Ganchalov reported the legend he had heard to Marvin, as narrated by Yuniya.
Marvin took the Aztec mythology seriously. For a long time, he had been collecting historical documents, whether intentionally or unintentionally, to learn about the history from two thousand years ago and crack the conspiracy of the Ancient Gods.
There were many documents recording history, but they were limited to the past two thousand years. Other records were either lost or damaged, leaving nothing behind.
It was the same with the Church of the Three Goddesses' library, where the room originally storing historical documents had been gnawed open by rats, and the papers were all rotten, making the text indecipherable.
The only clues left were the doctrines of the Church of the Three Goddesses and various myths and legends from different regions, since these orally transmitted stories couldn't be completely erased.
