Magnus’s RPG empire on the portal.

You found the grave, he is in the coffin, you opened the sarcophagus, but the body is still warm, you took out the heart, it is still beating, you ate the heart, suddenly everything went blurry in your eyes and you realized that all the Ashas and elemental dragons have turned away from you, and you will not receive blessings in their temples, but only harm.
