He has all their attention. So he started speaking to them. "I suppose an introduction is in order."
An introduction is in order because he is not the same Soverick that began this competition with them. He has changed. He has become his real self. They will be facing his real self from now on and they should know that. Whatever they thought they should expect from him will be overhauled. They will be underestimating him terribly if they stick to his previous image. His previous self was nearly unstoppable. He is actually unstoppable right now.
"I am Soverick Ghastorix. I am the child of the plane."
Everyone in the area for 100km heard him. He did not amplify his voice. No, his divine sense spread out that far to speak with them. That isn't the limit of his divine sense too. It is still spreading.
He said to them, "Today we have gathered here to judge me worthy."
Then he began to laugh.
