The year is 2422 ATC (After Treaty of Coruscant, out of game 1231 BBY). Nearly two decades of war led by Dark Lord Belia Darzu, the Sith master of Technobeasts, have devastated the Jedi-controlled Republic.
The galaxy is in a state of chaos following the collapse of the HoloNet and interstellar commerce that began centuries prior. An outbreak of Candorian plague, known for wiping out billions in days, killed two-thirds of the inhabitants of some Republic worlds. This chaos forced Jedi into greater leadership positions, even commanding the Republic military. Currently under the rule of a Supreme Chancellor who is also a Jedi Master, this position has been held exclusively by Jedi for two centuries.
