    N-K Necrosis was a highly advanced combat droid created from the body of the late General Grievous of the Confederacy of Independent Systems during the First Galactic Civil War. Doctor Nycolai Kinesworthy, a cybernetic scientist, was hired by the Galactic Empire to create the Necrosis droid. Dubbing the project "N-K," Kinesworthy established a shop in the Myyydril Caverns on the planet Kashyyyk to begin work on the droid. He eventually hired the scientist Treun Lorn to help advance the project. After Lorn hired the assassin droid IG-72 to retrieve a pair of outdated IG-100 MagnaGuards to serve as N-K's bodyguards, the dark side Prophetess Merili led the two scientists to one of Emperor Palpatine's secret storehouses on Utapau, where she provided them with the mechanical body of the cyborg Grievous.

    After placing an advanced Droid Brain in the mechanical body, Kinesworthy dubbed the completed project "N-K Necrosis," and renamed the aging MagnaGuards "NK-3." The NK-3s instructed Necrosis on how to fight with a lightsaber, with Necrosis wielding a Double-Bladed Lightsaber that contained the Bane's Heart crystal. At some point around the Battle of Yavin, Lorn stole Necrosis and his NK-3 bodyguards to use them for his own purposes. In 1.5 ABY, a group of spacers investigated the lower regions of the Myyydril Caverns at the behest of Kinesworthy. During their investigations, the group inadvertently aided Lorn in activating Necrosis. They then defeated both N-K Necrosis and his bodyguards before taking whatever they deemed valuable.
