Jazen was a male human who lived during the Cold War. During the Republic's initiative to resettle the planet Taris, Jazen served in the Republic Army, held the rank of major, and was stationed on Taris as the commander of the Brejik's Run Outpost in the Tularan Marsh region.
By the time security in the main relocation zone had been greatly improved with the help of Republic operatives, the rakghoul population had retreated to the outskirts and began attacking outlying outposts more frequently. Having lost many of his men to the rakghouls and other enemies, Jazen had all but given up hope that the situation would improve anytime soon and was willing to withdraw his remaining forces and evacuate all the civilians back to the central zone, against Governor Saresh's orders - despite the best efforts of Vealo, one of the governor's aides assigned to the outpost.
His hopes were renewed when the same group of operatives arrived at the Brejik's Run and dealt with many of the problems that threatened the outpost. When everyone began to report to the major about the work done by the operatives, he canceled the evacuation.
