Speak with Rally Zapnabber to use the Zephyrium Capacitorium. Return to Tally Zapnabber at Toshley's Station.
[player], I raised the efficiency of the Zephyrium Capacitorium by 30 percent. That will launch a test subject of your weight and wind drag ratio to new heights! Want to test my theory? This experiment ought to send you near Razaan's Landing.
Speak with Rally... he'll get you prepared for launch.
