Sopek

Ch'uiv was a Romulan male alive in the 22nd century.

In the 22nd century, Ch'uiv infiltrated the Vulcan High Command under the alias of Sopek. As Sopek, Ch'uiv assumed command of the Vulcan starship Ni'Var. As Captain of the Ni'Var Sopek was sent to Coridan to bring Subcommander T'Pol back to Vulcan following the destruction of the P'Jem monastery. (ENT episode Shadows of P'Jem)

Ch'uiv later returned to Romulan space and assumed leadership of the Ejohi Ormiin dissidents. His group kidnapped the Romulan scientest Ehrehin - who had been working on a warp seven drive for the Romulan Empire. Ch'uiv murdered the Section 31 agent Tinh Hoc Phuong. Fellow operative Charles Tucker III and the Romulan Ehrehin escaped from Ch'uiv's grasp - with Ehrehin returning to Romulus, and Tucker returning to Earth. (ENT novel The Good That Men Do).
