Detritus, Moe and K.Z. visit with faeries and an angel. As I understand it faeries were angels originally. They were the ones who thought Lucifer’s revolt was nothing to be concerned about and so neither joined it nor fought it. So while they fell with Satan’s forces their descent stopped at the Earth. Of course, that’s a christian explanation for faeries. I can’t remember what the original pagan explanations were. Or if they had them.
