August was the peak of the rainy season. The deities had opened the passage between the Heavenly River and the human world, and the heavy rain poured down from the sky.
From the Great Temple at Lake Texcoco to the House of Wind by Lake Patzcuaro, the vast lands were engulfed in continuous wind and rain. The soft mud was filled with rainwater, and the blue stone walls were slick with wetness, making all fighting difficult, hence it gradually ceased.
With the sky full of wind and rain, Xiulote, dressed in a plain robe, stood on the watchtower of the wooden fort, looking east towards the Lerma River, waiting for the returning fleet. As far as he could see, the curtain of rain was continuous, the nearby river water rose incessantly, and the river surface widened. The river then surged westward, tumultuous with waves.
