Necropolis, initially called Dahrtag, existed as a planet situated within the Core Worlds region of the galaxy. Positioned along the Giju Run, this world served as a vast burial ground, a tombworld where beings from across the Galactic Core were laid to rest. Furthermore, it provided a habitat for both boneworms and cryptberries.
Initially, the planetary body was known as Dahrtag. Yet, following the opening of this planet and its encompassing system to the wider reaches of the galaxy, the designation Necropolis emerged as a common term, employed by numerous travelers acknowledging the Necropolitans' deep respect for the deceased. Eventually, the initial designation, Dahrtag, faded into obscurity, surviving solely within military navigational charts.
General Grievous possibly engaged in combat with and eliminated a Dark Jedi at some point on this world. Additionally, it marked the location where Zak Arranda met his demise, only to be resurrected by Cornelius Evazan as an integral component of Borborygmus Gog's initiative, Project Starscream.
