Medieval Castle Hidden Numbers

In the far Middle Ages a beautiful girl lived.
She did not need anything, living in a luxurious castle, surrounded by dense forest.
Her parents are aristocrats from an ancient clan who did not deny her beautiful daughter.
The baby grew up like a princess, and when she became an adult, she turned into a real beauty.
All prophesied to her the same handsome groom, at least from the royal family, and a cloudless future.
But no one imagined that out of the thick forest thicket, its darkest corners, the evil sorcerer was watching the beauty.
He planned to take the girl in his hands and dared to come to her parents with a marriage proposal.
Having received a predictable failure, the villain got angry and put a terrible digital spell on the castle.
To remove it, you need to find thirty hidden numbers.
