Darth Tenebrous

"To we who dwell in the Force, normal life is little more than pretense. Our only actions of significance are those we undertake in service to the dark side."

- Darth Tenebrous, to Darth Plagueis, on his views of the Force

Rugess Nome&mdash;known only to his apprentice as Darth Tenebrous&mdash;was a Dark Lord of the Sith of the lineage of Darth Bane&mdash;a Bith male possessed of a calculating intellect, Nome was a legendary starship designer known across the galaxy and, as a Sith Lord, was obsessed with shaping the future. As Darth Tenebrous, he was the master of Darth Plagueis.

Seeking out an apprentice
Rugess Nome was widely known for legendary starship design throughout the galaxy. However, he was secretly a Sith Lord&mdash;named Darth Tenebrous&mdash;who was seeking an apprentice.

In searching for a new Sith apprentice, Nome manipulated a middle ranking InterGalactic Bank agent named Caar Damask into meeting his future wife, knowing that if they had a child, their offspring would be strong in the Force.

When the expected child, Hego Damask, turned five, Nome traveled to Mygeeto and convinced his parents to hand him over. Nome took the child as his apprentice, naming him Darth Plagueis.

Demise
"For the last time I call you apprentice and I applaud your skillful use of surprise and misdirection. Perhaps I was wrong to think you had no stomach for it."

- Rugess Nome to his Sith apprentice, Darth Plagueis

At some point, Tenebrous and his apprentice, Plagueis, traveled to the planet Bal'demnic; there, Plagueis set in motion his plan to kill his Master. When he realized that his apprentice's desire to kill him had seriously endangered the continuation of the Sith, Tenebrous expressed disappointment in his pupil, and ended up stranding the Muun where he required an enviro-suit to survive. Plagueis, angered by this, broke the Bith's neck. As the unconscious Tenebrous slowly died, Plagueis utilized the Force to study microscopic changes in the Bith's body, observing the slow death of his neurons and midi-chlorians.

However, this was not the end of Tenebrous, who ensured the survival of his own consciousness into altered midi-chlorians&mdash;which he labeled maxi-chlorians. Those maxi-chlorians would then migrate not into the Force, but into Plagueis, the "diseased one". Not possessing a Bith's precision, Plagueis would never suspect Tenebrous's consciousness was inside his body, infecting cells with maxi-chlorians that would cut off the host of its Force-sensitivity. In order to fulfill his goals, Tenebrous sacrificed his ability to sense the motion of the future, something he no longer required since he already knew his future.

As his body died, Tenebrous entered his apprentice's body and slipped into his cells. As the retrovirus propagated, the Bith gained access to Plagueis' powers of foresight. At that moment, he discovered and felt Plagueis' own death at the hands of his apprentice, which was only visible as a smear of darkness. That vision horrified him; Plagueis would die too soon, and Tenebrous would not fulfill his ultimate goal&mdash;seizing and becoming the Chosen One when he would appear.

Seeking an answer to understand Plagueis' complacent behavior, Tenebrous threw again his mind at the future, but could see nothing, as the retrovirus infected Plagueis' every cell; his apprentice was now robbed of his foresight power. Wholly giving himself to panic, Tenebrous escaped Plagueis' body to think about a way out, only to discover his mummified remains. Time had passed, but the Sith Lord was unaware of it. He then wondered if his foresight, instead of being eliminated, had been twisted in upon itself, forcing him to endlessly relive his death. At that moment of realization, the Dark Lord wished he still had a mouth with which to scream.

Behind the scenes
Rugess Nome's Sith name, Darth Tenebrous, was included in a 2006 blog entry by Leland Chee, the keeper of the Holocron continuity database, marking the character's first mention in Star Wars canon. Chee stated that Tenebrous's name may have been derived from the word "tenebrous," a word meaning dark, gloomy, or obscure. In 2008, author James Luceno indicated that if he were able to, he would choose "Darth Tenebrous" as the name of the first Sith to ever use the Darth title. Tenebrous appeared in Luceno's 2012 novel, Star Wars: Darth Plagueis, as the Master of Darth Plagueis.

When deciding Nome's species, Luceno was seeking an existing intelligent and "brainy" species in Star Wars canon. The Bith species fit the bill, but Luceno found that he associated Bith with harmless jizz-playing bands rather than menacing Sith Lords. However, cognizant of the fact that many different personality types could be found in a single species, he ultimately said "what the heck."
