The Mascot Moon of Carida had the Cliffside logo carved on it around 5000 BBY. In 8 BBY, as a prank, Mako Spince stole a gram of antimatter and tried to use it to blow the seal off of the moon. Unfortunately for him, he underestimated the power of the explosive, and accidentally destroyed the whole moon. He was expelled from the Academy as punishment for this.
