Korriban

Korriban was the ancient homeworld of the Sith Order and the native homeworld of the Sith race. The desert world is also known for its tombs and the Valley of the Dark Lords.

Prehistory
Although there are little records about what occurred before 30,000 BBY, but records say Sith civilisation started around 100,000 BBY on Korriban.

Pre-Republic
Long before the dawn of the Old Republic, the Kiliks in 30,000 BBY had made a colony on Korriban lead by a Kilik Sith lord. Eventually the Kiliks were driven off the planet

Around 27,700 BBY, the Rakatan Infinite Empire invaded Korriban, but yet were driven off by the Sith under the rule of King Adas who would eventually die in this battle.

After the Rakatan invasion, the Sith would hijack Rakatan technology and make their own mini-empire at this point, but Sith society crumbled after Adas' death, relocating to neighbouring worlds such as Ziost, Tund and Arbra.

Eventually Xim the Despot would conquer Korriban around 25,100 BBY and would be given the name of Pesegam until the Empire of Xim fell. Korriban would remain a desolate graveyard for the next thousands of years to come.

Old Sith Empire
After the Hundred-year Darkness thousands of Dark Jedi who were exiled from the Jedi Order were defeated and relocated to Korriban. These Dark Jedi would eventually create the Sith Order along with the Sith Empire.

For many generations to come, Dark Lords of the Sith would rule the Sith Empire and Korriban would be its capital. Some notable Dark lords of this time were Ajunta Pall, Tulak Hord, Marka Ragnos, Naga Sadow, Revan and Vitiate.

Multiple Sith lords have put themselves in stasis on Korriban during this time. Examples of these Sith are Tazrel Jurna and Darth Kaal.

According to Reborn Sith records, there was a Sith Empire under the rule of Darth Madreus from 3910-3711 BBY. This empire would be dominant in the Unknown Regions and Sith Space. Eventually this empire would eventually collapse. The cause is unknown.

Eventually the New Sith Empire arose in 2000 BBY and Korriban would remain the capital until the fall of the Old Sith Order in 1000 BBY.

Clone Wars and Galactic Empire
Korriban would remain an abandoned world by the Republic, Separatists and the Galactic Empire. The world would yet still be known for the dark side energy that fills the planet and its tombs untouched.
