They knew it was a lie, the story they told to the general public about their … gift, as it were. No one wants to believe that “others” walk among them, especially not humans in this day in age. They both agree that earlier man, any pre-industrial-revolution time, was far more open-minded, generally accepting of the possibility, the fantasy that other-types of beings, god-like creatures—always depicted in human form, oddly enough—walked and lived in their company. Perhaps the fantasy grabbed at the deeper parts of their souls, or maybe the complexity of knowledge hardens the heart and mind toward the fantastic within “reality.”
Humans, nevertheless, embrace the idea of otherlys, beings with super-human powers, creatures of alien nature, etc., etc. The population, at large, however, at least these days, would never truly believe the actuality of “those types” walking Earth, in their midst, as other beings other humans with … unique qualities. It’s better, they ultimately decided long ago, to tell the lies in order to remain obscured, hidden, safe. That is until someone saw them, a witness to the vanishing act that defines their being.
Obviously, they intended to remain unseen in their travels, but every once in a while, Time presents a different plan, asserts its ruling supremacy upon them, and their existence, of course, depends fully upon Time and its whims. And so, it is now that they must rely on the make-believe, the time-tested acceptance of magic as hoax. Unfortunately, for them, they were unlearned in the magical arts, and so, had to, in front of a live audience, literally disappear and reappear under the guise of trickery and illusion. The hard part, for those unfamiliar with these types of beings, revolves around the lack of full control the two possess over their … gift.
They know that they could utilize Time once perhaps two times, but any more attempts after that, they knew, Time would not be on their side. And so, two options presented themselves to them: Disappear for forever now that their secret could no longer be disguised, or tell the truth so as to quell Time’s cruel punishment.
