so apparently Cecil’s mother is the grand witch or sorcereress and when Cecil awakened her power, she succeeded her mother. Also the 3 maids that took care of her are her guardian witches.
And the saintess have the power to alter their world because she still the writer and the first things she did
is alter the wealth of Kane and made him a duke. But that is not their goal their goal is to make the Eugendiph's blood disappear at first they did not succeed but at the end they succeeded.
After all of this they will have a son with green eyes and blond hair like Cecil but his face is the exact copy of his father.
