Tales of the Louisiana Bayou

The Louisiana Bayou. It's dark in the bayou and there are strange sounds, cries, glowing lights that drift in the mist, and shadows blacker than night. And black pits of tar from which ungodly horrors crawl. Is it the Swamp Witch or something much darker? Is it voodoo or something inhuman? Some folk whisper of such things, but most stay quiet for fear that something may come for them in the night.
