This period, known as the subjugation, saw almost all of Talavaar united under a single banner of conquest.
In what should have been the empire’s finest hour, with victory within grasp, the Subjugator was betrayed by his wife, who took command of the Empire as it fled east before settling on the western banks of the Cut.
The Lady of Dusk
After betraying and murdering her husband, the Empress, most commonly known as “the Lady” ordered a retreat. Civil war broke out almost immediately, with those loyal to the Subjugator fighting against the Lady and her forces.
The Lady returned to The Black Tower in the Jewel Cities, and is slowly rebuilding her strength.
The military might of the Dusk Empire comes from the legion, an army of professional soldiers who swear an oath of loyalty to the Emperor (or Empress).
Much of the land of the empire is directly administered by governors, politicians who are responsible for raising taxes, ensuring continued operation of the imperial machine, and defending their regions.
Beneath governors are countless lesser administrators such as barons, mayors, and minor lords.
The cities under the Empire’s banner are ruled by Legates, members of the Legion who answer to the Lady directly, and often serve as her council.
Order within the cities of the Empire is maintained by local factions employed directly by the Legates, though Legionnaires may sometimes be deployed as peace keepers.
