Bound elementals form the corner stone of the world’s technology. Bound fire elementals lift airships to the skies and heat water in homes, bound water elementals propel ships across the seas and provide limitless clean water.
The elementals are bound into elemental gems and then sold by the Mercantile Empire of the Djinn. The Empire is the only source for bound elementals and they guard their monopoly fiercely.
The process of binding the elementals is a secret known only to the Master Binders of the Mercantile Empire. The protection of these Masters exceeds that of even the Empress.
