General Gyero Minza was a top-ranking Tezwan military commander, having been installed into his position by Prime Minister Kinchawn upon his ascension to power. After Kinchawn opened fire upon and destroyed a Klingon Defense Force fleet using nadion-pulse cannons build on Tezwa, Kinchawn began to fear that his deputy Prime Minister Bilok, working in concert with Federation Presidential Chief of Staff Koll Azernal, sought to remove him from power by force. Kinchawn ordered Minza to seek out and kill any who would oppose his stance in these dangerous times. Minza obeyed and sent assassins to kill senior members of the Gatni Party, only partially succeeding in his mission.
