The game opening text for certain roles is changed from “It is written in the Book of [deity]:”

• Wizard: “It is inscribed in the Tomes of [deity]”
• Barbarian: “It is carved on the Stone Tablets of [deity]”
• Archeologist: “It is written in the ancient Scrolls of [deity]”
• Priest: “It is taught in the Temple of [deity]”
