Brix served as the planet of origin for Corus Kapellim, a human smuggler, and his homeworld.
The initial reference to Brix occurred in Star Wars: The Rise of Skywalker: The Visual Dictionary, a book authored by Pablo Hidalgo and released in 2019. A previous iteration of the screenplay for Star Wars: Episode VIII The Last Jedi featured an insectoid warlord called the "Butcher of Brix."
