You would think, that something crossing distance instantly, apparently even from the perspective of beings who can already move at infinite speed, would be impossible to intercept.
And from a typically chronological perspective, you might be right.
But what about if you looked down from a higher dimension of time, from a higher level of existence?
Or ten thousand of them.
The skeleton and his horse are crushed instantly, somehow before they can even react despite the instantaneous movement.
Something vast appears within the space, its smallest movement threatening to destroy this world. But even this massive entity is merely a small cut of the true being.
As NACHILLEMORAC concentrated, each one of his parallel wills sent a projection of himself up to a higher dimension. And there, the projections found a poor n-dimensional being, and they focused all their hypnotic power on him... and dragged him down to hell and devoured him. His entire essence, the essence of one from those vast multitudes of higher dimensions of existence was absorbed.
And then, knowing what came next, these projections absorbed each other, until only one was left with the full essence of a greater level of being within him. And then, without projecting itself, it shifted down through the dimensions down, down, down, all the way down until it found the right place to renter the world... and it did so with an attack imbued with all its powers imbued with the essence of vast multitudes of higher dimensions and levels of existence, the fist of an outer god smashing down through space and time to crush everything below it.
The entire infinite subspace and everything within, including NACHILLERMORAC, all his parallel wills, Colzin, the Pale Rider and the ultimate void is absorbed into the higher dimensional form of NACHILLEMORAC.
