Following Karagga's death, the ruthless Hutt Toborro seizes control of the Hutt Cartel and names himself Supreme Mogul, with Szajin as his enforcer. Sensing an opportunity in a weakened Republic, Toborro sets his sights on the planet Makeb — which holds enormous deposits of isotope-5, an extraordinarily rare mineral capable of warping gravitational and electromagnetic fields and generating immense energy from a single gram. Toborro buys off Makeb's mercenary defense force, the InterStellar Regulators, then begins mining isotope-5 from Makeb's core without any regard for the catastrophic damage the extraction will cause to the planet itself.
