Okay, I'll add what little I know. I'm certainly no demonologist, but I have been attacked by legion, and I took the opportunity to study them. Legion is as it says, they are many, acting as one. They are invisible to the naked eye. Somebody looking at that part of the iss without a digital video would not see the creature. They give off infrared light, and most digital cameras pick this light up as a whitish-blue color. They affect electrical circuits. As in the Bible and as seen lately in the news, they can and do affect certain individuals.
