Once upon a time, there were two races, Humans and Monsters. Eventually, the two races met and the monsters and humans started to merge societies. One day humans and monsters started to breed with each other, when the cross souls grew up humans realised they were in danger as the cross souls had various monster qualities such as magical abilities, and most interestingly, a soul that is a merging of both human and monster. Humans next learned that in vast numbers, these cross bred monsters could defeat and absorb human souls, as their souls are both human and monster. The humans declared war. At first victory was Imminant for the humans, when suddenly a hero to monsters emerged from their main base, who would soon become Asgore's General and command his army, for a while the monsters were winning, but eventually the humans were victorious. After the war the General retired, some say he had enough of war and battle, some say he was getting old and frail, some say he was just really lazy, and all those theories are correct in one way or another. The humans offered some of the cross breeds sanctuary if they sealed the monsters and other cross breeds underground. They accepted, and were soon after betrayed and tossed down with the rest of the monsters. Years later, anyone who is diagnosed to have magical abilities, regardless of the soul, is sealed underground. Meanwhile, Asgore has some willing sacrifices in his new cross breeds, but as they soon find out, their determination is the only thing keeping them alive, and when they sustain enough damage they turn to dust, just like any garden-variety monster, however, soon after their dust swirled into the air, as they came back from the dead.
-Hello everyone, thanks for being so enthusiastic about this new AU on Undertale Amino. If by chance you stumble onto this and you've never heard of Undertale Amino, it's basically an app for mobile phones that has a friendly and enthusiastic community who made this AU possible.
This story is inspired by many other works and may bear some resemblance in certain places. However, I will endeavor to make this story it's own.
2 years ago monsters were released from the underground, ending their centuries-long imprisonment at the hands of ancient humans.
Not a soul remains in the underground.
But that doesn't mean no one's there.
Be it chance or fate, The First Fallen will soon meet an all too curious human as he ventures into the deep beneath.

I apologize if this bothers you it's just how I've always seen the character.
Disclaimer: I don't own these Chara-cters nor do I own Undertale. This is just for fun.
