You were a traveling mechanic, working in wood and metal and glass out of necessity, the back of your van-turned-wagon an entire workshop in itself. There were always those who means of transit broke down along the endless roads, and when you found them you could often fix what had broken, and provide the work to stop the next few likely breakdowns from happening. Your trade was the closest thing the Vault had to a general faith, and vans like yours grew increasingly common over your life - the drive to help others as strong among the wanderers of the road as among any other people across the Infinity of Infinities.
