Sith Lord of the Triumvirate
Darth Nihilus (pronounced /ˈnaɪ.i-lɪʒ/) was a Human male who reigned as a Dark Lord of the Sith during the era of strife following the Jedi Civil War. Before becoming a Sith Lord, he lost everything during the Galactic Republic’s war against the Mandalorian Neo-Crusaders. He survived the activation of the Mass Shadow Generator superweapon during the war’s final battle at the planet of Malachor V, which surrounded the planet with a destructive spacial phenomenon known as a mass shadow that obliterated almost everything and everyone on and around the planet. Experiencing the shadow made Nihilus “hunger” for Force energy, and the affliction began to ravage his body. In his pain he became a wound in the Force and was found by a seeker of such things, the Sith Lord Darth Traya, who told him that she could teach him to feed his endless hunger. He accepted her offer of apprenticeship at the Trayus Academy on Malachor V, and, over time, he became one of three concurrent Dark Lords of the Sith.
Together, the three formed a triumvirate with Traya at its head and her other apprentice, Darth Sion, as the third member. The trio chose individual names for themselves, with Darth Nihilus becoming the Lord of Hunger. The apprentices grew in strength during their training and eventually overpowered their Master. Sion defeated Traya, while Nihilus sapped her energy, before the two Sith exiled her and combined their powers to sever her ties to the Force. Nihilus’s affliction developed to the point where the Dark Lord was forced to call upon the dark side of the Force to encase his spirit within his mask and armor to stay alive. Sion and he then began a Jedi purge, causing the virtual extinction of the Jedi Order. Nihilus was responsible for the devastation of the planet Katarr, killing and absorbing the Force energy of the Jedi at the Conclave on Katarr, along with every other living thing on the world save one Miraluka woman named Visas Marr, whom he would take from the surface and make his Shadow Hand.
