In the tongue of the people of that time, Traveler, the year, the year in which the end of the Fifth Sun was announced, was called 1975. This means, Honored Visitor, that the Fifth Sun will end, on a day Nahui Ollin, before the year 2027.

In my dream, I heard them say that the stars had been seen, clearly, at the beginning of the last Bundle of Years. That, I heard them say, was the year 1923. But in 1975, they said, there was too much of something over the Anahuac, which they called "Mexico City," for them to see the stars as they crossed.

I do not know, Traveler, what this something was. The word makes no sense to me. But whatever it was, it announced the death of the Fifth Sun.

They called it "smog."
