Selok

Subcommander Selok was an officer in the Romulan fleet, who served the Romulan Star Empire as a spy. She entered the United Federation of Planets posing as a Vulcan Ambassador T'Pel. By 2367 she managed to establish a renowned name in her service.

When her espionage service was concluded, the Romulans arranged her accidental "death" while being transported from USS Enterprise (NCC-1701-D) to the warbird so that she could return to the Romulan fleet.
