"Er, let me think." Vanyel closes his eyes. "It's hard to predict what he's thinking, but... First off I think he would see you as a threat. Since I assume his default plan is still to conquer Valdemar, even though it seems like he's willing to put some effort toward, I don't know, convincing me to...ally with him, that he's in the right right, convince me of something anyway. He might send an assassin or kidnappers. I'm pretty sure he tried to have me kidnapped right after I was Chosen."
Long pause.
"...He'll be curious about you," Vanyel adds finally, in a softer voice. "He knows everything about magic in this world, I bet, but here you are, coming in from another world. I don't know if he knows that there are other worlds. He'd want to know everything about you, your magic, Arda and Materia... And then, maybe he'd try to be convincing at you too."
