This question already has an answer here:
I have been following worldbuilding for quite sometime. I am writing a fiction with a setup from ancient Indian mythology. It is an alternate universe where Aryans have dominated all the continents and then somebody in a small town discovers the magic. There are so many ideas I am having but all I need is some kind of a framework or some book which can be followed to create the world. Basically I am looking for some book so that I can organize all the ideas in order to build a magic realism.
