For other versions of Underfell, see Underfell (disambiguation).

Storyfell (also known as Shiftfell) takes place in an alternate universe that is the combination of Storyshift and Underfell. The underground is in bad conduct under the slothful rule of Sans. The plot reaches to other AUs.


This story follows under a time of stagnant in-progression where the Underground is left to ruins causing the monsters to turn to any means necessary to survive. A operative order of things soon came to pass given the idealism to Control or be Controlled. Monsters turn at one another. Asgore, the royal scientist minutely covers things over the Underground while took control over it. Thus is prior to the Protagonist's arrival.
