Trihexalon Trihexalon , also called dragon ' s breath and hex for short , was a biological weapon of mass destruction . The Trade Federation ' s dragon ' s breath was formed from ore mined at Mount Merakan on Maramere , and refined and weaponized at a factory on Nod Kartha . Characteristics . Trihexalon was infamous in the Karthakk system as a deadly and highly dangerous weapon ; so much so that the Galactic Republic banned trihexalon because of its deadly potential . It was known to cause " complete biomass conversion " in victims , and could be refined to target individual beings or for use as a planetary bombardment weapon . In refined form , trihexalon was a dust - like substance that gave off a toxic , green glow , and became inert and stable at very low temperatures ; a major reason for the factory being on Nod Kartha . Small doses like the sample produced for Toth could be held in special vials , and would react upon release , causing an energy burst capable of instantly killing Humanoids . A single , palm - sized vial contained enough dragon ' s breath to kill three hundred Wookiees , though simply shattering the vial would only generate a blast of a few meters in size . Although unclear , it is implied that the aftermath of a Hex blast is horrific and gruesome ; Captain Cavik Toth immediately ordered droids to clean up the remains of Harro Ruuk and his subordinates after killing them with a sample vial they had just given him . History . Captain Cavik Toth of Sabaoth Squadron first tested it by launching missiles and sending bombers to destroy Point Modie on Maramere , which would have killed approximately one thousand civilians had Jedi Master Adi Gallia not intervened and destroyed the missiles launched before impact , with the help of the Lok Revenants . She decided the threat should be eliminated , teaming up with the space pirate Nym and his crew . They broke through the orbital defenses at Nod Kartha , the planet churning out Hex weapons . With precision flying and teamwork , they were able to stop the further production of such weapons . During the Battle of Geonosis , Toth brought a fleet of Hex Deployer s and Bombers to help the Confederacy of Independent Systems triumph over the Republic . Jedi Master Adi Gallia , her Padawan , Siri Tachi , Nym , and his Revenants plus a squadron of other Jedi , foiled Toth ' s evil ambitions by destroying his fleet of Hex weapons . Toth himself was killed in the battle . Sometime during the Clone Wars , a group of Padawans led by Mavra Zane and Chewbacca discovered a plot headed by Count Dooku and Shu Mai of the Commerce Guild to spread the deadly gas on Coruscant through the use of a " Subjugator " - class heavy cruiser that was modified for the distribution of the trihexalon . However , the plot was thwarted when Zane and Chewbacca , flying in the " Star Runner " , led the aforementioned group of Padawans into the " Subjugator " and destroyed the main reactor , subsequently destroying the battleship . In 41 ABY , Jaden Korr was led to a Thrawn - era Imperial research facility by a Force vision . There he found records requesting that the experiments in the facility be terminated by trihexalon gas protocol , indicating that knowledge of the gas either survived the Clone Wars , or a similar poison was later discovered by Imperial scientists .
