The Lava Leviathan was a vessel owned by the family of the Ore-duke Baron Rubix on the planet Shu-Torun. During the War on Shu-Torun, the baron sent it to attack the Ancestral retreat of the Shu-Torun royalty, in the hopes of killing Queen Trios, who served the Galactic Empire and was at the retreat with her allies planning their next move in the war. The vessel emerged from the magma surrounding the retreat and opened fire on the scared building, causing Trios to try and flee in a shuttle.
