Our world exploded into many different pieces. The people who live on this world have since put it back together using large cables, basically making a world out of floating islands. The vehicle that we have designed is meant to be able to travel inbetween the islands on the cables that hold them together. This specific vehicle is actually meant to haul spices around to other islands because spices are the new currency but in general it's just meant to be able to travel inbetween the islands.
