A harsh and unforgiving world, Korriban has been the seat of power for many Dark Lords of The Sith over many centuries. Six thousand years before the outbreak of the Galactic Civil war Jedi exiled from the order and adrift in space found themselves upon Korriban and due to the nature of there abilities were elevated to the level of Gods to the indigenous people and soon this worship was warped into subservience to a tyrannical new rule by the Dark Jedi who came to adopt the name ‘Sith’ as a title. After a thousand years of fortification and uninterrupted rule by a Republic oblivious to there existence, hyperspace explorers Gav and Jori Daragon unwitting discovered safe passage to Korriban and The Sith and in doing so ignited the Great Hyperspace War.
With the Sith Lord Naga Sadow leading and ultimately loosing the first Great Hyperspace War many other Dark Lords would follow in his wake most notably Exar Kun & Ulic Qel-Droma, Even Darth Revan and Malak visited Korriban to unlock its dark secrets during the Jedi Civil war. Korriban has continued to serve as both a refuge and battle ground for both Sith and Jedi over the continuing centuries, Darth Bane sought council from the Holocrons of long dead Sith Lords in aid of gathering information in the formation of his order the Rule of Two, even Palpatine was known to journey to Korriban to converse with the dead, council that would be again searched for by future Dark Lord Darth Krayt would reestablish Korriban as the homeworld of a Sith Empire once more, over a hundred years after the fall of the Empire.
