Shevatus (in Howard's story named Shevatas) was a master-thief from Zamora who sought to steal treasure of Thugra Kotan's Ivory Dome in Kuthchemes. He successfully negotiated several obstacles, but met his end in the central treasure chamber.

"...wiry and lithe, as became a master-thief of Zamora. His small round head was shaven, his only garment a loin-cloth of scarlet silk. Like all his race, he was very dark, his narrow vulture-like face set off by his keen black eyes. His long, slender and tapering fingers were quick and nervous as the wings of a moth. From a gold-scaled girdle hung a short, narrow, jewel-hilted sword in a sheath of ornamented leather. Shevatas handled the weapon with apparently exaggerated care..."
