With Tzolk'in: Tribes and Prophecies, players become the mighty leaders of their own tribes, caring for the welfare of their people. Each tribe has unique gifts. Players can lead the wealthy Ixtab, the numerous Yaluk, the industrious Ah Chuy Kak, or any of the 10 other tribes.

Wise leadership will be needed, for prophets have foreseen three calamities that will befall the Maya. Those who neglect the prophecies shall perish, but those who heed the warnings and plan ahead shall lead their tribes to greater glory.

This expansion also includes new buildings and components that can expand Tzolk'in to a 5-player game.
