Undertale AU. How about instead of the monster losing, they won? What if humans were the ones trapped in underground instead? What if... Humans and Monsters switched places? This world is where all this happens. Humans and Monsters switched places. The monsters never existed underground in Mt Ebott, but humans are. Instead a human falling to the underground, it is a monster falling. What will happen I wonder? -------- Heya guys! This story is an AU of New Soul's Tale and Undertale! Don't mix it up with HumanTale, where monsters become humans. This is where the humans and monsters swapped places, not change species/appearance. The six souls are mine, kay. NO STEALING MAH OCS!
