On my first, half-paying-attention, read, I thought you were talking about a new gameplay mechanic like a timer that counts down to the end of the world. Like going full Majora's Mask and the moon is falling. But then on my 2nd read, I realize it will be a plot twist and I reset my expectations. All plot twists cause fan discourse and discussions and if they don't, then they failed at being a plot twist.
And one compliment before I go is how you keep doing things with RPG maker that keeps blowing my mind. First was a slot machine, then doing a predator mechanic, and now this. I'm no game designer and I don't know the limits of RPG maker, but I am seriously impressed.
