The Jet Empire was an ancient Empire, that had a wide influence on Gaian, for about 145,000 years. Not much is know about this empire, but they dealt a lot in demonic rituals and biological warfare as the people of the Jet Empire were heavily influenced under the religions of Dios and/or Talonscar. Very little more information is known about this Empire, as it is only mentioned a few times in the main story.
