I watched a short Ken Ham video where he talked of the need for a reformation rather than a revival. Its one of his points that you can't have a revival without the groundwork being laid, and right now, the groundworkis almost gone. Few churches and isolated in England preach the Truth, and many of them let corruption in.
Thus, an idea for a world.
Small, and isolated communities of a former Golden Age (that is now reviled by most as as the Age of Empire and Oppression).
The history of the world is taught that for millions of years, Demons and Foul Beasts ruled the world, but that one day, Humans arrived on the scene. No one is quite sure how, but most who think on it, think some sort of magical accident.
Humans lived as slaves of Demons for a long time, and then the Age of Man began (some say because Humans organized, and others because that was so, but that a Demonwar had broken the demons's powers beforehand).
There were then the Cycles of Empire as one group of rulers succeeded another, and as nations rose and fell, always fighting with the Foul Beasts and with Corruption and each other.
And then the Last Empire fell, the Federal Empire, and Man was once again opressed. So much so that Man again took unto himself the worshipping of Demons and the transformation of his body to the ways of th eDemons....so that some Men now look more like Foul Men than True Men.
They live in the ruins of the Empire, and trade and loot upon each other, and all as was and has been for a million years.
Except that most of that is a lie.
The world is 2000 years old. The first, Ancient Empire, was established by the Lords of Light.
Gotta go...gotta get my teeth cleaned by a dentist's hygienist. Sigh.
