Changes

The Tau are originally were a plains-dwelling race. In their prehistory, they lived in tribes on the desert plains, hunting and gathering their foodand resources. As their race aged, they expanded to occupy all environments. The Tau of the plains became strong and skillful hunters, larger and stronger than most other Tau. The Tau of the mountains developed the ability to soar high above the baking deserts on thermals. The Tau of the river valleys developed agriculture and metallurgy, forming the first true settlements. The development of settlements led to the need of trade, and wandering Tau began to negotiate and mediate between the disparate tribes. It wasn't long before the tau were the dominant species on thier planet.
