You can't read ancient magic books, especially out loud. These rules are followed by all researchers of the Sphere. Almost all.

Grix could be called a happy man: family, home, children, the position of chief researcher at the royal court. It would seem, live and rejoice. But curiosity let the researcher down.

During one expedition, Grix was studying the ruins of an old deserted castle and discovered a secret room littered with bones. In its center was a pedestal with Mortvilia - a book of the dead, made from human skin. Its pages were covered with warnings, but Grix decided not to stop. He found a spell that grants a person supernatural power.

Grix wanted to use the power for the benefit of humanity, so he began to read the spell. As soon as he read the first lines, the skin on his back burst and huge ugly wings grew from the wounds. The other members of the expedition, seeing this, decided that Grix had become a demon, so they attacked him. The frightened researcher dropped the book and fled, and his colleagues burned the cursed tome so that no one else would turn into a monster.

For many centuries, Grix wandered the Sphere, collecting artifacts and ancient scrolls to return to his human form. So far, he has not succeeded, and he still walks the world with cursed wings on his back.
