The dark creature slunk through the mists that wreathed the forest, its dark body blending nearly perfectly with the shadows. Its motions were smooth, fluid. Well, for the most part. Occasionally, the creature would pause, and one limb or another would twitch, spasm. Once the spasms had passed, the creature would shake its entire body, then continue on.
As it went, it frequently glanced behind itself, tongue flickering out, tasting the air. It had escaped, it knew, but there would be pursuers. And, it had determined, it was not going back. It had killed before, and it would kill again to retain its freedom.
