Night Hags

Sly and subversive, night hags want to see the virtuous turn to villainy: love turned into an 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.
Soulmongers. While a humanoid sleeps, a night hag can straddle the person ethereally and intrude upon its dreams. Any creature with truesight can see the hag’s spectral form straddling its prey. The ethereal hag fills her victim’s head with doubts and fears, in the hope of tricking it into performing evil acts in the waking world. The hag continues her nightly visitations until the victim finally expires in its sleep. If the hag has driven her victim to commit evil deeds, she traps its corrupted soul in her soul bag for transport to Hades.
