Tag a a Di'Zok courier. To spawn them, speak to Queue a second time. He will indicate the courier's running up the ramp from the Di'Zok area below.
The easiest way to tag the courier is to run over to the top of the ramp around ( 1300, 112, -2232 ) Copy/waypoint 1299.98, 112.11, -2231.88. You only need to tag one of the two couriers, using the tagger Queue gives you. Run fast and around to the north or they will despawn.
Return to Germa Prash in Highton. ( 1275, 159, -2074 ) Copy/waypoint 1275, 159, -2074
