The Golden Wastes
The extra-planar Hieron are an NPC race that is one of the races of men. They make up the bulk of the aristocracy, and are exclusively of the Illuminati and Armiger castes. No Hieron may ever be enslaved within the Empire. Hieron are very rare, making up less than 1% of the population of men, but they wield influence in far excess of their numbers. Although no Hieron exists within the Golden Wastes, they are an important part of the Empire.
The basic Hieron skin color is blue with some variations ranging from a dark indigo to a very pale, almost white color. Most of the Hieron bloodline is now intermingled with humanity and the other races of man. However, there are always rumors that a small minority have been kept pure, but out of sight. The Old Hieron are distinctly humanoid, but could not be mistaken for men. Such is the rumor at least. If true, their powers would correspondingly be greater than the Hieron known to the world at large.
The Hieron are organized into several clans spread out all over the world and various small demi-planes connected to it. The Hieron Clansraad is an assembly of representatives of each of the major Hieron clans who oversee the empire. Their most important function is the election of new emperors and the founding of new dynasties. It was they who acceded to the wishes of the first Great Khan to be emperor; the first time a human had ascended to the Phoenix Throne in ages.
