It was with this understanding that sand ships came into being.
These were elongated transport vehicles encased in a special alloy.
They resembled metal airships.
Compared to normal ships, sand ships were more like submarines, completely sealed to protect the humans inside.
Their shape was also very different from a normal "ship," because a sand ship's purpose wasn't to float on water, but to travel through waves of sand.
Of course, sand ships also had the same facilities as normal ships, since they were, after all, meant to carry people.
Sand ships required no power at all. Their only function was to protect people from harm within the sand waves.
All sorts of creatures lived within the sand waves, and these creatures would forage for food in them.
They weren't picky and would devour any object swept up by the sand waves.
Naturally, sand ships were also part of their diet.
