We are in one of the Gear Rooms for Kadmeion’s airship. Step over here. I want to show you something.
Some of the automata have removed the hull’s inner wall boards so you can see the floating rocks that miners have cut into bricks. The mortar holds the bricks in place. The wall boards keep the bricks from wandering about the room if they work themselves free.
Why do some rocks float? It has to do with the South Pole at the spindle.
Volcanic activity at the pole heats rocks until they melt. This intense heat causes the latent magic to transform the liquid rock until it is lighter than air. The strings of rock flow upward, collect into top-heavy spires, and cool. Earthquakes break the islands free of their fragile spires. The islands hover close to the ground where plants, birds, and animals jump onto their new home. They finally float to the edge of the South Pole landmass and go out to sea.
Mathematicians can calculate a floating island’s age by its size, distance from the South Pole, and its height above the sea. Old islands lose their buoyancy and sink closer to the sea. Some of the oldest islands rest it the sea for a time before the Rim storms tear them apart.
Let’s go see the Crew Quarters next.
