- "The vessel. She belonged to Lord Rubix. I believe his should be the next delving-citadel to receive an Imperial education."
- ―Trios asks that the citadel be destroyed
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.
