The fluctuations of the return portal contained aspects of space and time that revolved in quite the interesting fashion.
Since it was a product of the universe itself and not a practitioner's skill, it was far more complex, yet far more ingrained in nature than anything a living being could produce.
That was why Damien didn't feel strange as he stepped into it.
As usual, space and time warped around him. With his unique senses as a Spacetime practitioner, he was able to sense the corridor that was transporting him, as well as the others being transported by it.
The smooth breeze of space brushes across Damien's face. He looked around and saw the various spatial phenomena taking place outside the bounds of the corridor and marveled at them.
This sight was always something he could appreciate.
It was the true strength of space and time, that which existences within it could never reproduce.
