Airship

Airships generally use a number of large, expensive crystals capable of high volumes of magical capacitance. These crystals tend to be between 3-4 feet tall and 2-3 feet wide and number from three to twelve depending on the size of the ship and capacitance of the individual crystals.

Recently, the Kore Department of Development announced it was working on developing a prototype airship powered by numenite crystals. While much rarer than other crystals, much fewer could potentially be used to power a single ship and without the need to periodically recharge.

Crystals can be used to power airship levitation devices, making them float and providing some drift in a given direction. This can be useful when needing to make slight adjustments when docking or undocking. In some cases, blimp-like balloons are used to provide a secondary and less magically (and monetarily) expensive form of supplemental levitation.

While crystals are useful in providing lift, they are considered only a secondary form of propulsion by themselves. Once they get out into the open air, airships require more intentional propulsion systems to combat air currents, and move at a speed that warrants their usage in the first place over more mundane means of travel that would otherwise move faster than the propulsion the crystals provide alone. Depending on the size and function, airship propulsion can take a variety of forms. The most common examples include propellers, wing-like oar systems, and sails.
