Build a functioning society of Aztec Jaguars by sacrificing people to the Gods in order to gain Favor and keep your people alive by summoning Rain and Thunder from the skies. Expand your domain while always being set back by the very forces that will assist you. Protect your city from evil heretical Aligators, farm the land and provide an equivalent exchange of Death into Life before all falls apart once the Feathered Serpent arrives at the dawn of the 15th day.
