The heartbreaking howls of monsters that look like wolves, but are more terrifying, start the movements of other monsters. There were also bears, tigers, and other types of beasts. All of them were animals that were unique to magic and then contaminated by black magic that suddenly appeared without anyone knowing the explanation.
There were two theories. The first was that it was a kind of magic that came purely from nature and wasn't originally black magic, but because of man's bad deeds against nature, it changed form and contaminated the animals that were closest to nature.
Second, it was black magic that was stored in an object by a black magician. The object that stored the magic then accidentally contaminated the animal that possessed the unique magic.
The most important of all the theories was how the animals became monsters and went wild.
