Unique to Melee Island, airstones are a glassy green in appearance and naturally channel forces from the Elemental Chaos. Once they are refined, the stones can be made to hover or fly and can support massive weights.
Before being processed by alchemists and mages, the stones are either dormant or given to sudden bursts of energy which cause them to jump or hover.
The Dwenressia Empire used air-stones to create their fleet of airships, and have made ownership of the stones illegal.
Melee Island’s airstone mines were shut down by the Dwenressia Empire after they had mined all they needed. The mines are now magically warded and regularly patrolled.
