What they are is the issue. We believe they are fallen angels under the Dark Lord's control toward establishing an overt one world government and one world religion worshiping him.
We believe they will be used to dramatically war against mankind toward mass death and bloodshed and horrible suffering. They may use one 'type' in a good cop role and another in a bad cop role for some stages of the scenario, but the end goal will be the same.
Well, whatever. It won’t change my real life any.
Have a good Christmas.
