Addicted to the spice ryll-which drove them into a murderous frenzy-the Porporite species had become a threat to the galaxy. The Neimoidians had a monopoly on ryll and, terrified of the coming Porporite swarm, turned to the Ganks to stop the Porporites quickly.
The Ganks were mysterious, cybernetic mercenaries that often worked for the Hutts. With the Ganks' reputation as cold-blooded killers, the Neimoidians were confident they could handle the Porporite armies. But the Ganks' solution was to eliminate the entire Porporites species, and they hunted the Porporites to extinction.
Encouraged by this “success,” the Ganks began wiping out other species, quickly becoming a far greater threat than the Porporites. The Jedi took up arms against them, but Supreme Chancellor Vocatara was forced to commission the first juggernaut droids to end the Gank menace for good.
