Sith

The Sith were an ancient order of Force worshipers who followed the dark side of the Force and fought wars against the Jedi during the era of the Old Republic. Marshaling battle stations capable of destroying planets, Sith sought to transcend mortality, and some, such as Darth Bane, lived on as malevolent spirits on the Sith homeworld of Moraband.

Philosophy
The Sith worshiped the Force as the Jedi did, although they focused on its dark side, and dwelt on immortality.

Ancient wars
"A battle station that could be an ultimate weapon, as bad as anything used by Bane or Revan or the other ancient Sith, back in the wars of the Old Republic."

- Leia Organa to Leto Borian on the Death Star

An ancient group, the Sith of Moraband originated from the first order of Force-adepts who separated into two distinct groups after the Hundred-Year Darkness, the other being the Jedi, also an order whose members worshiped the Force. According to Jedi Knights of the Old Republic, the earlier first order of Force worshipers which predated both groups possibly originated on Rakata Prime, but its civilization ultimately turned upon itself. The Sith kept tomes on Moraband, and their myths told of the legendary Dark World said to be a physical source of the dark side of the Force in the Unknown Regions.

The Sith fought against the Jedi in the wars of the Old Republic, when Darth Bane, Revan, and other ancient Sith utilized battle stations as ultimate weapons capable of destroying entire planets. According to some Jedi accounts, the Sith destroyed worlds to feed off the suffering of their populations through the Force, and some Sith supposedly attempted to transcend mortality using this method. A battle between Sith and Jedi was fought on Takodana, on the site that later housed Maz Kanata's castle. Many Jedi turned to the dark side and the way of the Sith, leading to reformers rising within the Jedi Council. Darth Bane reinvented his order when it was once thought eliminated, and his spirit continued to reside in the tomb of the dark side on the Sith homeworld of Moraband after his death.

Darth Plagueis taught his apprentice, Palpatine, the myth of the Dark World.

Maul was a Sith Lord who later formed the Shadow Collective as a viable third force during the period when the Galactic Republic and the Separatist Alliance were committed to the Outer Rim Sieges.

During the era of the Galactic Empire, conspiracy theories suggested Count Dooku had been recruited from Moraband as an obsessed student of the ancient Sith. The Empire constructed the Death Star, a battle station considered as destructive as those used by Bane, Revan, and other Sith in the wars against the Jedi.

While searching for a true answer to the ways of the Force after the massacre of his Jedi, Luke Skywalker uncovered Sith myths concerning the Dark World, and encountered the spirit of Darth Bane on Moraband. The ancient Sith Lord attempted to exert his malevolent influence on Luke by speaking to him in his own voice, but the Jedi was not swayed by Bane's crude ploy.
