darth nihilus, also known as the lord of hunger, is an antagonist in . alongside darth sion, he served as one of traya's apprentices, until ultimately betraying her and driving her into exile. nihilus imbued his dark soul into his mask and robes and had the power to drain the life force out of any living thing. following the betrayal of his master, nihilus used the might of the sith armada not to conquer planets, but to contain them so that he could "feed" off the force energy of each planet's lifeforms, wiping planets of life. however, nihilus was later drawn out and tricked into launching an attack on telos, believing it to contain the last jedi. the exile confronted nihilus on his ship, and nihilus was killed either after his former slave visas sacrificed herself due to their shared link in the force, or after his attempt to feast on the exile's connection to the force backfired and weakened him. despite his death, nihilus' soul would continue to live in his mask and robes for millennia to come, as well as inside his own sith holocron.
