Use the Robotron Control while standing near the Concealed Command Console hidden in a small cluster of bushes on the rim of the needle closest to Thalanaar to take command of a Robotron 3000. Pilot the robot to the western edge of Thousand Needles where the Alliance outpost of Thalanaar is located. Use the robot to collect a sample of the moonwell's water and return it to Wizlo Bearingshiner at Whitereach Post.
