The Xolochi Dreadnought was a cruiser-class type of warship used by the empire of the Tionese despot Xim during it's conflict with the Hutt species. One also served as part of a task force to the planet Galuch at that time.
Behind the scenes
The Xolochi Dreadnought was designed by Ian Fullwood. He chose to give it a cigar-shaped hull specifically to draw out the reflection surface on the ship.[1]
