What happens to exorcised demons such as legion?

In various religious and spiritual beliefs, exorcised demons, such as Legion from the New Testament, are often thought to be cast out of the possessed individual and sent to a place of confinement or punishment. In the biblical account, Legion was expelled into a herd of pigs, which subsequently drowned in a lake. This suggests that exorcised demons may seek new hosts or be eliminated, depending on the narrative. Ultimately, their fate varies based on the theological or cultural context in which the exorcism occurs.
