The game takes place in Mexico and Central America in the 1400s. You control a tribe and have 100 years to prepare for a Spanish invasion by expanding their territory across the Central American map, by conquest, or by allying and trading with other tribes. Build pyramids to harness the power of Magic from the five spheres of Magic: : Sun sphere priests are masters of attack spells, moon priests in defence, nature priests in healing, soul priests in attack and betrayal and star priests in poison.
