It was the week before the Fifth Grail War and all was proceeding as it normally did, at least for the majority of humanity and the moonlit world. Some thought that they could sense change on the winds, the looming shadow of something waiting. Which to be fair was not exactly all that different than the usual Wednesday evening in this neck of the cosmos. Even as plans were made, as forces were marshalled and resources readied, well the plans of mice and men are subject to sudden and drastic changes at the best of times.
It appeared suddenly, the creatures face projected on the skies, its voice booming over the land, all of humanity (and more besides) able to see and hear it. "Greetings people of Gaia. So, the thing is thanks to a series of poor choices and more then a few gambling losses, the incarnation of your planet went deep enough in debt that normally they would have been consumed by other iterations of the world. But hey, good news for you, I thought that was a bit of a waste!" The creature smiled, green lips not quite mocking as red eyes sparkled with amusement.
"So, I bought out her debt and am now her legal owner. Of course, I am working to restore her to health and well being. But of course, then there is the question of humanity. On the one hand, frankly I'd be in my rights to kill or deport the lot of you." The creature shrugged, as if the displacement or death of an entire species was nothing at all to it. "But frankly, given your totem spirit and squatters rights that would be a headache and a half to deal with. So instead, humanity is now being charged rent. And there are some rules."
Oh, how the creature grinned, clearly repressing a giggle. "Firstly, I'm a capitalist and part of MWESBA." The creature paused. "That's the Multiversal Workers, Entrepreneurs and Small Business Alliance. Now, we have firm rules against Marxism and Communism and sadly due to your totem spirit, I cannot just resort to orbital bombardment to deal with the problem. So instead any members of those death cults will be subject to cancer that will go into remission if they honestly and sincerely recant."
The monstrous beast shrugged, as it continued. "In somewhat related news, all bio-warfare weapons have been disabled and rendered harmless. And before you all throw a bitch fit?" The creatures eyes narrowed. "I'm on the hook for massive fines if I don't deal with them. As it is, every government that has been willingly producing them is getting their souls shipped straight to the local Hells regardless of whatever else they did in life, and that was the policy BEFORE I bought up the debt." The figures looks not very amused at this. "Because, and repeat it with me, biological warfare is bad, m'kay?"
Hands going down, the herald of doom had one last very important announcement. "Now, for all the magi of the world. Rejoice, your magecraft is no longer subject to diminishing! Tremble, because you will need to complete the test sent to you in the mail in order to retain the use of your magical abilities after the month is up." The larvitar paused. "Frankly, most of you are going to fail, and fail miserably." There was no bitter edge, nor a gleeful one to that statement, even as proud Magi rushed to check their mail, to find the packages that could very well spell their doom and the doom of their lines.
Many looked at the eldritch and potent documents, and as they opened and began to read, shrieks of terror and hate, of loss and incomprehension as they grappled with something all of their power and legacy left with woefully unprepared for. How many ancient legacies were dashed on link and paper? How many failed a simple Ethics and Morality exam? How many found basic humanity and decency to be alien concepts?
Enough that one could say that the powers of the moonlit world could never be the same again.
