Dark Priestesses are upper-level demons that can bestow great power upon those who they bind as husbands and wives. Using a Dark Binding ceremony, powerful Dark Priestesses overwhelm good individuals with evil and pollute their family lines with darkness. These demons have forsaken their own ambitions of power and dedicating themselves only to the promotion of evil. Dark priests are "shielded" from the radar of beings of light that allows them to conceal their deeds.
