"Shinzon and his followers will be met with all deliberate force and sent back to that black rock they came from."
Remus was the inhabited third planet of the Romulan system, which was located in Sector Z-6 of the Alpha Quadrant. It was tidally locked to its parent star and the homeworld of the Remans, a humanoid species subject to the Romulans.
The location of Remus in the Milky Way Galaxy was depicted on a Federation star chart in 2293. (TOS: "Balance of Terror", display graphic; DS9: "The Search, Part II"; Star Trek VI: The Undiscovered Country, production art; Star Trek Nemesis)
Political and historical
Remus and Romulus were the major worlds of the Romulan Star Empire, one of the great powers in the Alpha Quadrant. Remus was an important dilithium source and site of heavy weapons construction. Being forced to work in the dilithium mines, the Remans were regarded as an undesired caste in Romulan society but also had the reputation of being formidable warriors. In 2379, Shinzon, a Human clone imprisoned on Remus, became Praetor of the Romulan Star Empire by a coup d'état involving the murder of almost the entire Romulan Senate. However, Shinzon's subsequent plans to annihilate Earth were thwarted by the Starfleet Captain Jean-Luc Picard.
In Roman mythology, Romulus and his brother Remus were known as the brothers who founded the city of Rome. Romulus became the first king after killing his brother. The relation between the planets of Romulus and Remus reflect this. See Romulus and Remus. This would indicate that Romulus and Remus, along with Romulan, Reman, were names drawn from Earth mythology, not their own terms, which makes sense because the Romulan/Reman languages are different. There is ample precedent, as many peoples on Earth call themselves by different names than those which others use for them.
When it came time for scriptwriter John Logan to pitch his idea for a Star Trek film (which ultimately became Star Trek Nemesis) to Rick Berman, Logan initially spoke about revealing more of Remus than had been seen up to that point. Logan was inspired by the fact that the planet had never been fully shown on-screen before and that very little information had been established about it. Though Berman was at first baffled as to what Remus was, the idea of actually depicting the planet eventually won his approval. "He loved that idea, once he knew what it was," Logan recalled, laughing. "So I'm really proud that I was able to go into the Trek mythology and add a part about what the Romulan Empire is." (Star Trek Monthly issue 99, p. 31)
In "The Aenar", the two Romulan drone-ships are seen departing a planetary body without an atmosphere, with Romulus being visible in the background. It remains unclear whether the scene was supposed to show Remus or merely another asteroid or moon.
According to Star Trek: Star Charts (pgs. 55, 66), Remus was a Q-class planet. The official name of the uniglobal government was the Reman Colonies. The dominant species were the humanoid Romulans and Remans. Remus was in or near the Romulan War Theater of Operations (2156-60).
In some Star Trek novels, Romulus was called ch'Rihan and Remus was ch'Havran. The Romulans are the Rihannsu, and Remus was said to be the more temperate of the two planets.
