It all happened on a foggy night in October

It all happened on a foggy night in October. Emily had been taking a walk by the trees, watching their shadows flow over her like water. Black water. As she thought this, the shadows turned to glass, and they were spinning, spinning into the form of some strange creature. "Hello," said the creature pleasantly. Emily yanked out her wand.

"Who are you?" she asked. Her hand shook.

"I have no name. I am a shadow, a rarity, a ghost of pain. I would bring misery, but, as I said, I am a rarity." Emily looked bemused.

"I'm sorry, but-but what I meant to ask was What are you?" she knew it sounded rude, but she needed answers. The creature seemed regretful.

"If I told you, you would not love me as I love you."

"You love me?" inquired Emily. The creature nodded. He did seem somewhat loveable, though strange and menacing. Could she find it in her heart to love again? After all, every time she had ever told someone she loved them, it had been a mistake. Would this creature care for her? The question seemed to answer itself. "You have to tell me who you are." The creature obliged.

"I am a dementor." Emily fainted.
