Sacrum.
It felt odd to step back into this place after so long. Of course, this wasn't due to a suppression of sorts. Due to the fact he was born in Sacrum, no matter how powerful Ryu became, so long as he was careful not to collapse reality itself, he could always return.
Rather, it was because he could sense things now that he never could in the past. He could almost "see" Shrine Mountain's looming presence, infusing itself into the very vibrant life of the world. And it was precisely due to this that he could feel just how special Sacrum was.
Most of it was constructed of what one would expect from such a weak world. But, hidden within, there were tendrils of laws that reminded Ryu much more of the True Martial World.
One had to wonder why it was that a Clan like the Martial Gods would be so interested in a middle world. The answer to that was obviously the Shrines, but why?
