Kayden felt the soul contract binding directly to his soul like a sword; at the slightest sign of disagreement with its terms… he would die, his soul torn apart. Fortunately, it was just a soul contract and not an oath sworn by the gods. Likely, it was because swearing by the gods was far superior to this; moreover, only deities could enact such contracts. Practically no mortal in the universe was capable of manipulating souls, an ability reserved mostly for the gods. The ability to manipulate souls was rarer than the ability to manipulate time. Now, with the gods departing, most organizations would avoid making oaths to the heavens to avoid bad luck.
