Prack was a male dispatcher working for the Navigators' Guild as a Pathfinder navigator. In the years leading up to 19 BBY, a Chiss individual arrived at the Navigators' Guild's Guild Concourse 447 space station seeking a navigator for a diplomatic mission aboard their Chiss diplomatic cruiser, destined for the Unknown Regions planet Bardram Scoft. Prack inquired among the available navigators to see who desired the assignment. Receiving no volunteers, the dispatcher assigned Pathfinder Qilori to navigate the Chiss craft. He notified Qilori of the Chiss's destination, and that he was unaware of the purpose of the mission, directing him to gate five while ridiculing the nature of his assignment.
