"You are my most trusted son because I believe that, unlike your brothers, you use your brain but leaving your only son to grow fragile and unprotected in this turbulent time was simply insane! Is this your child-wife's idea?"
Karl lowered his head for his father was right. He tried to talk against it with his wife but she was hellbent on her decision to let Calixto grow into a young adult before he took the magical powder from the Witches of the North.

However, his first wife told him that her decision to let their son grow into a young man was a suggestion from one of the witches that happened to own her a great deal when they were still young practitioners of magic.
