Sorry to get back to the subject... You don't realise the scope of the work I'm doing here, yet, and I'm not giving any spoilers, but, I can tell you about my method of creation without damaging the future interest for any reader that wants to follow A little bit of blue.
(As an author's note, I also point out that I did give deep thinking of what kind of changes there may come in the evolution of religions and the confrontation of civilizations, including the epistemological ruptures that may arise from a global scale destructive event and further considerations about what social structures have the strength to survive global chaos. You can see, here, that a female hero is leading a (post-apocalyptic) muslim community, which is, in itself, a paradigm shift. You should consider such story traits when reading this type of a story.)
Regarding my method: I work with images, as that is the way my brain processes language. In this eidetic process, I have schematized a full universe and got that schema on paper, as a simplified diagram, so I can re-structure this world, in my mind, whenever I write.
Then, I noted a dozen or so predictions of what would arise in case a nuclear war started next week and imagined a basic storylline, out of the infinite number I could develop on that universe.
Then, In the spirit of freewriting, I am populating this world in short, ten to twenty minutes writing sessions, only attaining myself to the rules of this universe I have set in my mind. Also, I have made sort of a free schematics of the characters arches to guide myself in their development. And, writing goes as the moment's flair, or inspiration dictates. Before publishing, I only recheck if I am following the universe's rules and if I am not deviating from the character's arch in a great extent, and correct as needed.
I believe this will allow me to achieve a very organic story in an interesting, coherent universe, that really has no need to have any relation with our actual reality. (It is a product of imagination, after all...). If it doesn't, at least I'll be left with a few cool self sustaining stories. :))))
This is in no way contradictory with your idea that Religion is in the end of days... Which I kind of agree with, if we are talking about so called Western religions. It just means that in this universe I created, religion is one of the features. And... A few will show up. :)))))
Thanks for the comments, @wakeupkitty ! :)
In the end, we'll have found out if it is possible to freewrite an entire novel. :D)))))
