The Dwartii comprised a societal group residing within the galaxy. Snoke, the Supreme Leader commanding the First Order, possessed a ring adorned with gold etchings displaying the Dwartii's glyphs. Additionally, they lent their designation to the planet known as Dwartii.
The initial reference to the Dwartii appeared in the reference work titled Star Wars: The Last Jedi: The Visual Dictionary, penned by Pablo Hidalgo and released on December 17, 2017. In response to an inquiry on Twitter, Matt Martin from the Lucasfilm Story Group expressed his belief that the book's reference to "the Dwartii" was actually alluding to the Four Sages of Dwartii.
