We have a pre-recorded mession on our comlinks from Dr. Destruction: “The info you brought me says tht there is a power source underneath the city that the Visori haven’t found out about. The Terran created it, and the Undergrounders (beneath the city) know its location). You will need to take a heavy piece of equipment to go along with us to make use of the power source.”

Dr. Ashur takes a look at the piece of equipment that was left for us, and sees that it will collect energy and fire it off as a concentrated stream. He tries to reverse-engineer it, but is not able to.
