Tiefling majordomo / caravan master
The tiefling known as Johnson started as the majordomo of Felix, the demonic fight promoter.
That is until he went against Felix’s will and helped the people gathered at SaharaBellum. He stole a scroll of weather control and brought rain to the area, providing everyone with a source of untainted drinking water.
Johnson was then cast out and left to fend for himself. Johnson had long been Felix’s caravan master before Felix aquired magic that made travel by caravan unnecessary. This was a great coincidence as the party had aquired mounts, but knew nothing about traveling the desert.
