Armou curiously gave it to me saying that they offered to experiment with it. It is not normal for someone to offer themselves like that, I warned him that the process could last a few months and it would hurt a lot, but he insisted. He told me that if I could make him a kind of strong living being, in exchange he would do what I told him. I liked her very much and I told her that when this was over I would only have one task: to watch Spartora and tell her what I ordered her to do. He could become a shadow and better monitor Spartora, he could also manipulate other people as he pleases and time without it affecting me. They warned him that they would still have him under control and that he would have a shock chip if he thought of hurting anyone in the laboratory or the creator. He knows that the creator is a kind of goddess in that world, so he wouldn't dare hurt her either. I ended up being half demon and human, I could breathe and swim perfectly underwater too. After finishing being experimented he would be free with but he would still have to keep an eye on Spartora. And he became a good friend of the creator too.
I know this isn't the best story but it's all Armou came up with.
