Sky cannon

The Sky Cannon was a massive weapon constructed within Mount Yeroc on Tahlboor by an ancient Tahlboorean civilization. It ran off the power of the planet's inner core, and they hoped to use it to sculpt their world's surface and change the tides by altering their twin moons' orbits. It destroyed one moon and apparently caused the fall of their civilization. Around 5 BBY, Jake Harthan tried to cause a genocidal war between the Troobs and [Hobor]]s to give the Tion Hegemony access to the weapon.
