I do not own Sleepy Hollow, The Headless Horseman or his horse, Daredevil. Pastor Otto is mine though. My description of the Horseman is based on Tim Burton's movie.

A Demon's Steed

Pastor Otto was a good man. He was a third generation pastor at the local church and a horse breeder. For decades, his family had been breeding white horses. Being a very holy man, Pastor Otto believed that the pure, white color of his horses was a sign of God's peace and spirit, white being a very pure color in his opinion.

One dark and cold night, Pastor Otto heard painful whinnying coming from out in the pasture where all of his horses were kept for the night. Knowing that one of his prize mares was very pregnant and due to give birth any day now, Pastor Otto just thought that she was in labor, and that he would wake up the next morning to see a brand new, pure white foal out in his pasture.

The mare did give birth that night, but with someone very dark and evil watching over her...

The next morning was cloudy and very foggy. Pastor Otto rushed out to his pasture to locate the new arrival to his prize-winning, white heard. What he saw chilled him to the bone. All of his horses were clustered in one far corner of the pen. Their body language told him that they were terrified, almost too terrified to move.

At the far corner of the pasture opposite the rest of the frightened heard was his prize mare, the one who had given birth the previous night. She was lying on her side, dead. Her face was frozen in pain and fear. Her once beautiful, pure white coat was covered in blood, yet there was no wound on her.

Grazing contently beside her was a brand-new, pitch-black male foal. He looked healthy and strong, and not at all afraid of anything.

From all this, Pastor Otto concluded two things: One, that this black foal must have been the son of his once prize mare, now lying there dead covered in blood. Two, that it wasn't his equally white stallion that had fathered the foal, but the Devil.
Before Pastor Otto could do anything else, a man about 27 years old walked out of the near-by woods. He had black hair that was kind of wavy and icy blue eyes. He wore a black cloak and had a long, sheathed sword hanging from his belt.
"Are you looking to sell that foal?" the man asked. When he spoke, Pastor Otto could see that he had filed his teeth down to sharp points.

"If you want him, you can have him," Pastor Otto said, taking a step back and clutching his Bible. "I want nothing to do with him! Take him away from me now! You won't have to pay anything."

"Danke," the man said. And with that, he tied a rope around the black foal's neck and led him away. Only once the foal and the man were gone did Pastor Otto kneel down to pray for God's protection and the other horses begin to calm down.
