The Lost City of Amdaphor and the Sineaters

[Anonymoose]

Does not the the transformed Sauldia retain some vestige of her personality before it slips away in a similar manner to Tesleen?

As mentioned in my second post, yes. But, again, it cuts both ways:

Succubi manifest on the physical plane by forcing their souls into the bodies of deceased women. Once the transition is complete, the resultant creature is said to be both fair and fey to look upon. Still more disconcerting, researchers claim that these voidsent occasionally exhibit the personality traits of their deceased hosts. Succubi occupy the third and fourth rungs of the voidsent hierarchy.
