"The Hopi people have warned us that the world is headed for extinction. Based in the Arizona Desert, the Native American tribe of the Hopi has been prophesying about the fate of society for centuries, in Season 1, Episode 4, "Hopi Blue Star.""
"The Blue Star Katsina prophecy is a Hopi revelation about the coming end of civilization on
Earth. The prophecy describes a heavenly being called the Blue Star whose arrival on Earth will
signal the beginning of the end times.
The Blue Star Katsina has a twin brother, the Red Star Katsina, whose arrival will come later,
bringing about the destruction of most life on Earth. According to the prophecy, the Hopi will
survive the apocalypse in an underground refuge and resurface when the time is right."
