Humanity believes it is at the forefront of knowledge, a conceit of its own intelligence. The Eternals and their numerous allies make a mockery of this assumption. The Eternals themselves manipulate space-time as we might crumple a piece of paper, it is a natural extension of their bodies. We lack the knowledge and technology to do so, though within the last few decades, we – that is the human race in general – have stumbled upon their secrets.
A first lesson can be found in something known as Calabi-Yau manifold. If you were to research this you would find:
“A Calabi–Yau manifold, also known as a Calabi–Yau space, is a special type of manifold that is described in certain branches of mathematics such as algebraic geometry. The Calabi-Yau manifold’s properties, such as Ricci flatness, also yield applications in theoretical physics. Particularly in superstring theory, the extra dimensions of spacetime are sometimes conjectured to take the form of a 6-dimensional Calabi–Yau manifold, which led to the idea of mirror symmetry. Essentially, Calabi–Yau manifolds are shapes that satisfy the requirement of space for the six “unseen” spatial dimensions of string theory, which may be smaller than our currently observable lengths as they have not yet been detected.”
It would just be a huge mistake to think of this as a modern concept despite the fact that they push our knowledge of quantum mechanics forward. For these understandings are old, ancient, eternal – and yet we have found examples of these concepts amongst artifacts attributed to the Cults of the Eternals, scraped into waxen diagrams and described through Sumerian and Hittite cuneiform records, and further afield in the depths of the Hindu Kush, drawn on walls of temples dedicated to none of the gods of the Vedas.
The Cults have known about the relationship of dimensions suggested by the Calibi-Yau manifold for thousands of years, and applied it to their magickal research. We can only guess of the powers that they have gleaned from this knowledge, though you can be certain it should be feared greatly, for it will not be applied in a way beneficial to humanity.
To the mathematicians and physicists of today, the Calibi-Yau manifold is a way to visualize the dimensions, deep inside the atom, or perhaps see the architecture of the universe itself. To the Eternals, it is a vital way into our world – to seek out every crack and crevice by which means they may pass into our world and make it their own. Like water seeping into a cracked basement.
We are never alone – and never have been – for the Eternals have cast a shadow in which we have dwelt for our entire existence.
