After he'd returned from the past and reformed his cores, the system had said something odd.
[You have comprehended part of the Void!]
[You have comprehended part of Nothing!]
[You have comprehended part of Dissonance!]
[You have comprehended part of Resonance!]
[You have comprehended part of Harmony!]
It had said he'd comprehended Harmony and Dissonance, which was abnormal considering the fact that Uriel simply hadn't.
This discovery had led to his bottleneck regarding his cores and the tri arts, an issue he still had no solution for.
So then, by witnessing the birth of a dimension, what had he comprehended that'd been so potent that even the system deemed it necessary to point out?
What had he seen?
"Unfold."
Uriel spoke, resonance laced into the very fabric of his voice, his cores humming as he bound himself not to the ambient fabric of aether, but to the fabric of space around him.
He closed his eyes.
Then, his Simple Domain unfurled, and he spoke again.
"Unfold."
