San'Shyuum (Earth-2042)

"I don't think I like them. Too charming. Slippery."

- Han Solo

San'Shyuum are a near-extinct sentient species of humanoids native to Janjur Qom. Prior to the Great Schism in 20 BBY, the San'Shyuum served as the leadership caste of the Covenant and as a result, the Confederacy of Independent Systems. By that time, the San'Shyuum had exerted complete control over the Covenant's religious and political affairs.
