(at this point not sure of the numbering)
* The Imperial City was actually laid out as a giant arcane sigil and is powered by the lives of the people in the city. It is meant to bless the empire and keep it safe from incursions by the extraplanar forces that wiped out the last civilization. Unfortunatelly the secret long held by the Imperial Dynasty was lost 20 years ago when the last Emperor died without an heir. The Imperial Senate sees no need to maintain antiquated building and zoning laws and has begun to a major renovation project of the city.
* The Saint that Ascneded and is now worshiped as a god did not in reality Ascend. His bones are in a secret shrine beneath his temple.
* The city is actually inside a bottle on the shelf of a powerful wizard. The surounding countryside is an illusion. Food and water are conjured when they are brought into the city. New arrivals are actually enemies of the wizard who have had their memories purged and replaced by false lives before being teleported into the jar.
* The gods are all dead. Clerics have found a way to transform the faith of the people into magical power. If the truth was ever known not only would it mean the end of their power, but probablly the end of civization.
* The reason everyone in the empire can read? A virulant intelligence is nesting in the population and is transmited through the written word. This is only its larval form, however, and one day it will awaken and transform the populace. Into what no one knows, but the king pays a great deal to discreet wizards to try and find out.
* Goblinoids once ruled the world and used humans, elves, and dwarves as slaves. These races made a pact with a powerful god to throw the goblinoids down and set them up as the masters of the land for 333,000 years. Time is almost up.
