- "Strength, power and strategy marked the rule of Marka Ragnos. Descended from the original Sith inhabitants of Korriban and the Dark Jedi exiles who interbred with them, Marka Ragnos was destined for greatness. He conquered his competitors in a series of quick, ruthless campaigns and became Dark Lord of all Sith, a title he would hold for more than a century. The reign of Marka Ragnos might have been short-lived had he not displayed great strategic discipline. Instead of clashing directly with Sith challengers who hungered for his power, he pitted his enemies against each other to weaken and destroy them. Similarly, he was one of few Sith of his era who knew of the existence of the Republic and the Jedi Order. He chose not to attack, and instead focused on strengthening the Sith Empire. The golden age of the Sith would end shortly after his death, but the legacy and spirit of Marka Ragnos would live on within his tomb in the Valley of the Dark Lords."
- ―In-game Codex (Locations)
The Tomb of Marka Ragnos was the final resting place of the Dark Lord of the Sith Marka Ragnos. Ragnos ordered his tomb built in the Valley of the Dark Lords, which was lost to record for centuries before Sith archaeologists under Darth Malak excavated it.
Ragnos was buried with his gauntlets, which had the dark power of giving the wearer specialization with the lightsaber.
