Third Sith Civil War (Line of False Time)

Background and prelude
From 874 ATC, when Independent Confederacy and Sith Empire signed "Uniting Treaty" and united in to Galactic Sith Empire, until 1830 ATC, most of galaxy flourished under imperial government. For nearly thousand years imperial government was able to fully satisfy needs of their people, enstrenghting position of Imperial military and civilian government in society, colonize thousands planets and building great and prosperous empire.

As years passed, every new Sith Emperor had less significant and less powerful position. Power was transfered to Council of Ministers, Imperial Parliament (Imperial Merit Council and Imperial Chamber of Deputies) and after few hundred years, Galactic Sith Empire lost its former magocratic core and became meritocratic, military and oligarchic empire, where power was divided between people, representanting meritocracy, army and navy representanting martial traditions of empire and corporations, merchants and trade guilds representanting oligarchy.

Since rule of emperor Solyr IV. (1650 ATC), when was Sith Imperial Constitution changed for fourth time and again in favor of secular government, small groups of radical conservative Siths, especially formed from Sith Academies leadership and Dark Temple of Dromund Kaas, created so-called "Shadow Council" as successor of disbanded "Dark Council". Shadow Council decided to start building large conspiracy among Sith Empire to influence military, oligarchy and people in to restoring Sith Order power and magocratic rule. They gathered their allies and supporters to build strong army and prepared Sith masters, acolytes and lords for final clash with Imperialists.

Numbering conflict as "Third" civil war was based on First Civil War, which was small-scale conflict on Dromund Kaas after Vitiate death and Second Civil War after Battle of Nar Shaddaa.

Sith terrorism
First phase of Sith uprising was series of rebellions and terrorist attacks initiated by Sith lords on Coruscant, Alderaan and Dromund Kaas.
