7000 years before the great Galactic Civil War the Jedi Knights had a disturbing war. Several hundred Jedi had been seduced to the dark side and wanted to use this power to rule the Galaxy.
The result was a massive war between the light side and dark side. The Light side won the war and exiled those remaining dark jedi to the outer rim. The Dark Jedi landed on a prehistoric planet of Korriban inhabited by Magical Creatures called the Sith.
The Sith were amazed with how the Jedi used their powers and proclaimed them gods. The Jedi became the Lords of the Sith and broke up into many clans.Each Dark Jedi was a Lord of is own Sith cult. Greed ruin each clan and the Jedi's used the Sith warriors against each other for control of the other clans. Then Lord Nylax united the clans and proclaimed himself 1st Dark Lord of the Sith.
The rest of the clans created a special Sith Lord council used to represent each others clans.After a DarkLord died the Sith Council would vote on who would be the new Dark Lord of the Sith.Centuries and millenia's would go by as Dark Jedi would breed with the Sith. This broke the Council into two cults the Pure Blood Sith and the Sith. The Dark Jedi and Sith creatures learned to mix the force and the Sith Magic into an Empire.
Lord Nylax is the first Dark Lord of the Sith.Through the centuries the The Galactic records have disappeared and information on Sith Lords 2nd-8th have vanished untill the 9th Lord of the Sith.We are searching old Jedi ruins to find the awnser so please be patient.
