Of course, this impatience drew the attention of a third party. The demon God didn't notice Ragnarok but it surely noticed this unborn Empress. It is fighting the Will of the plane so it noticed that the movement and actions of the Will of the plane within a living being in the plane. The demon god began to move its forces to eliminate her.
The will of the plane knew that its activities wouldn't go without being noticed but it did it anyway. It did it for several reasons. The first reason is the chance to mold the Empress into a bane to Vampires. So it swapped out the law of earth in her divine ability for something more dangerous to Vampires.
The second reason and the most important one is the supply of infinite energy that the fetus will get through their connection. This will ensure that the fetus grows to its best potential and also speed up the development process. That wouldn't protect the new child of the plane. After all, potential is not equal to strength.
