   Summary

   Countless timelines. Infinite universes. All a hair’s breadth away from each other. There are names for them- “Underfell.” “Underswap.” “Aftertale.” “Outertale.” Far too many to count.
   Have you ever wondered, human, what would happen if those timelines were to collide? If those fragile boundaries disappeared, allowing all the denizens across extensive universes to interact? Does the answer to that question frighten you?
   …
   God. Fucking. Dammit.
   The answer is selfcest. Holy shit. So much fucking selfcest. Seriously, who let these kinky fucks ever meet each other? Honestly, what did you expect? Slam a bunch of horny skeletons together, and assume that they won’t immediately start fucking each other? Please.
   So, here we are. Drama, comedy, romance, tragedy, etc., etc., etc.
   Featuring the engrossing love story of a nerd and an edgy fuck, the heartwrenching romance between a stoner and a blueberry, the antics of two useless ass skeletons, and much, much, more.
   This is a fucking mess.
