Exar Kun. Darth Maul. Darth Tyranus... Those names strike fear into the hearts of every human being as they represent the most feared Dark Lords of the Sith in their time periods. All of them are renown for their mastery of the Force and their ruthlessness. What is common among them is that every single one was an extraordinary warrior. It didn't matter whether they preferred the dual-blades or a single lightsaber; they were the best fencers among the followers of the Dark Side. They reached perfection in merging their unbelievable skills in the Force with their talents of sword fighting, becoming the ultimate agents of the Dark Side of the Force itself. They were Obelisk.

The Order of the Obelisk concentrates on the purest form of the dark ways: Battle. Whereas the Sith simply let the Force guide them and the Krath use their skills to seek knowledge and occasionally summon the one or other undead Sith Lord, Obelisk are searching perfection through mastery of the lightsaber and battle Force. The Obelisk are possibly the best known Order since it is they who will go head to head with Jedi without hesitation, fighting battles planet side or in space docks, crossing crimson blades with azure and emerald ones wherever possible and reaching perfection in the Force by going down to the purest of all emotions: fear, anger, wrath, blood lust.

The Order of the Obelisk was led by the Obelisk High Commander and was created on 9th October 1997 by the then OHC Razor.
