>Now imagine the horror of Yoda and Obi-Wan restoring the entire Prequel Jedi Council as Force Ghosts. Imagine how much damage they could do.
lets not forget the voices of jedi past in TROS (despite how shit the movie is)

seemingly, the nightsisters have their own spirit realm, its where talzin goes when she becomes incorpreal (and stays around without a body after dying in son of dathomir) where ventress goes when she's buried as a ghost, the dead nightsisters are presented as ghosts in the same episode as well as the nightsister ghosts which can possess people in rebels, you also have the dead nightsisters lending their power to the living as presented in fallen order

the real question is why doesnt ventress' spirit pass into the cosmic force when she dies, and appears on dathomir as a ghost months later as soon as she's buried
maybe theres some form of "spirit trapping"? their spirit cant become part of the cosmic force because of some latent nightsister spell?
