Many thanks to my dear friend XD for helping to proofread for weird grammars, spellings and whatnots.
Clear Blue Skies
Prologue
The final battle. The hidden battle 100 years ago between the chosen warriors of God and the children of God was now nothing more than a page in some faraway land's folklore. And needless to say, no history textbook made any mention of it, either.
It was a battle to end it all, but it didn't. Though the Exorcists dealt great damage to the Noah Family, they still did not manage to kill all the Noahs. The Earl was forced to retreat with his remaining family members, slipping away into the darkness to recuperate. At the same time, the Black Order crumpled, with its remaining few Exorcists finally surrendering to the much awaited rest from their dramatic and bloody lives.
No one knew if there was any effort to rebuild the Order, or search for new accommodators or heck, nobody even knew what the Vatican was going to do. The innocences were put away, hidden, lost. The war had seemingly been forgotten by humans.
But not forgotten by the Earth.
The battle had actually damaged a great part of the Earth's environment and natural healing ability. Unable to recover from wounds the innocences and Noahs had caused during the final battle, together with the massive pollutions caused by the advancement of science and later human's warfare, the world's environment steadily became harsh, corrosive and inhabitable.
Gas and ashes clouded the skies, creating a constant grey that no blue could break through. The air became stale and almost unbreathable, burning the airways of those who dared to breathe too long in it. Occasionally, it would rain but the water from the skies was no longer refreshing, but acidic and burning.
What was more, the remaining akumas that had become strays without their Noah masters continued to endanger the lives of unknowing humans, especially those who traveled outside, willingly or unwillingly in the harsh environment.
Along the way, some scientists realized the irreparable damage Earth was suffering from. Alliances were formed. Research started, work started. Some strong forces appeared and took over to lead the remaining mankind.
Gigantic cities isolated from the natural environment were created and humans dwelled in them, protected from the harsh environment and akumas. Artificial nature environment and weather were created within the cities to make the citizen feel like they were still part of the Earth. But traveling between cities was almost impossible and many grew old and died without knowing about the world outside.
And sunshine, blue skies and refreshing rain were all now nothing but beautiful legends.
