Draco was trying to work on the formula from earlier, since it was a key factor in her experiment, when she heard Axel in the cave. Draco sighed and decided to deal with him first since she couldn't have him messing up her research on accident, or on purpose. Draco walked out of her lab made specifically for working on Dark Magic and saw that Axel was in the artifact room, and about to mess with one of the artifacts. Draco said, "DON'T! Touch! Anything. If you value living a long life free of curses. You need to leave here and don't ever come back into this cave, do you understand? It's very dangerous in here and the less people there are, the safer it is for everyone. And don't talk about this with anyone, do you understand?" Draco was obviously not joking around and her facial expression was too serious for it to be a prank. Draco knew that Axel would figure out pretty quickly what the artifacts around them were. Draco said, "I've been trying to make spells to counter this magic, and cure those afflicted by it, like my Uncle...Anyways, you need to leave this cave. I'll tell you more later, right now I have to work. My Dad or one of the other guild members can tell you a bit more." Draco was trying to make it clear that she was trying to use the spells for good instead of evil, so that  Axel wouldn't get the wrong idea.
