The native population of Illarreen tends to be as temperate as the planetary climate. The last world war to break centuries of peace was instigated by an off-worlder – the force-wielder and self-proclaimed overlord of Illarreen, Ecris Tes`je. The rule of the sorcerer managed to divide the population and pitted the agrarian communities of the south and west against the industrialized north and east. A decade later, the unexplained death of Tes`je ended the fighting. Within a generation, the population returned to its passive equilibrium, and the monarchy was restored. A spiritual people -- the daily life of an Illarreenian is filled with devotions to their pantheon of nature gods to the point that every act which they perform is to be in the service of a god. The gods are believed to reside within the dark jungles of the Monah Plateau, which is surrounded by volcanic fields like a moat about its base.

Clusters of civilization are dispersed across the planet, but an oceanic people, most Illarreenians will make a pilgrimage to the northern seashore at least once every other year. The ocean of the northern hemisphere is known by the name of its goddess, Borliha, while in the south lies the Enorika. The warmer waters of the Borliha support an ecosystem as diverse as that which lies on the land. The Enorika, however, has a much higher salinity and as a result, only small, sprite-like creatures known as Piks live in its pale, blue-green waters.
