Welcome to the Skeletale AU Wiki

Skeletale is a newer Undertale AU. It was an idea that began with a different AU, Incursiontale. After Regan Vance (the lead creator of Skeletale) started to help with making Incursiontale video game sprites, she had the idea of making her own AU. After getting the help of some Facebook friends, Regan and the others started the plotline that would soon be known as Skeletale. Details and the actual storyline (Found at this link- ) will be below.

What Skeletale is all about- Creating a new Alternate Universe

We want to let Undertale fans enjoy new AUs, and perhaps something to introduce new fans to. Skeletale is our first project to help make this happen. After seeing the same old AUs multiple times, we have decided to create Skeletale. To learn more, read the rest of the Skeletale Wiki.
