Yes

As Imperious entered the Tomb of Ludo Kreesh, one of the most Historically Important Sith Lords of All Time, due to his intense Rivalry with Imperious Ancestor, Naga Sadow, following the peaceful passing of Another Ancestor, Marka Ragnos. Throughout the Ancient Empire There were Only a Handful of Sith Figures who, from Imperious Point of View Merited any Great Attention. Amongst them was The Last Sith King to Rise to power before Ajunta Pall and his fellow Dark Jedi Exiles landed On Korriban, this man was known as King Adas. Adas was important for one reason: He was the one he **** the Ancient Rakata off Korriban, and though it cost him his life, he was the one who wrested the Secrets of Holocron Creation from them for the Sith. And of Course Ajunta Pall was Important because he was one of the first to intermarry with the Original Sith Species.

Others were Marka Ragnos, Tulak Hord, Naga Sadow, Ludo Kreesh, Sorzus Syn, and a few others. And While Imperious Counted Naga Sadow, Ludo's Greatest and Most Hated Rival, amongst His Ancestors, he did have the Spirit of Horak-Mul, one of Kreesh's Last Loyalists following Sadow's Successful Ascension to Dark Lord of the Sith, Bound to him. As he Surveyed the Architecture of the Entrance he looked at Lord kirnon, and Nodded his consent. ''Alright Boys Start to Take Samples of the Nearby Pillars, and be sure to take Preliminary Recordings before taking the Samples. My Lord we will remain Here, You and Your Assassin should be able to allow us to Push further into the Tomb.'' Says Kirnon as Imperious nods and Then Signals for Darth Achelon and Half A Dozen Sith Acolytes to Follow Him and Khem Val.

Imperious then Went Further with Some Probe Droids for Mapping the Tomb.
