Their Speculations

The emergence of any spell had to follow one principle: any wizard who met the conditions had to be able to cast it.

Otherwise, it could not be considered a conventional spell, but rather something like the blood-sacrifice magic practiced only by evil wizards.

Especially during the period when the classical magic system was fading from the stage, all spells that emerged had universal applicability. Wizards themselves were already struggling to survive; if spells with harsh requirements appeared as well, the chances of carrying them out would be even lower.

According to Jon and Grindelwald's joint research, this spell was closely tied to a wizard's bloodline.

Humans themselves were animals.

Even biologists in the Muggle world did not deny this. Humans shared common traits with animals and counted as one kind of animal, only having evolved to a higher level and thus displaying differences.

But even if the Human Race had evolved highly advanced external traits, it could not deny the commonality between humans and animals.

Take werewolves, for example.

Wolves and werewolves were essentially both wolves, just as Muggles and wizards were essentially both humans. That essence was reflected in their affinity for magical elements.

Whatever magical elements favored became their vessel. If it was a human, they became a wizard; if it was another animal, it became a magical creature.

But reversing that process was extremely difficult.

Ordinary wizards had no way to reverse the process by which magical elements became compatible with them. It was like creatures in four-dimensional space being able to manipulate time at will, while three-dimensional life could not. This was not a limitation imposed by rules, but a difference brought about by the level of life itself.

Unless one could break through that barrier and become another kind of life—become a god.
