Nojin Koolb was a Human of the male variety who served as the governor for the planet of Xartun in the year 7 ABY.
In the time immediately following the Bacta War, Koolb made a deal with Warlord Zsinj to secure protection, even though Xartun had only recently signed on with the New Republic. He told Garik Loran, a commando from Wraith Squadron who was posing as one of Zsinj's underlings, that he was loyal to the warlord.
