"I am impressed with the discernment of your whimsy," Kithabel remarks to Sherlock. "It's possible, though, that we can't actually omnipotence you, Jewel - requires a certain compatibility with a person who wants to at least temporarily turn into a dragon, installing the omnipotence has some mind-affecting effects that I predict may not bother you at all but might disturb candidate dragons, and I suspect that my omnipotence doesn't reach as far as determining dragon-compatibility in a foreign magic system so we'd be crossing our fingers and hoping a resurrected unicorn can do it. Maybe I can just open the door to that world and ask a unicorn if that's possible at all first."
