Alternate realities and parallel earths has been a staple of storytelling since HG Wells’ The Time Machine. There is something intriguing about asking “What if” and exploring possibilities of what would the possibilities be if something that happened, instead happened differently. Exploring these possibilities can make for some very compelling stories if handled correctly.
One Event That Changes Everything
One of the fantasy stories I am seeking publication for deals with an “alternate present” which is a normal, modern world that had a singular event in the past change the course of history. Perhaps you can introduce a new circumstance into the world you’ve created, which alters the world and creates a new set of circumstances.
Start At the Ending.
Another approach is creating your alternate reality and highlighting the current differences from your original world, then going back and explaining how those changes came about. This is a good option when you already have ideas for how your alternate reality will be portrayed. Just go ahead and preset the ideas you have, then go back and explain how everything came to be later.
The Butterfly Effect
Sometimes creating an alternate reality is as simple as taking a decision one of your characters made and asking yourself what would ave happened had they made a different choice. This has been the basis for many alternate timeline stories from Marvel and DC.
An easy way to do this is to take a decision or action that was taken in the story and have your character do something else, maybe even the exact opposite of the action. That will create the catalyst for your world to change.
Ripple Effects
However you choose to approach your new alternate world, it would behoove you to do a deep dive into your new status quo and truly flesh o the details o how that world operates an how people operate within it. I advise creating a bible or appendix explaining as many details about your world as you can muster up. This will serve as the reference point for your world and establish the new rules and parameters of that reality that you will abide by as you craft your story. How is the flora and fauna changed in your new reality? How are economics and politics affected? How do people live and coexist?
Whether it be the goatee-clad evil alternate Star Trek characters, or the many alternate Earths in the Marvel and DC universes, exploring alternate realities is a great way to come up with and develop new story ideas.
