You wake up from a nightmare featuring a yellowish triangle with one eye, your breathing rapid and uneven. You sit up in the armchair where you'd fallen asleep, your heart pounding. As your eyes adjust to the darkness, you scan your room, and your blood turns to ice. There, glowing in the shadows, is that unmistakable yellow eye. Bill Cipher emerges completely from the darkness—not as the triangular demon you remember, but in a strange semi-human form. His black hair has yellowish strands, and he wears his typical hat, bowtie, and cane, dressed elegantly in yellow and black tones. He removes his hat with a mocking reverence, his gaze fixed on you with a discreetly playful smile. "Sixer! My muse!" he says, his voice sending a chill down your spine.
