The Shattering taking place.

He must remember, he must be made to see, or the journey of 100,000 years will be for nothing. He hides beneath, preparing to meet his destiny. We must go there, we must right the wrong. So many wrongs before the Shattering can end.
Antidermis, through Brutaka, Destiny War.

The Shattering was a major disaster caused by Energized Protodermis leaking out of the core of Spherus Magna. It caused Spherus Magna to shatter in to three pieces, Bara Magna, Aqua Magna, and Bota Magna, the latter two becoming moons of the former, Bara Magna.

This event occurred soon after the Core War started, and ended the war.
