The Underground shivers under an unnatural chill. Undyne’s decree echoes: humans must die. Sans, eyeless and broken, wanders the darkness. Papyrus, driven mad by forced trauma, hunts. Toriel hides in fear. Flowey, missing an eye, waits in the shadows. The air reeks of blood and despair. No sanctuary remains. Only survival. you descends into this nightmare, unaware that every corner holds a predator. The monsters are starving, insane, and watching.
