Hope this is right subforum...
I've been working on future plot ideas for one of the projects I'm working on. I've had an idea that I want to use but I've run into a snag.
The plot idea is as such. The primary antagonist uses a ritual or spell (not decided on which yet) to cause an alteration in reality. This alteration affects everyone and everything, including the protagonist. However only the antagonist is aware of the change.
My question is how would I portray this alteration. Ideally, it happens in the middle of the protagonists day as the change sweeps across the planet. In a visual medium, I can see quite clearly who it would be depicted. But in a literary medium I'm having trouble coming up with the right way to present it that doesn't involve completely confusing the reader or over explaining the situation (and the changes made in the "new reality")
