The player's tribe is represented by the colour blue, while other tribes are red, yellow, green, purple and cobalt. Provinces under control from a random tribe with no possible relations to others are paper-coloured, and provinces controlled by the Spanish (once the Spanish arrive to invade) are grey. Each tribe has a unique 'personality' dictated by its AI; the red tribe the Izhuacans for example are an 'aggressive and warlike theocracy' and will generally be the first tribe to make an aggressive move in the game. The green tribe, the Huaputecs, are more peaceful and will never attack the player unless the player has already initiated hostilities. Tribes also have varying military tactics and units, the Yellow Tribe has an army consisting of almost entirely sword units supported by spearmen, jaguars and nature priests, while the Cyan tribe, the Teotitlans, have enormous crossbow units known as Wonderbows and soul priests supporting their warriors.
