Nathema, originally known as Medriaas, was a fertile agriworld located in the Nathema system of the Outer Rim Territories' Chorlian sector during the time of the Sith Empire. The planet's Sith ruler, Lord Dramath, was deposed in 5103 BBY by his own illegitimate son Tenebrae at the age of ten, and the child received the title of Lord Vitiate and rulership of Medriaas from the reigning Dark Lord of the Sith, Marka Ragnos. Renaming the planet Nathema, Vitiate kept his world isolated from the power plays of his fellow Sith over the next century, and his isolation spared Nathema from the Great Hyperspace War in 5000 BBY.
