Nick and the Big-ass Demon

I stood in the middle of the road, peering through the evening's foggy darkness as the moon watched, nervously from her perch in the sky. Across the field, to the east, the trees shook. I held my spear, an old dowel with a point whittled on one end, tightly in my hand and took a deep breath. I could hear the rush of water from the river behind the trees and the sound of heavy breathing, but not my own. The rasping breath seemed to struggle as it dragged air into its lungs. A choking growl came and the leaves trembled.
To the south, a bit of light began to grow and an engine revved. I took a few steps back, keeping my eyes on the far branches as a large truck, roared down the road. I turned my eyes away as the bright lights zoomed by. I raised my head again, and watched as truck's red lights dwindled, finally disappearing around a bend in the road. I turned my head back to the treeline.
"Come on," I said, in a hushed tone. The moon took refuge behind a cloud. My eyes readjusted to the darkness quickly. The brambles across the field gave a violent shake and a black mass shot into the sky. It reached the acme of its height and a pair of broad, leathery wings erupted from its back. It floated down to the ground, landing with earth shaking force, despite its attempt at grace. As the creature landed, the moon reemerged, revealing a pair of beady black eyes, resting in a giant head. Atop the head were two horns, one broken, the other long and curved, like a wildebeest's, and a pair of pointed ears, like those of a bat. Below the eyes, a pair of narrow slits opened and closed as the cool night air was sucked in and out of the monster's lungs. The rest of its body was much like that of a twenty foot tall man, save for the hooves, which dug deep into the grassy field.
"There we go," I said. "How are you, Caldar?" The beast said nothing and drew a giant, gnarly scimitar from a sheath on its belt. It stepped forward, shaking the ground with each stride until it stood in the middle of the road, blocking out the moonlight, casting a giant shadow on me.
"I'm tired," the beast grumbled. "What do you want?"
