Eisn (also known as Ket-cheleb or Stelam Rom'lnz or 128 Trianguli) was a spectral class G9 white star, primary of the Romulan system. The Federation name for the star was Romulus. (TNG video game: Echoes From the Past)
This area contained the home planets of the Romulan Star Empire, Romulus and Remus, as well as the moons Pirek and Elvreng. The system had a secondary star which is known as Romulus B. (TOS - Rihannsu novels: My Enemy, My Ally, The Romulan Way)
During the final battle of the Romulan Civil War in 2276, the crews of the USS Enterprise and ChR Bloodwing created a link between Eisn and Sol to defeat an attempt by the Three to destroy the Sol system with a sunkiller bomb. Ael t'Rllaillieu said in a public address that this event permanently bound the two stars together and any future attempts on either star would likewise affect the other, though she was bluffing. (TOS - Rihannsu novel: The Empty Chair)
In 2387, Eisn was destroyed with the rest of the system in the shockwave caused by the Hobus supernova. (ST comic: "Countdown"; TOS movie, novelization & comic adaptation: Star Trek; STO website : The Path to 2409)
System
There were at least seven planets in the system:
- Stelam Rom'lnz I: Aranusia
- Stelam Rom'lnz IIA: Rom'lasz (Romulus); class M, Romulan home world
- Stelam Rom'lnz IIB: Rav (Remus); class M, orbits Rom'lasz
- Stelam Rom'lnz III: S'latas
- Stelam Rom'lnz IV: D'lanam, literally "The Great Wonder"; a gas giant
- Stelam Rom'lnz V: Ulunam
- Stelam Rom'ln VI: Trijth (FASA RPG module: The Romulans (FASA))
- The Rihannsu novels state that the system contained six planets whilst FASA material indicates that there were seven but the latter only numbers six as Remus orbits Romulus.
