Being possessed by a foreign entity seems very tame in the stories where I have seen it. The event doesn't have the gravity that I feel it should, and the person usually goes back to living a normal life if they are freed. I always felt that being possessed should be taken more seriously as a traumatic experience that people don't just come away with unscathed. I came up with an idea that I believed accomplished that.
Demonic possession is done through a magical ritual that can bind a demon to a human being, allowing it to cross over from their reality into ours. In the process, the demon forcefully bypasses the barrier that separates the soul from the individual, completely taking them over. The victim is left fully aware of their situation and is in constant pain while being possessed. The demon has access to its abilities in the host body (strength, speed, etc) but remains under the control of the caster. In a country where magic is commonplace, this is seen as a supernatural form of rape, the ultimate violation of a human soul. It is treated as one of the evilest acts an individual can commit on another person.
The victim was captured and subjected to this against their will, so people understand that. But while most will regard him as a victim, many would see him as corrupted and dangerous even after they are freed. They are forced to deal with the trauma of possession as well as being distrusted by others, even worse than murder.
I think this lends gravity to the situation and plays up the full horror aspect. But since it is obviously a sensitive subject, I wondered if this might be viewed as offensive or disrespectful. Does this premise take it too far, or should I just one with it? How can I present it in a way that it is taken seriously?
