Zegris

Zegris is a technically-unsophisticated planet with twin moons—the closest one is named Zo'Etha. Deep within the planet are strange square rocks which are sometimes brought to the surface by environmental disturbances. They're mostly a hazard for the Zegrins, who are lizards and have no use for such things.

Fiction

TransTech

The Decepticon Killzone crashlanded on Zegris in search of energon. He proceeded to go on a long rampage of destruction across half the continent, eventually ending up at the capital city of Zoruul. At that point, his rampage came to an end when Jackpot and Hubcap fell on him from an interdimensional portal. After High Priest Yurgeth filled them in on exactly why Killzone had come there, the two Autobots were happy to arrange to contact the other Autobots to bring resources to help the Zegrins rebuild.
