There were many kinds of Heavenly Ghosts. Under a low standard, even Ancient Gods could be counted as them.
The first and most numerous kind was the random, unstable type of Pseudo Heavenly Ghost.
They might comprehend some trait tomorrow, or countless years later. Most Ancient Gods were like this.
The second kind could be called Information Manipulators.
They could stably alter the information of things. As long as they wished, they could alter anything.
Everything in the world possessed information. For example, a ball of fire might have a temperature of 2,500 kelvins and a volume of one cubic meter...
This kind of Heavenly Ghost could alter its temperature to 250 million degrees, or even two trillion degrees—it made no difference. This alteration was absolute. It followed no principles and required no energy, as if the fire had originally been burning at two trillion degrees.
However, simply altering information could not raise the temperature of a flame to infinity.
That was because the total mass-energy of the universe was not infinite. In theory, heat had a maximum limit.
In other words, alteration could only freely modify something within the range permitted by its own information. It could not exceed that boundary.
Exceeding the boundary was called creating information. Since there was no infinitely high-energy fire, altering an ordinary fire into one with infinite energy was not alteration, but creation.
Thus, although the alteration was absolute, its scope was not infinite.
Some Ancient Gods could perform Substance Alteration, but only into specific things—for example, turning anything they touched into bronze. That did not count as being an Information Manipulator.
At the very least, one had to be able to alter all information one could perceive to qualify.
Even among Information Manipulators, there were great differences. Some required a price. The
