I'd like to open with a quote from Urvel Dulni:

"Change is inevitable. Indeed, it is sacred."

As this scholar has said, change is utterly inherent to the Amarnath. So intrinsic to it's denizens, in fact, that it may be embraced as divinity.

Let us renforce this notion with additional sources:

As the mildly astute may infer through mental hyper acceleration, polar fluctuations must at some point within infinity reach a conclusion. Furthermore, this passage discloses to us that the Aurbis, in it's entirety, may be viewed as infinite, thus immune to finite mechanisms. However, the pockets of existance within perhaps may not be viewed in such a way, therefore susceptible to such processes.

Let's review another fragment from this text (inserts are mine):

Due to the process of realm disintegration described as gradual, we must discard the notion of infinite existance, in the outer realms, at very least.

If we are to embrace the truthfulness of this text, existence of the Aurbis must be subject to finite events, such as the fading of exitance into pure potential, or none, respectivley.

Hence, we are confronted with a question, two questions, rather. The first being:

How will existence ceace to be?

When will existence ceace to be?

These fundamental questions hold within them the potential to fully understand reallity. But first, of course, we must answer them.

The first is quite effortless to satisfy. Magicka will vanish from the void. The opposite is only practicable within Aetherius, thus, through elimination we anticipate the inescapable fate of exstence.

The second however, proves to be more challenging. Is this possible? Will the gateways to Aetherius be closed? Have we reached the vertex of existance?
