You peer through the hole, and begin extending the instruments you always have at hand for these sorts of experiments to gauge what's within. Temperature, normal. Air pressure, normal. Humidity, normal. Everything about the inside of this realm is entirely normal. Of all the various states of being, of the infinite variability of reality the Winds have apparently created new reality that is entirely typical for this place.
So what does that indicate? That when forced into the barrier between reality and unreality, Vitae undergoes a transformation into... what, into nothing? No, into empty space where previously there was none. There's nothing there, but there is a there there to contain that nothing, where previously it was not. How? Well, Vitae was the substance of the realm of Aethyr, so transplanted to where there was no realm, it creates some more. But what you're looking it is certainly no Aethyr in miniature, is it? Well, no, you don't know the ground state of the Aethyr, you only know it as it is with the many Gods in residence. It could be that without them, the Aethyr would just be emptiness? But isn't the Aethyr inherently psychoreactive? This little pocket you've created doesn't appear to be. So it's not mimicking the Aethyr, it's instead mimicking reality? Could it have been imbued with... reality-ness from its time as Vitae? Or was this tiny, nascent realm of Chaos overwhelmed by the weight of a much larger reality through the pinhole that the Vitae had escaped through?
No. You've tested Vitae in every way imaginable and know that it is unreactive, its nature unchanged from the moment it bled through into reality. This effect must rely on the inherent properties of the Winds it created. But that would mean that when Winds are presented with a blank slate and transform into a realm to fill it, they birth normality. But that makes no sense - the Winds are the energies of Chaos, aren't they? Well, no, not quite, that's why they're legal when Chaos Sorcery very much isn't. The Winds all represent facets of the real - life and death, light and shadow, passion and instinct, solidity and ephemerality. Mainstream theory is that this is the energies of Chaos having the nature of reality imprinted upon it when too far from the attention of the beings that command it.
And there is no weight of reality here. Your lab is magically isolated from the outside world, and the Aethyr was forced into a space between realms before it transformed. Placed equidistant between real and unreal and isolated from the pressure of existence to impose a decision upon it, Aethyr still became Winds and the Winds still retained the nature of reality.
Which means that the Winds can't be born of the mere inertia of what already is. Reality is being imposed upon Chaos by something other than reality.
