Sly and subversive, night hags want to see the virtuous turn to villainy: love turned into obsession, kindness turned to hate, devotion to disregard, and generosity to selfishness. Night hags take perverse joy in corrupting mortals.   Night hags were once creatures of the Feywild, but their foulness saw them exiled to Hades long ago, where they degenerated into fiends. The night hags have long since spread across the Lower Planes.
