Karl witnessed the entire process with his own eyes.
In fact, twenty years of observation had made him very familiar with what kind of person the "Demonic Woman" Hecate Fischer truly was.
If Karno Fischer had been born in a fantasy world, he would most likely have become a wandering Taoist, uninterested in mundane affairs, abandoning the world of mortals, and traveling to the ends of the earth.
Then Hecate, who also embarked on the Path of Revelation, would be a natural-born enchantress in the fantasy world.
With a personality like hers, she was destined to be anything but ordinary and would become a special existence that caused many people headaches and fear.
Charlotte would be the first, but definitely not the only one to be "tested" by Hecate, and all those who had not undergone the "test" would probably be collected by Hecate as her "pets."
She was very fond of people, just as many people were fond of cats and dogs.
