Of all the races in the Star Trek universe, probably
the most misunderstood are the Rihannsu, called Romulans by the Federation.
Followers of Star Trek will recognize the Romulans as the implacable
enemies of the Federation, the perennial "bad guys". This guide will attempt
to provide readers with a Romulan viewpoint, a starting point from which
to understand Romulan culture, some information about individual Romulan
behavior, and the history behind Romulan conflicts with the Federation
and the Klingons.
