Star Wars: The Old Republic: Revan
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 5,103 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 5,000
BBY. The following year, Vitiate summoned the eight thousand
remaining Sith Lords to Nathema in order to save the crumbling Sith
Empire, but the powerful Vitiate dominated their minds instead and
proceeded to use their strength in a complex ritual of Sith magic
that granted him immortality while stripping the Force from the
entire planet.
Every
living thing on Nathema was instantly killed by the Ritual of
Nathema, and the planet became a barren wasteland devoid even of
droids and technology as Vitiate, now known as the Sith Emperor, hid
his past and the hyperspace routes to Nathema from his newly
reconstituted Empire. Nathema's rediscovery and the revelation of
what he had done to the world sparked a plot among the members of the
Empire's ruling Dark Council to unseat their Emperor and prevent him
from repeating the ritual, but the destruction of the conspiracy once
again erased knowledge of Nathema from the mind of the Empire.
