The Grand Sith Order was a military state government that existed from 5th Century ABY to 1830 ABY. It was successor to the Sith-Arzetian Empire and predecessor to the Grand Sith Empire. Darth Arkitekt, a former Jedi military tactician, founded it. The order's final Dark Lord was Darth Milos. Unlike previous Sith governments, except the Sith-Arzetian Empire, the Grand Sith Order was not driven by religion, but by simple hunger for power.
