, language, characters, social, customs, religion, politics, and many more. The thought of coming up with all these things to form the whole fictional world might be daunting, and deciding where you can start might look impossible.
One should be able to decide where he or she should start narrating the story. Not all writers have the capability of attracting the attention of readers. It is important for someone to have an interesting thing at the beginning of the story. Make sure, you make the reader peruse the next pages to read the story more. It is possible for a reader to stop reading the book after reading the first few pages. This is because some stories are poor for one to continue reading or it is possible for someone to know what the other chapters are talking about.
