The angel expected this. Indeed, she had just suddenly called them over, so it was a bit much to expect that they would all outright believe her. She smiled and began to explain herself when the one known as Yousuke bent forward to touch her wings. As soon as he did so, a pang of warmth shot through his fingers and spread throughout his whole body. On the First Day, stretched her wings, covering Yousuke's back like a blanket.
"Are you cold perhaps?" she asked. "If it is warmth, then I can provide you some, though we should hurry on."
She cleared her throat to get everyone's attention once more, and began her explanation.
"In the universe, as vast as it is, there are somethings born of natural causes, however, their effects on the world are anything but," she stated. "These are known as 'Disorders' they are like a virus; they latch on to something that can hide them from our eyes, that prevent us from knowing where they are. They grow and fester, until they become strong enough to take a form of their own. Then, they begin wrecking havoc on Reality, because they do not follow the rules set up by Reality since the dawn of time.
"Still, even then, they are a minor threat. The full threat that Disorders present is that they can become catalysts for True Devils. Once they become powerful enough, they can become hosts, a sort of fetus for the Devils until the time is right to be born. When they are, no matter how fast we Angels react, destruction and evil will spread at a tragic rate."
On The First Day paused, allowing that information to sink in.
"Despite this, as beings bound by Ancient Rules, we are unable to go down and find the Disorders ourselves; interacting with humanity cannot be done except in very special circumstances, such as right now. Thus, Virtues of Heaven such as myself often employ human agents to act on our behalf; priests or prophets, if you will.
"Each of you here were called because you posses the capacity to accept the gifts that I can give you. How or what determines that capacity is a mystery even to me, but the fact remains that I know you have it - for after all, you alone are the ones that accepted my summoning. I present this knowledge to you. Should you accept my call, then the gifts I have at the ready are yours, if not then I will send you on your way, unmolested. If it is desired, I can even remove all memory of this meeting from your minds, to preserve what you know about your ordinary lifestyle.
"My Lords and Ladies, I, On The First Day, humbly ask you to accept this task, and to do everything in your power to assist us."
The Angel finished with a deep bow, and her wings briefly glowed golden. A sudden flash of insight filled the thoughts of everyone - they could all see it; the different universes, the gifts that they would recieve, and even tiny hints of how a true Disorder looked like.
