Halloween (being)

Halloween is the name used by the unnamed supernatural narrator of the short story I Am Halloween.

History
The unnamed narrator of I Am Halloween is implied to have existed for centuries, witnessing the development of the human race. Recently (implied to be several hundred years) it has lived underground somewhere in a rural area with no human development, apparently hibernating all year under October 23, a day of "great power" it refers to as My Day. According to the narrator, My Day is anniversary of when "An insane, power-hungry beast managed to doom her entire species," though this is not explained within the story. On My Day, this creature was joined by a horde of other supernatural entities to enjoy a drug-like euphoria that occurred naturally for them once a year.

Sometime in the twentieth century, humans came to settle the area, starting with a single couple and their two children. When the humans arrived, the narrator's supernatural comrades fled, believing humans had the power to make them cease to exist simply by denying their existence. The narrator stayed in the area, avoiding the humans, and was devastated to realize that their presence had cost My Day its euphoric bliss. He continued trying to feel the euphoria by himself, but was unsuccessful.

Over the years, the narrator watched the family (later joined by other families, who built their own homes in the area), eventually discovering that they observed a supernatural-based holiday eight days after My Day. He learned that this holiday was called Halloween, and decided that the humans must have started observing it as an alternative to the dangerous October twenty-third. He began planning to perform his old ritual on Halloween instead of My Day.

On October thirty-first, 2015 A.D, the narrator left his underground home and walked around town in the shadows, avoiding the trick-or-treating children. He met a little boy dressed as a zombie and spoke to him, discovering that the boy did not have the power to deny his existence, and that he assumed the creature to be a man in a costume. The creature killed and ate the little boy.

Over the next year, a new family built a home on top of the creature's lair, and he continued living in the rarely-used basement. Next Halloween, he openly walked into the crowd of trick-or-treating children, relishing the knowledge that they were all slightly uncomfortable with his appearance, and that deep down they lived in fear of the supernatural.

Physical description
Halloween describes himself in the story as being very tall and thin, wearing clothes, with razor-sharp teeth and black eyes. To the untrained eyes of the children, he appears to be a man in a costume. In the image on Nathaniel J. Nelson's website, he appears as a tall and stick-thin humanoid covered in hair, with wide lips and pointed ears.
