"Oh, unless I find... another way, I'd be more than willing to pay the price. One should never put personal interest over the ever marching progress of science, after all. And it would bring me one step closer to my goal. A leap, actually. Is there any magic involved in the process though, or is it a purely physical matter? I'll have to take blood samples once we get out of here..."
Victor twitched, and his attention was about to turn to Akor when he remembered something.
"Oh, and do you drink animal blood too, like the lessers? There is quite a supply of meat, just up those stairs"

Victor now circled Akor once more. He then extended a hand.
"Very pleased to meet you. My name is Victor von Ravenstein the Third. The girl is Cassandra, a monk, but I know little else about here. She's proven a useful enough companion though. I wonder, does your condition bring you eternal life?"
Victor bends forward to whisper something in the halfdragon's ear.
"Why the kids? Sacrificial victims? Slaves to some strange desires you have?"

Looking at Umber he says "It's the speaking variety, right?"
