Celestine is the Realm of Air. Home of the Djinn and the dominion of the goddess Oriel, it is a masterpiece of architecture carved from porcelain and gold, decorated with nacre and gems that glisten in the sunlight. The city itself is built on the highest clouds, travelling with them over the lands below.
The halls of Celestine are carved so that the winds constantly blowing through them make music, as they follow the twists and coils of the corridors. Often this means that the sound of light flutes can always be heard in the palace, no matter where you are. Celestine is hard to access due to its height, and it is protected from the attacks of the Others by a giant shield of hardened air, powered by a large pearl in the heart of the city.
