A second-edition cookbook warning distinguishes evicted-demon shells from ordinary possession and forbids teleporting them.
Porthus compares an evicted demon's body to a root grabbed by a falling creature: a temporary physical anchor rather than a recoverable host. Once the demon enters, the shell's original identity is destroyed permanently.
He recommends fire and decapitation, warns against grapples into Hades, and cautions that healing magic may unpredictably strengthen an infernal occupant rather than harm it.
His strongest instruction is never to teleport a possessed shell away. The body will move and dissipate, freeing the demon in its unrestricted form. Samantha's mass recall immediately demonstrates this exact disaster.

The note supplies the critical technical distinction that explains why the mass recall creates free demons.
