Remus

From FEInfobase

Remus is one of the worlds in the romulan star system.

Romulus apparently had no native species until a Vulcan group colonized it around 400 CE. These early Vulcans over time became evolved along the primitive savage ways of the old proto-vulcans and became the Romulans.At the same time a species called the Remans developed on Remus the twin world to romulus and was conquered by the Romulans later becoming a lower class in Romulan society.It is unknown if the remans are a type of mutated proto-vulcan or an entirely seperate native species to remus.
