Naga Sadow was an ancient Sith Lord who, according to the quasi-historical Qel-Droma Epics, led the Sith Empire during the Great Hyperspace War against Empress Teta and the Jedi Order while also triggering the Cron Supernova. The Massassi of Yavin 4 allegedly built the Great Temple under Sadow’s leadership in circa 5000 BBY in his honor, despite his treatment of the Massassi being poor.

A likeness of Sadow was chiseled into the rock walls of the Sith Citadel on the Sith planet Exegol, and First Order Supreme Leader Kylo Ren heard Sadow’s voice among the unintelligible whispers of several Sith Lords while confronting the Dark Lord of the Sith Darth Sidious on Exegol in 35 ABY.

Naga Sadow was first mentioned in the new Star Warscanon in the twenty-third issue of the De Agostini magazine Star Wars: Build the Millennium Falcon, published around June 10, 2015. The character Naga Sadow originally appeared in the Star Wars Legends continuity in the first issue of the comic seriesStar Wars: Tales of the Jedi – Dark Lords of the Sith, written by Tom Veitch and Kevin J. Anderson and released on October 4, 1994.
