Kaiba was apparently surprised by the fact that such information survived in Atlantis without them using that to their advantage. Perhaps he hadn't been talking to the other people within Atlantis very much. "More like, they were incapable of using it. As until about a week ago, this place was a cesspool for the worst of sentient lifeforms and all of their bad habits," she said with a bit of a smirk. It was said by the common folk of this place that they didn't find deliverance properly until the travelers showed up. But she'd gotten that information already, hearing that Atlantis was open for business again had lead her to the blueprints that would make going upwards to more interesting things possible. If of course, the lad with her would actually quiet himself long enough for her to think.
"No, it wasn't finished by the time Atlantis fell. And it didn't become complete afterwards, either. I am probably the first person to look at these in quite a while," she mentioned with a sigh. Her smoke was finished and it was put out immediately following her sentence within a tray off to the side. He was quite right, she hadn't finished it yet. She'd taken her own design starting from the base, making it able to dock, both at sea and in the sky. She'd gone out of her way to develop the proper steering system, made it mechanical with a hint of magic. What she was missing was sails at this point and what Kaiba had to offer again was Dragons. "It's like beating a dead horse with you..." she said with her head tilted to the side as if confused only for a moment. A dragon to drag along the rest of the boat would be nice, but there was no telling if a creature a living one would be okay with such a thing. Actually.... "Quiet."
That was all the lass said for several moments thereafter. Her mind was calm again. She'd been trying to rationalize what kind of system to use to move the boat, but Kaiba and all of his incessant prattling about Dragons was actually a bit helpful. Maybe. She moved aside her other drawings and began sketching atop the light table an image of dragon wings. Diagrams of them opening and closing. The fins at their tails for maneuverability. Dragons held dominion over the sky for a reason. Kaiba's obvious favoritism aside, this version of the 'sails' was probably the best and basically a combination of all of her previous ideas. "Oh, that's pretty good." she mused. Actually her own machines were less magical than they could be, but obviously she'd developed quite a few things to work with the magic of this world, like her Dragon Radar. She began compiling a greater list soon after, some other things she'd need to make such a thing more feasible. She was fairly open to working with and sharing this idea with Kaiba, as it was partly his to start with, besides, she had no real idea of how to create a Dragon and it was obviously his line of expertise. "Come on then, I assume you have an idea in mind or all that talking was kind of pointless."
