I understand that you are disgusted by this since the Zann Consortium is pretty much an OP criminal empire faction post-Battle of Hypori against the Cartel which happened 2 years before the Battle of Endor.
Zann Consortium overpowers Hutt Cartel after the Battle of Hypori which makes them the new bosses of the galactic underworld. That depends if the OP wants me to RP as the juggernaut Consortium. Galactic Civil War isn't just about the Rebel Alliance vs. the Empire though.
