Of the calamity that looms over us after "today". It began from the earth, and would eventually grow to encompass the entire planet, spelling out true ruin. The Council of Fourteen… well, I suppose they were only Thirteen by then, decided to bring into existence the "Will of the Planet", and by doing so suppress the calamity. But such a massive act of creation required an equally large amount of aether... And so half of the survivors gave up their lives to serve as the source of the aether. And thus was Zodiark born according to their plan, and the calamity dealt with.
