On the last day of April in Sky Era Year 118, the entire sky was plunged into panic, for war was coming!
More than ten large forces and families, along with numerous Independent Sky Cities, launched attacks on the Sky Alliance during the final days of April, a message spread by the Shadow Alliance to every corner of the sky, not only letting everyone know that war was coming, but also filling each person with a sense of personal danger.
Although since the beginning of the Sky Era, the sky had never been at peace—old eras had been phased out, and old systems had crumbled, propelling the world into a new era and causing constant warfare in the sky—these conflicts were usually very limited, mostly between a few Sky Cities or among certain forces, hardly affecting the entire sky.
But this time was different, for this time the one being attacked was the Sky Alliance!
