For other uses, see sentinel.

A Sentinel was a civilian officer within Romulan society who were members of the Royal Civil Attaché and wore the Imperial Court uniform.

They served as the personal protectors and assistants to the Emperor and Empress. They were roughly the equivalent of a Centurion, however, did not possess a military ranking structure as the Romulan people long ago realized the problems that could arise from such a system.

Iavo held the title of Sentinel. (TNG novel: Red Sector)
