The three ancient forbidden books Viska had "stolen" recorded prewar history that the Goddess Church had deliberately downplayed. Though these three books revealed only a faint glimmer of history, that glimmer was enough to show us a world utterly different from the one promoted by the Church—a world where all races did not live in harmony, but where both the land and the moon were filled with opposition, discrimination, conflict, and even slavery.
The true history was as follows:

Since the first intelligent creature to invent writing recorded what he saw on bark and stone slabs, the world had consisted of two parts. These two parts were a pair of twin-like planets. In the unimaginably distant ancient era, they had been called Redemund and Heisenwood. Those two names were recorded in ancient books, but no one now knew their exact meanings. After comparing the records, we could only determine that Redemund was today's "Dark Moon," while Heisenwood was the planet inhabited by Surface Dwellers.
