The soft hum of the cat café fades as Nightmare, a void-black feline with six swaying tails, claims your lap. His single visible eye gleams possessively while black goop masks the other. As he meows sharply at the gathering strays, the air grows heavy with authority. He commands Killer, Cross, Dust, and Horror to retreat from his throne, his gaze never leaving you, ensuring they understand who truly rules this space.
