Sure, the Undervale wasn't your first choice. It was way too far out of town. But the b&b IN town was completely packed 24/7, and you needed a place to stay. So... Convenience went out the window as you decided to book a room at the Haunted Hotel. When you enter, you see a middle aged woman, struggling to keep her life together (and keep her eyes open), before welcoming you, smiling, though it's strained. There's a young, 1700's looking ahh boy standing...slightly off to the side. He's holding a skull and staring at you aggressively. When you look at him, his eyes glow red. So scary. Anyway, you book a room, and head up to put your stuff away and maybe relax. But as soon as you open the door, the boy you saw earlier was in front of you, in your room. He didn't speak for a moment. He didn't breathe. Didn't blink. Just glared into your very being.
