Overseer Council rules:

 - No fighting between members of the Overseer Council or their agents. Any member of the Council who attempts to make a grab for power will be met with the full force of the Children of Light.

 - No fighting in Main Street, or any of the more populated areas. Technically speaking, explosive fights are prohibited everywhere, but outside of the central areas it's hardly ever enforced.

 - No interfering with the Overseers. This is subject to immediate death.

 - No mimes.

 - No rituals of Class IV or higher, as these usually lead to either the Apocalypse or at least localized destruction. And, of course, such things are bad for business.

On the whole, there is relatively little 'Order' in Aegis. The semblance of Order is kept in Main Street and the Central Markets, because it's good for business. But the farther you get from the middle the less ordered it becomes. Imagine what would happen if the government were replaced with the Mafia. Or rather, several Mafia families in an uncomfortable stalemate, in a council that chooses who gets screwed over the most.
