As someone who has managed to become a child of the plane twice, he believes he has a say on how overrated the title of the child of the plane is. The Vampire on the other hand believed that what he said was nonsense. 

The vampire scoffed. "Overrated, he says. You are speaking in ignorance. Do you know what it means to be a child of the plane? How many children of the plane do you know? She is a rare existence meant to be a channel for the combined power of the plane."

Ragnarok fell silent. He didn't say anything despite having a lot to say about the title of the child of the plane. Sure, the Emperor will be much stronger than Soverick because of her POWER stat, which Soverick lacks. Her POWER stat will help her fully utilize the connection to the plane. But that doesn't mean Soverick can't kill her.
