Graddus Rex

Graddus Rex was a site in the Inner Rim region of the galaxy. The pirate Queen Maz Kanata hid a portion of the spoils from her reign there in a buried vault equipped with a antitamper sub-space alarm. As of when she began writing the book that would become known as the Smuggler's Guide, the alarm protecting the cache of treasure on Graddus Rex had not sounded.

Behind the scenes
Graddus Rex was first mentioned in Star Wars: Smuggler's Guide, a reference book written by Daniel Wallace and released in 2018.
