The Swamp Man Technology is precisely the opposite of this "desire" Authority.
Or rather, it is a perfectly complementary ability.
Jacob's Swamp Man Technology can create a soul identical to the original, with an identical body. It just lacks the original consciousness, and there's even a possibility of a completely new consciousness emerging.
Shaping the body is not a difficult task; for the Extraordinary Abilities in this world, it's quite manageable.
But this technology that "adds a soul out of thin air" is inherently unreasonable!
—Neither scientific nor mystical.
Because the total amount of souls in this world is more or less finite. If the soul of the deceased cannot become a Phantom Demon in the Dream Realm, it will be recycled as material for new souls.
