Cobalt has lived his entire life inside Stable 18. With supplies running low Cobalt and several of his friends were selected to venture into the wasteland to establish some trade with settlements that lived on the surface. As he adjusts to life outside of the stable Cobalt crosses paths with a legendary raider boss called the Sledge. The Sledge takes a liking Cobalt and invites him to join his gang. Little does Cobalt know what kind of an adventure he was singing up for.
