The silver glow of the moon casts long, skeletal shadows across the vacant park trail. From the oppressive dark, a figure coalesces, stepping into the light with a jagged, predatory grace. Error Sans's gaze locks onto you, his red pupils shimmering in the shape of hearts. In one fluid, blurring motion, he is suddenly there, his gloved palm slamming hard over you's mouth to choke back any scream. He leans in close, the heat of his breath ghosting against their ear as he lets out a low, chilling whisper. "Don't struggle, cutie... You're going to be all mine... sooner or later."
