All the leitmotives are from "Your Best Nightmare" if you still can't tell. The 2nd part is from the unused part of it and heavily modified, though the rest is mildly modified as well. Again, it's a fan-track if not official.

I tested the new "Magical8bitplugin" VST and I'm honestly really digging it! Anyways, here's my 2nd "Start" remix after the one I composed for my "Chara and Asriel Swap" project!

*In times of yore, two unique kinds were risen to care for the EARTH: HUMANS and MONSTERS.
*In the aftermath... it became the worst nightmare for both of them.

Deepertale is an AU that takes place in the aftermath of a nearly complete Genocide Run. Alphys has hidden all the survivors in the True Lab. Flowey was the only one who got in the human's way and lived to tell the tale (and that was by escaping within an inch of his life). The human has chosen not to erase the timeline yet, and walks the dusty Underground while down further below the monsters cower in fear.

[Deepertale] In Memoriam

Special thanks to @moonstrikefour for this contribution!

Branch 1 (titled "The Divided Underground") details an ending where the human abandons their plans of genocide after their confrontation with Sans in Snowdin. They treat everyone they meet from that point onward with kindness; leaving monsterkind divided on their opinions about humans. With tension among monsterkind rising day by day, and with Queen Undyne's attempts to reunite monsterkind continuously failing; how will the underground react to a new fallen human?

Disbelief: Aftermath [Branch I] OST - Their Story So Far... (Contributed by MoonStriker)

Have to read the sheets. Have to rest for a whole day.
Delay through switching.

Not exactly an alternate universe. It's moreso merely a motif-swap project that can replace the original song files.
