Repaying

Ryu walked across the universe, sweeping a gaze over a direction that had a direct line of sight toward Sarriel. But in the end, he didn't choose to say much of anything.

He wasn't at the point yet that he could just read someone's thoughts from such a large distance away. The main reason he had sensed it was that Sarriel's pining was particularly tortured and her soul was undergoing a great amount of fluctuations.

The reason powerful Gods could feel when their name was mentioned was due to an interaction between Fate and a spoken name. Usually, if one was just thinking their thoughts in their head, they wouldn't influence the world around them, and thus such a thing would never be triggered.

But by comparison, Sarriel's soul was undergoing a great upheaval and she seemed to be on the verge of some sort of breakthrough. Because of that, her soul was influencing the world quite greatly.
