Romulus is the home of the Romulans, an offshoot race of the Vulcans. The planet was named after the mythical home of the Vulcan god Ket-cheleb known as Rom'laas. During the 4th century CE, a group of Vulcans left their homeworld Vulcan and settled the planets Calder II, Dessica II, Draken IV, Yadalla Prime and Barradas III. This civilization, called the Debrune, was regarded as a predecessor of the Romulan Star Empire. After their odyssey, which lasted for centuries, they finally reached Romulus, a planet that matched all their needs and seemed as a perfect place to begin a new civilization.
