With this expansion, the game of Tzolk'in: The Mayan Calendar is also influenced by three prophecies that are revealed ahead of time and fulfilled when the time is right. These prophecies give players other opportunities to score points, but they can also lose points if they don't prepare themselves for the prophecy effects. As with the tribes, the expansion includes 13 prophecies. (Woohoo, 13 again!)

This expansion also has new buildings and components that allow up to five players to compete.
