what is this, an art history lesson?

Mercury was surprised when the girl took his words as an invitation. Heading into the armoury after him. He eyed her critically for a moment, opening his maw to gently scold her, when she placed a book on the floor in front of him. Despite himself, he found his eyes travelling downwards, intrigued. She tapped an image, and his eyes moved from the leafy bookmark, to the picture drawn within the book.

Instead, he found himself fascinated by the young girl. “Now. You need to be aware that you can not enter this room without an adult present, okay? There's too many ways for you to hurt yourself in here.” He looked at her for a moment, to see that she understood what he was saying.

“This blade is made out of what the pack calls Carpathius steel.” He said, gently tapping the page himself.
