The Javelin Dreadnaught, a warship, originated as a design of the Imperial Science Bureau during the Cold War. Darth Mekhis, then the leader of the Sphere of Technology, commissioned it. This vessel possessed a radiation-based superweapon, projected via its shields, with the capacity to eliminate all life within a three-kilometer zone. Following a successful weapon trial, it was gifted to Darth Marr.
In a clandestine discussion with an imperial officer under her command, Darth Mekhis privately named the vessel Ror'jhan, a title signifying "she-whose-leaves-sweat-poison".
