Darth Nihilus 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.  Experiencing the shadow that obliterated almost everything on and around the planet made Nihilus crave Force energy. The affliction painfully ravaged his body while rendering him a wound in the Force.  over time, became one of three concurrent Dark Lords of the Sith.
