Sky Cannon
this strange device was located within Mount Yeroc, on Tahlboor. The cannon resembled a huge spotlight, and generated an intense beam of energy when activated. The cannon was controlled by Chief Nimodro for many years. Although he knew that his ancestors had used the cannon to communicate with the planet, he never really understood what they meant. He knew that the beam of energy was blindingly bright, and seemed to be most powerful near the planet's surface. The true use of the cannon was eventually revealed by R2-D2 and C-3PO, when the droids were in the service of Counselor Harthan. Shortly before an all-out war between the Troobs and Hobors, R2-D2 determined how to activate the cannon's communication functions. He used it to project a huge image of C-3PO above the surface of the planet, an image which was visible and audible several miles away. The cannon was actually built by an ancient, though highly technical, Tahlboorian civilization. They designed it to harness the power of the planet's inner core to carve the surface of the planet to their own design, hoping to create a paradise for themselves. They had planned to use the cannon to adjust the orbits of Tahlboor's moons, thereby modifying the tides, but they did not survive to see this goal achieved. Jake Harthan also learned of the sky cannon's abilities, and sought to undermine his father's work in order to gain control of the cannon. Thanks to the droids, he failed, and the Hobors and Troobs moved closer to achieving peace.
