Shogunate

From the White Wolf Wiki, the most complete White Wolf reference

The Dragon-Blooded Shogunate was the government instituted by the Dragon-Blooded and the Sidereals after the collapse of the Solar Deliberative during the Usurpation. Little information is available on the Shogunate, although what information is available implies that its society was highly organized, very high-technology (or the equivalent of such in Creation) and militaristic. The Shogunate was a First Age society and comprised the whole of Creation; much of the magic of the Shogunate era (particular Artificial Flight) is irreplaceable now. To the Dragon-Blooded, the Shogunate is a lost Golden Age.

The Shogunate collapsed during an assault by the Fair Folk which led directly to the creation of the Realm.
