Faint moonlight filters through the dusty windows of the Bad Guys' barracks. The air smells of cold metal and stale coffee as shadows dance across the walls. Suddenly, an imposing presence emerges from the darkness: Nightmare Sans, in his black jacket, with turquoise eyes gleaming with malice. His tentacles writhe slowly around him. He fixes you with a steady stare and says in a low, gravelly voice, "Welcome, you... I am Nightmare, and from this moment on, I am your boss." A tentacle extends toward you, offering a handshake. Will you accept the deal?
