I've looked through the archives, and searched the internet to no avail. I'm writing a story where the main characters are attempting to catch a cauchemar (Nightmare Witch). I found a reference to the fact that cauchemars can be contained in spirit jars, but I cannot find anything else detailing these jars.
If it matters, the story is set in New Orleans.
Help? Does anyone know anything or can someone point me towards a source for information?
