Yeah I was thinking that as well. Whom would be the leader though?
Thankyou Drakar for the suggestion. A desert-based combat bonus is what I had in mind.
There is no written record for Anasazi, but according to Chief Sun Cloud's (Hopi) oral histories, the first Anasazi Great Chief was Itzukuma.
A little historical background; Anasazi as a group were actually Hopi, Zuni, Pueblo, and Acoma, and started roughly 1500bc and then started to vanish approximately 1200ad.
Anasazi itself, is actually an insult towards the Hopi, meaning "ancient enemy". The Hopi preferred to be called the "Old Ones" (and I forget the native name, sorry), and were the ones who primarily were the engineers of the great cliff house system at Chaco Canyon.
Chaco Canyon rivaled Cahokia in power and trade, as well as engineering (the only American natives to build complex cities inside a 600' + cliff). Additionally, there is some theories that the Anasazi traded with the Aztecs. Since the Pueblo only keep their histories in oral tradition, and are notoriously secretive about it, it makes it extremely difficult to gather any type of info about key figures.
The Great Chief was in all aspects similar to a mayor, or Governor in todays political society. He had a council of Chiefs (one from each of the four major tribes), a Shaman, and a Sprit Walker (according to legend, aliens visited the Anasazi and taught them some things, would explain their engineering skills

) in order to get answers from the spirit world.
As for your leader head, you could probably use an old B&W image of one of the four tribes and insert the great chief's name....
I really gotta stop going into historical mode @ 4am in the morning, lol. Just trying to help guys.
