On hiatus. (Takes place after the True Pacifist ending) The barrier has been broken and all the monsters were free from the Underground. Most of the monsters have began to pack for the trip to the surface, but some monsters stayed behind afraid of the discrimination the humans would throw at them. Toriel is one of the monsters who decides to stay in the Underground with her newly adopted human child Frisk. Asgore Papyrus is ecstatic about exploring the human world, and Sans just wants to get away from everyting, but despite that he feels like something is off. The nightmares should have stopped after they got to the surface, but now he has them more frequently than he did before, leaving him exhausted and haunted by his past. Alphys locks herself up in the true lab and contemplate over turning core off or letting it run, and the decision to shut the core down or leave it running, because shutting it down could expel a powerful energy wave that could possibly destroy the Underground, but then she found something very interesting. She found that she could communicate with some other being using the core and her technology as a linkage to the void who makes the decision for her. Undyne worries about why Alyphs locked herself in her lab again. She would usually just wait for her to come out leaning against the wall of the lab waiting for the nervous lizard to emerge. Flowey The Flower currently is on a shelf in a plant pot, because Alphys still hasn't given up on finding a way to cure him. Book cover made by: Pandoriishi, so go check her out! Somethings to note: 1. There will be cursing in this. 2. Gore 3. Angst 4. Violence 5. There will be mature terms used in this and references. 6. Body horror 7. Science Sans used heavily
