Romulan

The Romulans are a secretive people who were originally part of the Vulcan race. Unlike their Vulcan cousins, the Romulans remained a passionate people with an absolute certainty of right and wrong, who is a friend and who is an enemy.

Romulans are not as violent as many Federation enemies such as the Jem'Hadar and frequently try to learn more about their enemies before making the first move in a hostile situation. The Romulans aren't as openly aggressive as the Klingons or as passive as the Vulcans, instead attempting to keep themselves and their technology hidden from their enemies.
