One year has passed since the Lunar Tragedy. As the seconds tick by, the Earth remains caught in a state of shock and squalor a living testament to the destruction that "mere" human beings are capable of. In but a few moments, the work of terrorists brought about the explosion that would change everything. With a single push of a button, the whole universe stood still for a moment in time. The test facility. The colony. The moon itself. All gone, save for the sickly, heavy ash that still hangs heavily above and the chunks of stone that still drift down from the sky. The meteors were far from pretty or harmless. As the debris of the moon fell to the Earth, cities were leveled brutally, killing hundreds of thousands, if not millions of people.

The losses were unspeakable.

It was undeniably something that would put both the Terran Union and the New World on edge. After the Tragedy, the New World had fallen to confusion, splintering into factions amidst the ruins. What could they do? Their main colony and headquarters were on the moon, after all. There was no guidance, nothing to save them. It did not take long for an ambitious new leader to rise up and seize control of the situation. Leon Toussaint, a high ranking military officer, brought the shards together and created the Broken World.

Morale was low—no—non existant on the space colonies, and it was more than easy for Toussaint to convince the scared people that the attack on the Lunar Colony was not by terrorists, but by the Terran Union Forces.

For the first time since the Mobile Suit War, war broke out and chaos once again snaked through the ruined world.
