Okay so This AU dates back to the war between humans and monsters. Kinda. See, instead of a war between races, it was more a war between classes.

There was a virus going around and for a while, it was contained. However, they knew they couldn't contain it forever. As a result, they decided to build floating islands. The reason the islands were made was because the virus is heavier than air, meaning it just falls to the ground.

Well, they started evacuation of the upper class... and then the lower class caught wind of the virus. However, by that time, riots and shit started breaking out around the Transport Points. In the end however, most of the lower class got abandoned. Though there is no explanation as to how, exposure to the virus caused three things to happen to organic life;

Mutation Because of the virus, everyone exposed at least had mutations. Whether they looked cute or fucking horrifying depended on who was infected, what dosage, etc.

Notable Mutations: Sans, Toriel, Undyne

Deterioration Some kept their humanity as they mutated. However, others ended up losing it, or at least had it buried. These Mutations are much worse off than the previous stage, but at least their mutations have ceased. They are of no danger of dying off due to the virus.

Notable Mutations: Shyren, Froggit, Aaron

Death ...Do I need to explain? The virus fucked with them so badly that they just ended up dying.

However, some people(the higher class, believe it or not) got injections when on the islands to keep them safe.

...Cue Frisk.

Frisk managed to get their shots and everything, and went playing where they weren't supposed to. They ended up falling off of the island. How they survived is a mystery, but they woke up in what is SUPPOSED to be Earth's surface, ravaged by years of abandonment and abuse from mutations. Some mutations retained their humanity. Such examples included Toriel, Undyne, etc. Others lost their humanity, though Frisk can try to bring it back out of them, meaning ones like Froggit and Shyren.

And instead of trying to cause another war on humans, Asgore's real goal is to attempt to take out a crew sent down to investigate the surface, while Toriel wants to pursue diplomatic relations with the recon teams in the hopes that they'll bring up the less mutated. However, a lot of them are pretty much raised to hate any pure humans, because they're mostly/all higher class people who had turned their backs on them.
