No Return Pass was a place that could be considered nothing but a death sentence for those stationed there.
It was a portion of Eien sectioned off from the rest of the ring with walls that reached so high even the sky was contained within them. In this total darkness, a never-ending wave of Nox had been assailing the universe for tens of thousands of years.
It was a land of no return, and it was named as such because hiding this fact behind a grand name was not a grace No Return Pass deserved.
There was no option for retreat.
The domain bordering the Abyss behind No Return Pass was none other than the Human Domain.
Spatial distortions that could kill even the greatest experts filled the space between the Human Domain and Eien, which acted as a second line of defense against the invading forces but couldn't be the first.
Because with the numbers that were pushing through the pass, the spatial distortions could only hold them for so long.
