Challenge: Gold Book of the Living
The priests took time to ensure that the book was the exact fit to the statues base. It was something that should never be found. The book was too powerful for any dynasty. They had taken the same care with the black book. But the gold book needed protection. For should the black book be discovered only the gold counterpart could undo any wrong that would be unleashed. And it most certainly would be unleashed. For even under the best intentions, man failed to see that things should not change to help the living and the dead must move on.
