This is an undertale AU that is made by myself, SatanicDemonToast and Spongebobsquidless. It is also a renamed version of Vertotale (we decided the name sounded too much like another similar AU). Enjoy!

This an Original Undertale AU Collab with @Squidguy7 This is an AU where the monsters won the war and trapped the humans underground. Sans must find a way to bring the monsters and the humans back together, but it will be difficult, the monsters despise humans for hunting any killing them, the humans are wary of the monsters from the bloody war. How can Sans bring the two opposing species together? Or will he have to choose a side? Well you will have to find out.......,
