Soulsaber The Soulsaber was a dark side artifact that was created thousands of years before the Galactic Civil War . Description . The Soulsaber was a dark side weapon that was similar in design to a lightsaber . The Soulsaber ' s forty - five centimeter - long hilt consisted of a deep black cylindrical rod wrapped in a bronze - like metal that was formed into the shape of a dragon . When the weapon was activated , a one - and - a - half meter - long blade of energy was emitted from the open jaws of the dragon ' s mouth . The blade took on a deep violet hue and consisted of an obsidian - colored core with blood - red flecks flashing up and down the blade ' s length . More of a manifestation of the dark side of the Force itself than simply a weapon of the dark side , the Soulsaber was an abomination to the light side and all life . It was a nexus of dark side energy and its presence could be felt by anyone standing within ten meters of it . Non - Force - sensitive beings felt very uneasy in its presence , while Force - sensitive beings experienced great discomfort in the form of headaches or nausea , finding it difficult to concentrate on a particular task , and were aware that they were near a major source of dark side energy . Any being untainted by the dark side who touched the Soulsaber was immediately hit with a backlash of dark side energy . The Soulsaber was created not only to destroy life , but to corrupt Force - sensitive beings to the dark side . Simply igniting the weapon filled the wielder with negative emotions , such as anger , aggression , and fear , and the wielder heard a dark whisper of great power inside their head . This alone could turn some beings to the dark side and had the potential to create infighting among a group of darksider s who each wished to possess the weapon . While the Soulsaber ' s energy blade acted much like a lightsaber ' s , any being struck by it felt a stab of unbelievable and agonizing cold , and were flooded with emotions intended to push them over the brink to the dark side . The wielder , too , was pushed further to the dark side each time they struck an opponent . In combat , the Soulsaber provided its wielder with the Force ability Battlemind , allowing them greater prowess in battle through enhanced concentration and commitment . The wielder ' s stamina was augmented so that they could continue fighting even at the brink of death , but at the price of never knowing how close they were to dying at any point . The Soulsaber could also siphon Force energy from any being it struck and temporarily channel it to the wielder ; energy could also be drawn from the wielder ' s surroundings . History . The Soulsaber was built by a Dark Jedi , and he used it in a bloody battle on Pamorjal against the Jedi Order , in which many Jedi Masters died . However , the Dark Jedi was ultimately defeated and the Jedi concealed the Soulsaber in a remote system , protecting it with the light side of the Force in the Cavern of Light on the planet ZXK - 100346 . 6a . The Dark Jedi Thaum Rystra later went and stole the artifact with the unwilling assistance of Caeleb , who enabled Rystra to bypass the light side protection .
