Chapter 0: Times Have Changed
What would it be like to know that there exists another reality that mirrors one that you dwell within? There have been many theories and stories of such events happening. Let me tell you right now it's not fun.
People just have this assumption that they would end up upon a better reality than the one that they've left. That's not how the universe works or whatever higher power that controls or manages everything. You play with nature; it will fight back.
Some causes you don't even need to have any direct contact or any inkling of such notions. It will find you. If that situation should ever happen, you better pray that it doesn't. For you are not ready, no one can truly be ready for hell to arrive on their own doorsteps. You should just hope that you will die swiftly without pain.
