The Constitution was produced at the dawn of the Empire, by the First Empress and her supporters. It is a set of axioms which dictate how the Empire can be governed and the rights of the nations of the Empire and their citizens. Although it is possible to change the Constitution, it is intentionally difficult to do so and impossible until The Throne is occupied. Even then, the NPCs of the Constitutional Court must ratify any changes to the constitution or to the way it is interpreted.
