The Shattering

"A release of magic energy so powerful the very spot where the shattering occurred still vibrates with the intensity of the act."

This was the event during The Last Battle where the Reinhart Union - [LN]'s great sage unleashed the power of the Ulticron. Beams of immense power ran across the battlefield rending the land and vaporizing thousands of soldiers at once before shattering in a spectacular explosion. This event marked the destruction of the artifact.
