Where it all began

Monsters weren't always living peacefully with one another underground and the humans didn't always have such a vendetta against them. There used to be a hierarchy that created a major gap between all the monsters based on their monster type. This story is supposed to be set in a time way before the humans let their fears consume them. Set in a time where war was farthest from anyone's thoughts. The main focus of this story is supposed to be on Asgore, Toriel, and Gastor, and how their experiences shaped them up to what we know now about them.
I also wanted to mention that all the monsters in this story are monsters but they have a more human feature. Like gaster, for example, has skin and hair and lips, and none of the furry monsters have furr all over them, like dogs for another example, wouldn't have furr but they would still be dogs with a head full of hair and Claws and sharp canines and ears and a tail with a bunch of chest hair obviously.
Asgore and Toriel wouldn't have furr all over their bodies but they have goat like features.
And just to be a bit clear, Gaster doesn't have normal skin like his skin is kinda see through and you can see his bones but he doesn't have any organs or blood vessels.
This story is gonna contain some violence and some curse words and death and some moments of prejudices. So if that bothers some of you please don't read this. The reason why I created this story was because I thought it would be interesting if the characters weren't always the way they are now and thought it would be a cool take.
Also bc I started to become obsessed with Steven universe so yea ndnsnd.
So with that being said please enjoy the story.
