The Emperor, or Empress in the case of the sitting high authority, is the unconditional ruler of the Jankan Empire. There have been many Emperor's over the years, including current Empress Geedin Manta and former Emperor On'sylivia. The latter was assassinated by the BlyDonian Civilization, an event that sparked the BlyDonian-Jankan War. The BlyDonians emerged victorious, and eventually it was up to the new Empress, Manta, to turn around the fledgling civilization into the powerful empire it is today.
The Emperor/Empress works on Janka II in the Imperial Palace.
