So I have a couple things going on with this UnderTaleAu.

Like how it’s a post apocalyptic world, while the Monster where ironically safe in their underground prison the humans up above have been at war for a couple years. Followed with a Nuclear fallout, followed by an evacuation of the planet that left the 90-97% of the human population on the planet to fend for themselves. 

But as time passed and the Nature of the planet became new Humans and Animals began to evolve/adapt with their mutations as well as the concept of Magic and monsters being brought back. Blurring the line between Humans and Monsters.

Which was all fine and good, til the *original* Humans came back to reclaim what they lost. Bringing up this whole conflict on who is technically human, those who found refuge in space not really evolving much from once they left? Or those left on earth that have adapted to the environment and mutations?

Then that’s when the underground residence came around.

I also have stories i wanna throw in like, unethical breeding between monsters and humans for selfish gains, segregation, environmental issues, political stuff between humans and monsters, and maybe religion? Topics I’m sure to screw up on.
