Korriban (LDR)

"Korriban shall be as it always was. A graveyard for the darkest of the Sith Lords, still whispering within their tombs. It shall always be a source of evil, spawning threats throughout the millennia. It, like Malachor, brushes the edges of the empire that waits in the dark. And like Malachor, the Sith have forgotten it...for a time. They will remember."

- Darth Traya

Korriban was a Sith planet that housed many evils. It was known as the birthplace of the Sith and the graveyard of the Sith, as it housed many ancient tombs and temples.

Adas's Sith Empire
King Adas, the first King of the Sith, created an empire that fought the Infinite Empire when they invaded Korriban. While Adas knew they could not win the war through martial might, he appointed Akirakon Sin as the leader of the Brotherhood of Shadow. The Brotherhood of Shadow waged a silent war with the Infinite Empire by killing the key figures in the empire. Then the Infinite Empire collapsed upon itself without a strong tactical prowess. With the Infinite Empire weakened, King Adas led warriors on the battlefield, and died when doing so. With the Infinite Empire defeated, Adas said for Akirakon Sin to rule his empire, shortly before dying. His loyal advisors betrayed Akirakon Sin, and sent him and his Brotherhood of Shadow to eternity within the Infinite Empire's artifact. His advisors formed a Council of Lords, no longer being ruled from king to king.
