The Ore-duke Baron Rubix controlled a delving citadel on the planet Shu-Torun. During the War on Shu-Torun, in which Rubix and the other ore-barons rebelled against the Imperial-backed Queen Trios, Rubix sent his vessel the Lava Leviathan to kill Trios in the ancestral retreat of the Shu-Torun royalty, a site considered sacred and peaceful. The attack was unsuccessful and the leviathan destroyed, causing Trios to request that her Imperial allies destroy Rubix's citadel as punishment for his blasphemy.
Rubix' delving citadel was first mentioned in the comic book Darth Vader (2015) 17, which was written by Kieron Gillen and released in 2015.
