THE UNBAPTISED

Long enough amounts of time passed so that the infected populace completely forgot about the space station above, and this was made quicker by the parasites, who arranged for them to forget. Legends/myths and religions exist that treat the space station people as evil invaders, beaten back by benevolent heroes. They are blamed like the Devil for all the ills of society, like they have agents among us.

These agents have no souls, being un-infected. There is a native population on Pandaemonium like this, extremely small, that are allowed to exist. People are able to join them if they wish, bearing children that go un-infected. They exist like jews, a permanent, hated/feared/misunderstood underclass.

They perform tasks that normal people can't or won't, such as handling physical the physical parasites and tending to them. Thus they are not prey, but neither are they free.
