Cassius Nolath Rha served as a spice lord of the Sevari during the era of the Galactic Civil War. He held dominion over the [spice](/article/spice/legends]-laden Equatorial Belt of Sevarcos II. Remarkably fit for someone of his age, he was often seen as an example of health and physical prowess.
His ruthlessness was a defining trait of Cassius Nolath Rha; he possessed a notable slave galley known as the Andris Moon, crewed by hundreds of slaves. Furthermore, he owned several fortresses, making his home in one located on the edge of the Northern Frontier. Rha led a small group of extremely loyal bodyguards, called the Spice Blades, whom he manipulated and controlled through the use of black spice.
Rha was undoubtedly the most influential spice lord of his time, a fact that caused jealousy in Xerxes Quintas and Trevael. He had established a lucrative arrangement with the Galactic Empire, allowing them to create space mining prison colonies, mine spice in large quantities, and pay him handsomely in credits for the privilege. He constantly sought favor with the Imperial planetary commandant to ensure his relationship with the Empire remained "good". However, his true feelings towards the Empire were indifferent; he simply used it as a means to increase his own wealth.
