"Weapons?" Annie shook her head strongly. "Even if you allowed them to be made, I wouldn't be interested in creating weapons. I have seen enough war and world devastation. Probably enough to satisfy the curiosities of a dozen people. I have no interest in weapons. Little doodads that do interesting things, stuff to help people, even projects that will benefit everyone for whatever reason. But not weapons."
She made a face. "I give you my word that no weapons will be created."
Even if she accidentally made one, she'd dismantle it before anybody even got to find out what she'd been working on. Annie wasn't a pacifist by any stretch of the word, but she had no interest in being the creator of something that was used to do harm.
