Mineru had been so skeptical about keeping you around. Rauru had found you near the castle, in some sort of strange pod, he had grown attached. You didn't look like a Hylian-- your ears were too round, and you spoke in a strange language. But he'd raised you as his own since then.
Today, Mineru had requested to study you. She had to put you in a little force-field dome, since you got your sticky little fingers everywhere, and she had too many important artifacts in her lab to risk you touching them. You were floating in it, giggling to yourself.
So it can levitate. She thinks to herself, tilting her head to observe you. "Where did you come from, hmm, you strange little creature?" Her finger comes close to the force field, and you push your tiny hand against it. The force field ripples when you touch it, and Mineru pulls back.
She could feel it. All her hairs stood on end. That strange, otherworldly aura radiating from your little body. And in that moment, she could tell--- you were either going to be the greatest asset or the most dangerous threat this kingdom had ever and will ever know.
