Summaries... my worst nightmare...
Anyways, the characters of this book are not mine, they are from their creators of Undertale, Underswap, Underfell, etc. etc.
Ever since the Alternate Universes of Undertale found out about each other, they started to come together in one place that lets all monsters from all Universes in. Only a few do stay there.
Cover Art was created by me, DO NOT USE IT FOR ANYTHING ELSE, thank you.
