Airship

Airships are an important mode of transport in Aurelia. Commercial airship travel is available to many people of Aurelia, but for most they only ever see them from below. Watching airships fly by, dock or lift off is a respected past time among many Aurelians.
An airship shares a number of features with naval ship. Airship crews are similarly organized in their hierarchies and the names of ranks. Many airships could probably swim on water, but very few captains will actually test this unless they have to. The biggest issue is that the airship hull is not coated with something to make it fully water tight, meaning that they will likely have some smaller leaks.
At the core of an airship is the Gravity Stone. These stones can influence the gravity around them. Making the ship simply float in the air. Strong winds can still enter this zone and push the airship along. A change in height can only be achieved with a complex set of enchantments that allow the navigator to influence the gravity stone. To maintain the ships height the stone nullifies the gravity entirely. To change altitude a weak gravity is created that pulls the ship down or up.
Airships use wind to navigate the sky, as a result navigators and captains need a deep understanding of the wind systems of Aurelia. There are ways to affect the winds in a way that allows navigation beyond these wind systems, but these usually require a lot of resources and are reserved for military airships or other important travels.
