Ryu had spent most of the last several decades of his life in an idle. Most of the time in the blackhole's range was spent repeating the same monotonous task again, and again, and again. As such, especially with the strength of his mind, he had a lot of time to think about other things.
In one of his many streams of thought, he thought about how important the Soul Quintessence was to Sacrum. It was a legendary Realm, one that even Sky Gods could reach. And he couldn't help but wonder…
Just how much of that was due to Sacrum's weakness, and how much of it was a hidden truth that lay right before his eyes? What was it about Sacrum that made the Soul Quintessence Realm different?
If he thought back, Sacrum didn't have concepts for the Sky God Realm, at least not in the general sense.
