The Wheel, also known as The Circle, is a doughnut-shaped object. The first wheels were made of rock, later designs of the wheel are made out of rubber. The Wheel was made by a renowned caveman named Urgh-Urgh. He was minding his own business when the god of Un'tu appeared in front of him and gave him schematics to make the first wheel, though this story most likely is false due to Urgh-Urgh being very ignorant. He might have stole the design from an exile or a chieftain. Wheels are used for chariots, war chariots, and a mortal. Lastly, the wheel is need to make roads.
