The "True Sith" was an obscure and largely unknown order of adherents to the dark side of the Force.
- "You thought that the corrupted remnants of the Republic, the machines spawned by technology that Revan led into battle were the Sith? You are wrong. The Sith is a belief. And its empire, the true Sith Empire, rules elsewhere. And Revan knew the true war is not against the Republic. It waits for us, beyond the Outer Rim. And he has gone to fight it, in his own way."
- ―Kreia, to the Jedi Exile
After the conclusion of the Great Hyperspace War and the dissolution of the Sith Empire, one Sith Lord managed to escape and hide in the Unknown Regions along with his most trusted Dark Lords. Using dark rituals, the Emperor prolonged his life and his undisputed rule.
In 3,951 BBY, Kreia told the Jedi Exile that this mysterious order had been in existence for tens of thousands of years and were silently waiting in the Unknown Regions during the time of the Jedi Civil War, and that they were the ones the encouraged Mandalore the Ultimate to attack the Republic.
According to Kreia, the "True Sith" had existed for millennia prior to the rise of the modern Sith Empire. Kreia stated that both Malachor V and the graveyard planet, Korriban, had once been planets at the edges of that mysterious Empire, and that while these "True Sith" had forgotten those ancient worlds of the dark side, they would remember.
Following the Jedi Civil War, Revan vanished from known space, supposedly to search for and destroy this order. Later, the Jedi Exile would also leave known space to fight alongside Revan.
Almost two hundred years later, the True Sith returned. Under the leadership of the Sith Emperor and his Dark Council, they invaded the Republic and started the Great War. After almost a century of fighting, the war ended with the signing of the Treaty of Coruscant, which was signed after the Sith sacked the capital. The Republic was forced to give up many systems to the Sith and a Cold War began between the Republic and the re-established Sith Empire.
Behind the scenes
The existence of the "True Sith" has caused some confusion with their placement in the canonical timeline of galactic chronology. When the game was first released, the establishment of the Old Sith Empire was believed to have taken place circa 25,000 BBY. Additionally, the beginning of the True Sith's existence was fixed as being approximately "tens of thousands of years" in the past. In 2005, however, the establishment of the Old Sith Empire was retconned to have happened around 6,900 BBY, which presented a new divide in the historical placement of the two groups, and indeed in the very nature of the Sith themselves.
It has since been mentioned by VIPs on developer Obsidian Entertainment's message boards that the company in fact did not use the "25,000 BBY" date as a basis for their development of the True Sith; the order was conceived as an entirely separate geographic group from the later Sith Order of Marka Ragnos and its like.[source?]
Later, it was discovered that, after the Sith King Adas died while driving the Rakata from Korriban in 27,700 BBY, the Sith species possessed the technology to relocate themselves to nearby planets, creating the region known as Sith Space and the earliest Sith Empire. It is therefore possible that some Sith from this era became the "True Sith," taking up residence out in the Unknown Regions, and eventually constructing the Trayus Academy on Malachor V.
