Moa'ah

"... Moa’ah ... A kind of demonic afterbirth unique to this region of the American South. I have not seen its like since the Civil War battlegrounds. When angels and demons skirmished over the souls of the dead...You don’t understand, Moa’ah is a footnote in the Luciferian apotheca — one of its most obscure calling cards. It shouldn’t exist anymore. Its very presence here is a harbinger of the Apocalypse. And the Witness knows this. He wants us to know it."

- Castiel about The Moa'ah

"... Moa’ah’s the animating force behind every bad kind of mojo you can imagine. Like the fuel that makes it go. Sounds like your dead Civil War soldier must’ve gotten some on him when he wore the noose."

- Bobby about The Moa'ah
