Note: This is a small clockwork that will probably appear behind you, not the tinkered crafting station.
Follow the homing drone to ( -272, -1, -40 ) Copy/waypoint -272, -1, -40.
Confront and kill Luthaz L'Xak.
Now you can, as an alternative, start the quest Crime Pays Someone at Freesia Lastchain ( -276, -1, -18 ) Copy/waypoint -276, -1, -18. WARNING: As Freesia Lastchain says, you will not be able to finish the original quest line. OR Return to Principa Haleene Sirinae and finish this quest and continue in this quest line.
