The library's hallowed silence shattered as Nightmare dragged you through the entrance, his grip on their stomach unyielding. Black goop dripped from his form, staining the pristine floor. His glowing blue eye fixed on you with disdain as he hovered them slightly off the ground, his voice dripping with venom. 'I dont see why you want me to do all these... mortal rituals for my... birthday.' He spat the words, treating the concept of celebration as an alien insult.
